building types and designA building is closely bound up with people,for it provides with the necessary space to work and live in .As classified by their use ,buildings are mainly of two types :industrial buildings and civil buildings .industrial buildings are used by various factories or industrial production while civil buildings are those that are used by people fordwelling ,employment ,education and other social activities .Industrial buildings are factory buildings that are available for processing and manufacturing of various kinds ,in such fields as the mining industry ,the metallurgical industry ,machine building ,the chemical industry and the textile industry . factory buildings can be classified into two types single-story ones and multi-story ones .the construction of industrial buildings is the same as that of civil buildings .however ,industrial and civil buildings differ in the materials used and in the way they are used .Civil buildings are divided into two broad categories: residential buildings and public buildings .residential buildings should suit family life .each flat should consist of at least three necessary rooms : a living room ,a kitchen and a toilet .public buildings can be used in politics ,cultural activities ,administration work and other services ,such as schools, office buildings,parks ,hospitals ,shops ,stations ,theatres ,gymnasiums ,hotels ,exhibition halls ,bath pools ,and so on .all of them have different functions ,which in turn require different design types as well.Housing is the living quarters for human beings .the basic function of housing is to provide shelter from the elements ,but people today require much more that of their housing .a family moving into a new neighborhood will to know if the available housing meets its standards of safety ,health ,and comfort .a family will also ask how near the housing is to grain shops ,food markets ,schools ,stores ,the library ,a movie theater ,and the community center .In the mid-1960’s a most important value in housing was sufficient space both inside and out .a majority of families preferred single-family homes on about half an acre of land ,which would provide space for spare-time activities .in highly industrialized countries ,many families preferred to live as far out as possible from the center of a metropolitan area ,even if the wage earners had to travel some distance to theirwork .quite a large number of families preferred country housing to suburban housing because their chief aim was to get far away from noise ,crowding ,and confusion .the accessibility of public transportation had ceased to be a decisive factor in housing because most workers drove their cars to work .people we’re chiefly interested in the arrangement and size of rooms and the number of bedrooms .Before any of the building can begin ,plans have to be drawn to show what the building will be like ,the exact place in which it is to go and how everything is to be done.An important point in building design is the layout of rooms ,which should provide the greatest possible convenience in relation to the purposes for which they are intended .in a dwelling house ,the layout may be considered under three categories : “day”, “night” ,and “services” .attention must be paid to the provision of easy commun ication between these areas .the “day “rooms generally include adining-room ,sitting-room and kitchen ,but other rooms ,such as a study ,may be added ,and there may be a hall .the living-room ,which is generally the largest ,often serves as a dining-room ,too ,or the kitchen may have a dining alcove .the “night “rooms consist of the bedrooms .the “services “comprise thekitchen ,bathrooms ,larder ,and water-closets .the kitchen and larder connect the services with the day rooms .It is also essential to consider the question of outlook from the various rooms ,and those most in use should preferably face south as possible .it is ,however ,often very difficult to meet the optimum requirements ,both on account of the surroundings and the location of the roads .in resolving these complex problems ,it is also necessary to follow the local town-planning regulations which are concerned with public amenities ,density of population ,height of buildings ,proportion of green space to dwellings ,building lines ,the general appearance of new properties in relation to the neighbourhood ,and so on .There is little standardization in industrial buildings although such buildings still need to comply with local town-planning regulations .the modern trend is towardslight ,airy factory buildings .generally of reinforced concrete or metal construction ,a factory can be given a “shed ”type ridge roof ,incorporating windows facing north so as to give evenly distributed natural lighting without sun-glare .翻译:建筑类型和设计建筑物与人们有着紧密的联系,他为人们提供必要的空间,用以工作和生活。

外文资料:Prestressed Concrete BuildingsPrestressed concrete has been widely and successfully applied to building construction of all types.Both precast pretensioned members and cast-tensioned structures are extensively employed,sometimes in competition with one another, most effectively in combination wit each other.Prestressed concrete offers great advantages for incorporation in a totalaspects of these, that is, structure plus other building. It is perhaps the “integrative”functions,which have made possible the present growth in use of prestressed concrete buildings.These advantages include the following:Structural strength; Structure rigidity;Durability;Mold ability,into desired forms and shapes;Fire resistance;Architectural treatment of surfaces;Sound insulation;Heat insulation; Economy; Availability, through use of local materials and labor to a high degree.Most of the above are also properties of conventionally reinforced concrete. Presrressing,however,makes the structural system more effective by enabling elimination of the technical of difficulty,e.g.,cracks that spoil the architectural treatment.Prestressing greatly enhance the structure efficiency and economy permitting longer spans and thinner elements.Above all,it gives to the architect-engineer a freedom for variation and an ability to control behavior under service conditions.Although prestressed concrete construction involves essentially the same consideration and practices as for all structures, a number of special points require emphasis or elaboration.The construction engineer is involved in design only to a limited extent. First,he muse be able to furnish advice to the architect and engineer on what can he done. Because of his specialized knowledge of techniques relating to prestressed concrete construction, he supplies a very needed service to the architect-engineer.Second, the construction engineer may be made contractually responsible for the working drawings;that is,the layout of tendons,anchorage details,etc.It is particularly important that he gives careful attention to the mild steel and concrete details to ensure these are compatible with his presressing details.Third, the construction engineer is concerned with temporary stresses, stresses at release, stresses in picking, handling and erection, and temporary condition prior to final completion of the structure, such as the need of propping for a composite pour.Fourth,although the responsibility for design rests with the design engineer, nevertheless the construction engineer is also vitally concerned that the structure be successful form the point of view of structural integrity and service behavior. Therefore he will want to look at the bearing and connection details, camber, creep, shrinkage,thermal movements,durability provisions,etc.,and advise the design engineer of any deficiencies he encounters.Information on new techniques and especially application of prestressing to buildings are extensively available in the current technical literature of national and international societies.The International Federation of Prestressing(I.F.P)has attempted to facilitate the dissemination of this information by establishing a Literature Exchange Service,in which the prestressing journals of some thirty countries are regularly exchanged.In addition,an Abstract is published intermittently by I.F.P The Prestressed Concrete Institute(USA)regularly publishes a number of journals and pamphlets on techniques and applications, and proceduresare set up for their dissemination to architects and engineers as well as directly to the construction engineer. It is important that he keep abreast of these national and worldwide developments, so as to be able to recommend the latest and best that is available in the art,and to encourage the engineer to make the fullest and most effective use of prestressed concrete in their buildings.With regard to working drawings, the construction engineer must endeavor to translate the design requirements into the most practicable and economical details of accomplishment,in such a way that the completed element or structure fully complies with the design requirement;for example, the design may indicate only the center of gravity of prestressing and the effective prestress force. The working drawing will have to translate this into tendons having finite physical properties and dimensions.If the center of gravity of pre-stressing is a parabolic path then,for pre-tensioning,and approximation by chords is required,with hold-down points suitably located.The computation of pre-stress losses,form transfer stress to effective stress, must reflect the actual manufacturing and construction process used,as well as thorough knowledge of the properties of the particular aggregates and concrete mix to be employed.With post-tensioning, anchorages and their bearing plates must be laid out in their physical dimension. It is useful in the preparation of complex anchorage detail layouts to use full-scale drawings, so as to better appreciate the congestion of mild steel and anchorages at the end of the member. Tendons and reinforcing bars should be shown in full size rather than as dotted lines. This will permit consideration to be given as to how the concrete can be placed and consolidated.The end zone of both pre-tensioned and post-tensioned concrete memberssubject to high transverse or bursting stresses. These stresses are also influenced by minor concrete details,such as chamfers.Provision of a grid of small bars (sometimes heavy wire mesh is used), as close to the end of a girder as possible, will help to confine and distribute the concentrated forces. Closely spaced stirrups and/or tightly spaced spiral are usually needed at the end of heavily stressed members.Recent tests have confirmed that closeness of spacing is much more effective than increase in the size of bars. Numerous small bars, closely spaced, are thus the best solution.Additional mild-steel stirrups may also be required at hold-down points to resist the shear. This is also true wherever post-tensioned tendons make sharp bends. Practical consideration of concretion dictates the spacing of tendons and ducts. The general rules are that the clear spacing small be one-and-one-half times the maximum size of coarse aggregate. In the overall section, provision must be made for the vibrator stinger.Thus pre-stressing tendons must either be spaced apart in the horizontal plane, or, in special cases, bundled.In the vertical plane close contact between tendons is quite common.With post-tensioned ducts,however,in intimate vertical contact,careful consideration has to be given to prevent one tendon form squeezing into the adjacent duct during stressing.This depends on the size of duct and the material used for the duct.A full-scale layout of this critical cross section should be ually,the best solution is to increase the thickness ( and transverse strength ) of the duct, so that it will span between the supporting shoulders of concrete.As a last rest\ort it may be necessary to stress and grout one duct before stressing the adjacent one.This is time-consuming and runs the risks of grout blockage due to leaks from one duct to the other. Therefore the author recommendsthe use of heavier duct material,or else the respacing of the ducts.The latter,of course, may increase the prestressing force required.中文翻译:预应力混凝土建筑预应力混凝土已经广泛并成功地用于各种类型的建筑。

While the style was conceived early in the 20th century and heavily promoted by a few architects, architectural educators and exhibits, very few Modern buildings were built in the first half of the century. For three decades after the Second World War, however, it became the dominant architectural style for institutional and corporate building.1. OriginsSome historians see the evolution of Modern architecture as a social matter, closely tied to the project of Modernity and hence to the Enlightenment, a result of social and political revolutions.Others see Modern architecture as primarily driven by technological and engineering developments, and it is true that the availability of new building materials such as iron, steel, concrete and glass drove the invention of new building techniques as part of the Industrial Revolution. In 1796, Shrewsbury mill owner Charles Bage first used his ‘fireproof’ design, which relied on cast iron and brick with flag stone floors. Such construction greatly strengthened the structure of mills, which enabled them to accommodate much bigger machines. Due to poor knowledge of iron's properties as a construction material, a number of early mills collapsed. It was not until the early 1830s that Eaton Hodgkinson introduced the section beam, leading to widespread use of iron construction, this kind of austere industrial architecture utterly transformed the landscape of northern Britain, leading to the description, "Dark satanic mills" of places like Manchester and parts of West Yorkshire. The Crystal Palace by Joseph Paxton at the Great Exhibition of 1851 was an early example of iron and glass construction; possibly the best example is the development of the tall steel skyscraper in Chicago around 1890 by William Le Baron Jenney and Louis Sullivan. Early structures to employ concrete as the chief means of architectural expression (rather than for purely utilitarian structure) include Frank Lloyd Wright's Unity Temple, built in 1906 near Chicago, and Rudolf Steiner's Second Goetheanum, built from1926 near Basel, Switzerland.Other historians regard Modernism as a matter of taste, a reaction against eclecticism and the lavish stylistic excesses of Victorian Era and Edwardian Art Nouveau.Whatever the cause, around 1900 a number of architects around the world began developing new architectural solutions to integrate traditional precedents (Gothic, for instance) with new technological possibilities. The work of Louis Sullivan and Frank Lloyd Wright in Chicago, Victor Horta in Brussels, Antoni Gaudi in Barcelona, Otto Wagner in Vienna and Charles Rennie Mackintosh in Glasgow, among many others, can be seen as a common struggle between old and new.2. Modernism as Dominant StyleBy the 1920s the most important figures in Modern architecture had established their reputations. The big three are commonly recognized as Le Corbusier in France, and Ludwig Mies van der Rohe and Walter Gropius in Germany. Mies van der Rohe and Gropius were both directors of the Bauhaus, one of a number of European schools and associations concerned with reconciling craft tradition and industrial technology.Frank Lloyd Wright's career parallels and influences the work of the European modernists, particularly via the Wasmuth Portfolio, but he refused to be categorized with them. Wright was a major influence on both Gropius and van der Rohe, however, as well as on the whole of organic architecture.In 1932 came the important MOMA exhibition, the International Exhibition of Modern Architecture, curated by Philip Johnson. Johnson and collaborator Henry-Russell Hitchcock drew together many distinct threads and trends, identified them as stylistically similar and having a common purpose, and consolidated them into the International Style.This was an important turning point. With World War II the important figures of the Bauhaus fled to the United States, to Chicago, to the Harvard Graduate School of Design, and to Black Mountain College. While Modern architectural design never became a dominant style in single-dwelling residential buildings, in institutional and commercial architecture Modernism became the pre-eminent, and in the schools (for leaders of the profession) the only acceptable, design solution from about 1932 to about 1984.Architects who worked in the international style wanted to break with architectural tradition and design simple, unornamented buildings. The most commonly used materials are glass for the facade, steel for exterior support, and concrete for the floors and interior supports; floor plans were functional and logical. The style became most evident in the design of skyscrapers. Perhaps its most famous manifestations include the United Nations headquarters (Le Corbusier, Oscar Niemeyer, Sir Howard Robertson), the Seagram Building (Ludwig Mies van der Rohe), and Lever House (Skidmore, Owings, and Merrill), all in New York. A prominent residential example is the Lovell House (Richard Neutra) in Los Angeles.Detractors of the international style claim that its stark, uncompromisingly rectangular geometry is dehumanising. Le Corbusier once described buildings as "machines for living", but people are not machines and it was suggested that they do not want to live in machines. Even Philip Johnson admitted he was "bored with the box." Since the early 1980s many architects have deliberately sought to move away from rectilinear designs, towards more eclectic styles. During the middle of the century, some architects began experimenting in organic forms that they felt were more human and accessible. Mid-century modernism, or organic modernism, was very popular, due to its democratic and playful nature. Alvar Aalto and Eero Saarinen were two of the most prolific architects and designers in this movement, which has influenced contemporary modernism.Although there is debate as to when and why the decline of the modern movement occurred, criticism of Modern architecture began in the 1960s on the grounds that it was universal, sterile, elitist and lacked meaning. Its approach had become ossified in a "style" that threatened to degenerate into a set of mannerisms. Siegfried Giedion in the 1961 introduction to his evolving text, Space, Time and Architecture (first written in 1941), could begin "At the moment a certain confusion exists in contemporary architecture, as in painting; a kind of pause, even a kind of exhaustion." At the Metropolitan Museum of Art, a 1961 symposium discussed the question "Modern Architecture: Death or Metamorphosis?" In New York, the coup d'état appeared to materialize in controversy around the Pan Am Building that loomed over Grand Central Station, taking advantage of the modernist real estate concept of "air rights",[1] In criticism by Ada Louise Huxtable and Douglas Haskell it was seen to "sever" the Park Avenue streetscape and "tarnish" the reputations of its consortium of architects: Walter Gropius, Pietro Belluschi and thebuilders Emery Roth & Sons. The rise of postmodernism was attributed to disenchantment with Modern architecture. By the 1980s, postmodern architecture appeared triumphant over modernism, including the temple of the Light of the World, a futuristic design for its time Guadalajara Jalisco La Luz del Mundo Sede International; however, postmodern aesthetics lacked traction and by the mid-1990s, a neo-modern (or hypermodern) architecture had once again established international pre-eminence. As part of this revival, much of the criticism of the modernists has been revisited, refuted, and re-evaluated; and a modernistic idiom once again dominates in institutional and commercial contemporary practice, but must now compete with the revival of traditional architectural design in commercial and institutional architecture; residential design continues to be dominated by a traditional aesthetic.中⽂译⽂:现代建筑现代建筑,不被混淆与'当代建筑' , 是⼀个词给了⼀些建筑风格有类似的特点, 主要的简化形式,消除装饰等. 虽然风格的设想早在20世纪,并⼤量造就了⼀些建筑师、建筑教育家和展品,很少有现代的建筑物,建于20世纪上半叶. 第⼆次⼤战后的三⼗年, 但最终却成为主导建筑风格的机构和公司建设.1起源⼀些历史学家认为进化的现代建筑作为⼀个社会问题, 息息相关的⼯程中的现代性,从⽽影响了启蒙运动,导致社会和政治⾰命.另⼀些⼈认为现代建筑主要是靠技术和⼯程学的发展, 那就是获得新的建筑材料,如钢铁, 混凝⼟和玻璃驱车发明新的建筑技术,它作为⼯业⾰命的⼀部分. 1796年, shrewsbury查尔斯bage⾸先⽤他的'⽕'的设计, 后者则依靠铸铁及砖与⽯材地板. 这些建设⼤⼤加强了结构,使它们能够容纳更⼤的机器. 由于作为建筑材料特性知识缺乏,⼀些早期建筑失败. 直到1830年初,伊顿Hodgkinson预计推出了型钢梁, 导致⼴泛使⽤钢架建设,⼯业结构完全改变了这种窘迫的⾯貌,英国北部领导的描述, "⿊暗魔⿁作坊"的地⽅如曼彻斯特和西约克郡. ⽔晶宫由约瑟夫paxton的重⼤展览, 1851年,是⼀个早期的例⼦,钢铁及玻璃施⼯; 可能是⼀个最好的例⼦,就是1890年由William乐男爵延长和路易沙利⽂在芝加哥附近发展的⾼层钢结构摩天楼. 早期结构采⽤混凝⼟作为⾏政⼿段的建筑表达(⽽⾮纯粹功利结构) ,包括建于1906年在芝加哥附近,劳埃德赖特的统⼀宫, 建于1926年瑞⼠巴塞尔附近的鲁道夫斯坦纳的第⼆哥特堂,.但⽆论原因为何, 约有1900多位建筑师,在世界各地开始制定新的建筑⽅法,将传统的先例(⽐如哥特式)与新的技术相结合的可能性.路易沙利⽂和赖特在芝加哥⼯作,维克多奥尔塔在布鲁塞尔,安东尼⾼迪在巴塞罗那, 奥托⽡格纳和查尔斯景mackintosh格拉斯哥在维也纳,其中之⼀可以看作是⼀个新与旧的共同⽃争.2现代主义风格由1920年代的最重要⼈物,在现代建筑⾥确⽴了⾃⼰的名声. 三个是公认的柯布西耶在法国, 密斯范德尔德罗和⽡尔特格罗⽪乌斯在德国. 密斯范德尔德罗和格罗⽪乌斯为董事的包豪斯, 其中欧洲有不少学校和有关团体学习调和⼯艺和传统⼯业技术.赖特的建筑⽣涯中,也影响了欧洲建筑的现代艺术,特别是通过⽡斯穆特组合但他拒绝被归类与他们. 赖特与格罗⽪乌斯和Van der德罗对整个有机体系有重⼤的影响.在1932年来到的重要moma展览,是现代建筑艺术的国际展览,艺术家菲利普约翰逊. 约翰逊和合作者亨利-罗素阁纠集许多鲜明的线索和趋势, 内容相似,有⼀个共同的⽬的,巩固了他们融⼊国际化风格这是⼀个重要的转折点. 在⼆战的时间包豪斯的代表⼈物逃到美国,芝加哥,到哈佛⼤学设计⿊⼭书院. 当现代建筑设计从未成为主导风格单⼀的住宅楼,在成为现代卓越的体制和商业建筑, 是学校(专业领导)的唯⼀可接受的, 设计解决⽅案,从约1932年⾄约1984年.那些从事国际风格的建筑师想要打破传统建筑和简单的没有装饰的建筑物。

It is found that fire and the associ- ated effects on buildings is significantly different to other forms of loading such as gravity live loads, wind and earthquakes and their respective effects on the building structure. Fire events are derived from the human activities within buildings or from the malfunction of mechanical and electrical equipment provided within buildings to achieve a serviceable environment. It is therefore possible to directly influence the rate of fire starts within buildings by changing human behaviour, improved maintenance and improved design of mechanical and electricalsystems. Furthermore, should a fire develops, it is possible to directly influence the resulting fire severity by the incorporation of fire safety systems such as sprinklers and to provide measures within the building to enable safer egress from the building. The ability to influence the rate of fire starts and the resulting fire severity is unique to the consideration of fire within buildings since other loads such as wind and earthquakes are directly a function of nature. The possible approaches for designing a building for fire safety are presented using an example of a multi-storey building constructed over a railway line. The design of both the transfer structure supporting the building over the railway and the levels above the transfer structure are consideredin the context of current regulatory requirements. The principles and assumptions associ- ated with various approaches are discussed.1 INTRODUCTIONOther papers presented in this series consider the design of buildings for gravity loads, wind and earthquakes.The design of buildings against such load effects is to a large extent covered by engineering based standards referenced by the building regulations. This is not the case, to nearly the same extent, in the case of fire. Rather, it is building regulations such as the Building Code of Australia (BCA) that directly specify most of the requirements for fire safety of buildings with reference being made to Standards such as AS3600 or AS4100 for methods for determining the fire resistance of structural elements.The purpose of this paper is to consider the design of buildings for fire safety from an engineering perspective (as is currently done for other loads such as wind or earthquakes), whilst at the same time,putting such approaches in the context of the current regulatory requirements.At the outset,it needs to be noted that designing a building for fire safety is far more than simply considering the building structure and whether it has sufficient structural adequacy.This is because fires can have a direct influence on occupants via smoke and heat and can grow in size and severity unlike other effects imposed on the building. Notwithstanding these comments, the focus of this paper will be largely on design issues associated with the building structure.Two situations associated with a building are used for the purpose of discussion. The multi-storey office building shown in Figure 1 is supported by a transfer structure that spans over a set of railway tracks. It is assumed that a wide range of rail traffic utilises these tracks including freight and diesel locomotives. The first situation to be considered from a fire safety perspective is the transfer structure.This is termed Situation 1 and the key questions are: what level of fire resistance is required for this transfer structure and how can this be determined? This situation has been chosen since it clearly falls outside the normal regulatory scope of most build-ing regulations. An engineering solution, rather than a prescriptive one is required. The second fire situation (termed Situation 2) corresponds to a fire within the office levels of the building and is covered by building regulations. This situation is chosen because it will enable a discussion of engineering approaches and how these interface with the building regulations regulations––since both engineering and prescriptive solutions are possible.2 UNIQUENESS OF FIRE2.1 Introduction Wind and earthquakes can be considered to b Wind and earthquakes can be considered to be “natural” phenomena o e “natural” phenomena o e “natural” phenomena over which designers ver which designers have no control except perhaps to choose the location of buildings more carefully on the basis of historical records and to design building to resist sufficiently high loads or accelerations for the particular location. Dead and live loads in buildings are the result of gravity. All of these loads are variable and it is possible (although generally unlikely) that the loads may exceed the resistance of the critical structural members resulting in structural failure.The nature and influence of fires in buildings are quite different to those associated with other“loads” to which a building may be subjected to. The essential differences are described in the following sections.2.2 Origin of FireIn most situations (ignoring bush fires), fire originates from human activities within the building or the malfunction of equipment placed within the building to provide a serviceable environment. It follows therefore that it is possible to influence the rate of fire starts by influencing human behaviour, limiting and monitoring human behaviour and improving the design of equipment and its maintenance. This is not the case for the usual loads applied to a building.2.3 Ability to InfluenceSince wind and earthquake are directly functions of nature, it is not possible to influence such events to any extent. One has to anticipate them and design accordingly. It may be possibleto influence the level of live load in a building by conducting audits and placing restrictions on contents. However, in the case of a fire start, there are many factors that can be brought to bear to influence the ultimate size of the fire and its effect within the building. It is known that occupants within a building will often detect a fire and deal with it before it reaches a sig- nificant size. It is estimated that less than one fire in five (Favre, 1996) results in a call to the fire brigade and for fires reported to the fire brigade, the majority will be limited to the room of fire origin. Inoc- cupied spaces, olfactory cues (smell) provide powerful evidence of the presence of even a small fire. The addition of a functional smoke detection system will further improve the likelihood of detection and of action being taken by the occupants.Fire fighting equipment, such as extinguishers and hose reels, is generally provided within buildings for the use of occupants and many organisations provide training for staff in respect ofthe use of such equipment.The growth of a fire can also be limited by automatic extinguishing systems such as sprinklers, which can be designed to have high levels of effectiveness.Fires can also be limited by the fire brigade depending on the size and location of the fire at the time of arrival.2.4 Effects of FireThe structural elements in the vicinity of the fire will experience the effects of heat. The temperatures within the structural elements will increase with time of exposure to the fire, the rate of temperature rise being dictated by the thermal resistance of the structural element and the severity of the fire. The increase in temperatures within a member will result in both thermal expansion and,eventually,a reduction in the structural resistance of the member. Differential thermal expansion will lead to bowing of a member. Significant axial expansion willbe accommodated in steel members by either overall or local buckling or yielding of local- ised regions. These effects will be detrimental for columns but for beams forming part of a floorsystem may assist in the development of other load resisting mechanisms (see Section 4.3.5).With the exception of the development of forces due to restraint of thermal expansion, fire does not impose loads on the structure but rather reduces stiffness and strength. Such effects are not instantaneous but are a function of time and this is different to the effects of loads such as earthquake and wind that are more or less instantaneous.Heating effects associated with a fire will not be significant or the rate of loss of capacity will be slowed if:(a) the fire is extinguished (e.g. an effective sprinkler system)(b) the fire is of insufficient severity –– insufficient fuel, and/or(b) the fire is of insufficient severity(c)the structural elements have sufficient thermal mass and/or insulation to slow the rise in internal temperatureFire protection measures such as providing sufficient axis distance and dimensions for concrete elements, and sufficient insulation thickness for steel elements are examples of (c). These are illustrated in Figure 2.The two situations described in the introduction are now considered.3 FIRE WITHIN BUILDINGS3.1 Fire Safety ConsiderationsThe implications of fire within the occupied parts of the office building (Figure 1) (Situation 2) are now considered. Fire statistics for office buildings show that about one fatality is expected in an office building for every 1000 fires reported to the fire brigade. This is an orderof magnitude less than the fatality rate associated with apartment buildings. More than two thirdsof fires occur during occupied hours and this is due to the greater human activity and the greater use of services within the building. It is twice as likely that a fire that commences out of normal working hours will extend beyond the enclosure of fire origin.A relatively small fire can generate large quantities of smoke within the floor of fire origin.If the floor is of open-plan construction with few partitions, the presence of a fire during normal occupied hours is almost certain to be detected through the observation of smoke on the floor. The presence of full height partitions across the floor will slow the spread of smoke and possibly also the speed at which the occupants detect the fire. Any measures aimed at improving housekeeping, fire awareness and fire response will be beneficial in reducing the likelihood of major fires during occupied hours.For multi-storey buildings, smoke detection systems and alarms are often provided to give “automatic” detection and warning to the occupants. An alarm signal is also transm itted to the fire brigade.Should the fire not be able to be controlled by the occupants on the fire floor, they will need to leave the floor of fire origin via the stairs. Stair enclosures may be designed to be fire-resistant but this may not be sufficient to keep the smoke out of the stairs. Many buildings incorporate stair pressurisation systems whereby positive airflow is introduced into the stairs upon detection of smoke within the building. However, this increases the forces required to open the stair doors and makes it increasingly difficult to access the stairs. It is quite likely that excessive door opening forces will exist(Fazio et al,2006)From a fire perspective, it is common to consider that a building consists of enclosures formed by the presence of walls and floors.An enclosure that has sufficiently fire-resistant boundaries (i.e. walls and floors) is considered to constitute a fire compartment and to be capableof limiting the spread of fire to an adjacent compartment. However, the ability of such boundariesto restrict the spread of fire can be severely limited by the need to provide natural lighting (windows)and access openings between the adjacent compartments (doors and stairs). Fire spread via the external openings (windows) is a distinct possibility given a fully developed fire. Limit- ing the window sizes and geometry can reduce but not eliminate the possibility of vertical fire spread.By far the most effective measure in limiting fire spread, other than the presence of occupants, is an effective sprinkler system that delivers water to a growing fire rapidly reducing the heat being generated and virtually extinguishing it.3.2 Estimating Fire SeverityIn the absence of measures to extinguish developing fires, or should such systems fail; severe fires can develop within buildings.In fire engineering literature, the term “fire load” refers to the quantity of combustibles within an enclosure and not the loads (forces) applied to the structure during a fire. Similarly, fire load density refers to the quantity of fuel per unit area. It is normally expressed in terms of MJ/m2or kg/m 2of wood equivalent. Surveys of combustibles for various occupancies (i.e offices, retail,hospitals, warehouses, etc)have been undertaken and a good summary of the available data is given in FCRC (1999). As would be expected, the fire load density is highly variable. Publications such as the International Fire Engineering Guidelines (2005) give fire load data in terms of the mean and 80th percentile.The latter level of fire load density is sometimes taken asthe characteristic fire load density and is sometimes taken as being distributed according to a Gumbel distribution (Schleich et al, 1999).The rate at which heat is released within an enclosure is termed the heat release rate (HRR) and normally expressed in megawatts (MW). The application of sufficient heat to a combustible material results in the generation of gases some of which are combustible. This process is called pyrolisation.Upon coming into contact with sufficient oxygen these gases ignite generating heat. The rate of burning(and therefore of heat generation) is therefore dependent on the flow of air to the gases generated by the pyrolising fuel.This flow is influenced by the shape of the enclosure (aspect ratio), and the position and size of any potential openings. It is found from experiments with single openings in approximately cubic enclosures that the rate of burning is directly proportional to A h where A is the area of the opening and h is the opening height. It is known that for deep enclosures with single openings that burning will occur initially closest to the opening moving back into the enclosure once the fuel closest to the opening is consumed (Thomas et al, 2005). Significant temperature variations throughout such enclosures can be expected.The use of the word ‘opening’ in relation to real building enclosures refers to any openings present around the walls including doors that are left open and any windows containing non fire-resistant glass.It is presumed that such glass breaks in the event of development of a significant fire. If the windows could be prevented from breaking and other sources of air to the enclosure limited, then the fire would be prevented from becoming a severe fire.V arious methods have been developed for determining the potential severity of a fire within an enclosure.These are described in SFPE (2004). The predictions of these methods are variable and are mostly based on estimating a representative heat release rate (HRR) and the proportion of total fuel ς likely to be consumed during the primary burning stage (Figure 4). Further studies of enclosure fires are required to assist with the development of improved models,as the behaviour is very complex.3.3 Role of the Building StructureIf the design objectives are to provide an adequate level of safety for the occupants and protection of adjacent properties from damage, then the structural adequacy of the building in fire need only be sufficient to allow the occupants to exit the building and for the building to ultimately deform in a way that does not lead to damage or fire spread to a building located on an adjacent site.These objectives are those associated with most building regulations including the Building Code of Australia (BCA). There could be other objectives including protection of the building against significant damage. In considering these various objectives, the following should be taken into account when considering the fire resistance of the building structure.3.3.1 Non-Structural ConsequencesSince fire can produce smoke and flame, it is important to ask whether these outcomes will threaten life safety within other parts of the building before the building is compromised by a lossof structural adequacy? Is search and rescue by the fire brigade not feasible given the likely extent of smoke? Will the loss of use of the building due to a severe fire result in major property and income loss? If the answer to these questions is in the affirmative, then it may be necessary to minimise the occurrence of a significant fire rather than simply assuming that the building structure needs to be designed for high levels of fire resistance. A low-rise shopping centre with levels interconnected by large voids is an example of such a situation.3.3.2 Other Fire Safety SystemsThe presence of other systems (e.g. sprinklers) within the building to minimise the occurrence of a serious fire can greatly reduce the need for the structural elements to have high levels of fire resistance. In this regard, the uncertainties of all fire-safety systems need to be considered. Irrespective of whether the fire safety system is the sprinkler system, stair pressurisation, compartmentation or the system giving the structure a fire-resistance level (e.g. concrete cover), there is an uncertainty of performance. Uncertainty data is available for sprinkler systems(because it is relatively easy to collect) but is not readily available for the other fire safety systems. This sometimes results in the designers and building regulators considering that only sprinkler systems are subject to uncertainty. In reality, it would appear that sprinklers systems have a high level of performance and can be designed to have very high levels of reliability.3.3.3 Height of BuildingIt takes longer for a tall building to be evacuated than a short building and therefore the structure of a tall building may need to have a higher level of fire resistance. The implications of collapse of tall buildings on adjacent properties are also greater than for buildings of only several storeys.3.3.4 Limited Extent of BurningIf the likely extent of burning is small in comparison with the plan area of the building, then the fire cannot have a significant impact on the overall stability of the building structure. Examples of situations where this is the case are open-deck carparks and very large area building such as shopping complexes where the fire-effected part is likely to be small in relation to area of the building floor plan.3.3.5 Behaviour of Floor ElementsThe effect of real fires on composite and concrete floors continues to be a subject of much research.Experimental testing at Cardington demonstrated that when parts of a composite floor are subject to heating, large displacement behaviour can develop that greatly assists the load carrying capacity of the floor beyond that which would predicted by considering only the behaviour of the beams and slabs in isolation.These situations have been analysed by both yield line methods that take into account the effects of membrane forces (Bailey, 2004) and finite element techniques. In essence, the methods illustrate that it is not necessary to insulate all structural steel elements in a composite floor to achieve high levels of fire resistance.This work also demonstrated that exposure of a composite floor having unprotected steel beams, to a localised fire, will not result in failure of the floor.A similar real fire test on a multistory reinforced concrete building demonstrated that the real structural behaviour in fire was significantly different to that expected using small displacement theory as for normal tempera- ture design (Bailey, 2002) with the performance being superior than that predicted by considering isolated member behaviour.3.4 Prescriptive Approach to DesignThe building regulations of most countries provide prescriptive requirements for the design of buildings for fire.These requirements are generally not subject to interpretation and compliance with them makes for simpler design approvalapproval––although not necessarily the most cost-effective designs.These provisions are often termed deemed-to-satisfy (DTS) provisions. Allcovered––the provision of emergency exits, aspects of designing buildings for fire safety are coveredspacings between buildings, occupant fire fighting measures, detection and alarms, measures for automatic fire suppression, air and smoke handling requirements and last, but not least, requirements for compartmentation and fire resistance levels for structural members. However, there is little evidence that the requirements have been developed from a systematic evaluation of fire safety. Rather it would appear that many of the requirements have been added one to anotherto deal with another fire incident or to incorporate a new form of technology. There does not appear to have been any real attempt to determine which provision have the most significant influence on fire safety and whether some of the former provisions could be modified.The FRL requirements specified in the DTS provisions are traditionally considered to result in member resistances that will only rarely experience failure in the event of a fire.This is why it is acceptable to use the above arbitrary point in time load combination for assessing members in fire. There have been attempts to evaluate the various deemed-to-satisfy provisions (particularly the fire- resistance requirements)from a fire-engineering perspective taking into account the possible variations in enclosure geometry, opening sizes and fire load (see FCRC, 1999).One of the outcomes of this evaluation was the recognition that deemed-to- satisfy provisions necessarily cover the broad range of buildings and thus must, on average, be quite onerous because of the magnitude of the above variations.It should be noted that the DTS provisions assume that compartmentation works and that fire is limited to a single compartment. This means that fire is normally only considered to exist at one level. Thus floors are assumed to be heated from below and columns only over one storey height.3.5 Performance-Based DesignAn approach that offers substantial benefits for individual buildings is the move towards performance-based regulations. This is permitted by regulations such as the BCA which state thata designer must demonstrate that the particular building will achieve the relevant performance requirements. The prescriptive provisions (i.e. the DTS provisions) are presumed to achieve these requirements. It is necessary to show that any building that does not conform to the DTS provisions will achieve the performance requirements.But what are the performance requirements? Most often the specified performance is simplya set of performance statements (such as with the Building Code of Australia)with no quantitative level given. Therefore, although these statements remind the designer of the key elements of design, they do not, in themselves, provide any measure against which to determine whether the design is adequately safe.Possible acceptance criteria are now considered.3.5.1 Acceptance CriteriaSome guidance as to the basis for acceptable designs is given in regulations such as the BCA. These and other possible bases are now considered in principle.(i)compare the levels of safety (with respect to achieving each of the design objectives) of the proposed alternative solution with those asso- ciated with a corresponding DTS solution for the building.This comparison may be done on either a qualitative or qualitative risk basis or perhaps a combination. In this case, the basis for comparison is an acceptable DTS solution. Such an approach requires a “holistic” approach to safety whereby all aspects relevant to safety, including the structure, are considered. This is, by far, the most common basis for acceptance.(ii)undertake a probabilistic risk assessment and show that the risk associated with the proposed design is less than that associated with common societal activities such as using pub lic transport. Undertaking a full probabilistic risk assessment can be very difficult for all but the simplest situations.Assuming that such an assessment is undertaken it will be necessary for the stakeholders to accept the nominated level of acceptable risk. Again, this requires a “holistic” approach to fire safety.(iii) a design is presented where it is demonstrated that all reasonable measures have been adopted to manage the risks and that any possible measures that have not been adopted will have negligible effect on the risk of not achieving the design objectives.(iv) as far as the building structure is concerned,benchmark the acceptable probability of failure in fire against that for normal temperature design. This is similar to the approach used when considering Building Situation 1 but only considers the building structure and not the effects of flame or smoke spread. It is not a holistic approach to fire safety.Finally, the questions of arson and terrorism must be considered. Deliberate acts of fire initiation range from relatively minor incidents to acts of mass destruction.Acts of arson are well within the accepted range of fire events experienced by build- ings(e.g. 8% of fire starts in offices are deemed "suspicious"). The simplest act is to use a small heat source to start a fire. The resulting fire will develop slowly in one location within the building and will most probably be controlled by the various fire- safety systems within the building. The outcome is likely to be the same even if an accelerant is used to assist fire spread.An important illustration of this occurred during the race riots in Los Angeles in 1992 (Hart 1992) when fires were started in many buildings often at multiple locations. In the case of buildings with sprinkler systems,the damage was limited and the fires significantly controlled.Although the intent was to destroy the buildings,the fire-safety systems were able to limit the resulting fires. Security measures are provided with systems such as sprinkler systems and include:- locking of valves- anti-tamper monitoring- location of valves in secure locationsFurthermore, access to significant buildings is often restricted by security measures.The very fact that the above steps have been taken demonstrates that acts of destruction within buildings are considered although most acts of arson do not involve any attempt to disable the fire-safety systems.At the one end of the spectrum is "simple" arson and at the other end, extremely rare acts where attempts are made to destroy the fire-safety systems along with substantial parts of thebuilding.This can be only achieved through massive impact or the use of explosives. The latter may be achieved through explosives being introduced into the building or from outside by missile attack.The former could result from missile attack or from the collision of a large aircraft. The greater the destructiveness of the act,the greater the means and knowledge required. Conversely, the more extreme the act, the less confidence there can be in designing against such an act. This is because the more extreme the event, the harder it is to predict precisely and the less understood will be its effects. The important point to recognise is that if sufficient means can be assembled, then it will always be possible to overcome a particular building design.Thus these acts are completely different to the other loadings to which a building is subjected such as wind,earthquake and gravity loading. This is because such acts of destruction are the work of intelligent beings and take into account the characteristics of the target.Should high-rise buildings be designed for given terrorist activities,then terrorists will simply use greater means to achieve the end result.For example, if buildings were designed to resist the impact effects from a certain size aircraft, then the use of a larger aircraft or more than one aircraft could still achieve destruction of the building. An appropriate strategy is therefore to minimise the likelihood of means of mass destruction getting into the hands of persons intent on such acts. This is not an engineering solution associated with the building structure.It should not be assumed that structural solutions are always the most appropriate, or indeed, possible.In the same way, aircrafts are not designed to survive a major fire or a crash landing but steps are taken to minimise the likelihood of either occurrence.The mobilization of large quantities of fire load (the normal combustibles on the floors) simultaneously on numerous levels throughout a building is well outside fire situations envisaged by current fire test standards and prescriptive regulations. Risk management measures to avoid such a possibility must be considered.4 CONCLUSIONSificantly from other “loads” such as wind, live load and earthquakes in significantlyFire differs signrespect of its origin and its effects.Due to the fact that fire originates from human activities or equipment installed within buildings, it is possible to directly influence the potential effects on the building by reducing the rate of fire starts and providing measures to directly limit fire severity.The design of buildings for fire safety is mostly achieved by following the prescriptive requirements of building codes such as the BCA. For situations that fall outside of the scope of such regulations, or where proposed designs are not in accordance with the prescriptive requirements, it is possible to undertake performance-based fire engineering designs.However,。

NATURE AND MODERNISM IN CONTEMPORARY FINNISH ARCHITECTURE 当代芬兰建筑中的自然和现代主义Juhana Lahti(尤哈得·拉赫蒂)Fin nish architecture is renowned primarily for two things: pragmatic and no-nonsense modernism and a mythical relationship with nature. This has been the case ever since Alvar Aalto and his contemporaries, including Erik Bryggman and Pauli E. Blomstedt, designed the first masterpieces of Finnish modern architecture some 80 years ago. Aalto's 1930s designs, especially the Paimio Sanatorium completed in 1933, Bryggman's private houses and blocks of flats in the city of Turku, and Blomstedt's church designs, most importantly the Kannonkoski Church completed in 1938, mark the early stage of Finnish modern architecture.Modernism has subsequently been the movement that the mainstream, and often also the alternative, Finnish architecture has learned on. The commitment to modernism is related to Finland's social development since it gained independence in 1917 and the Nordic approach to architecture and design.Northern Location and CultureIn the Nordic variety of modernism, the architecture is interwoven with many Northern European cultural traits. The determining factors at play are climate and natural surroundings, but also a communal spirit, drawing on Lutheranism, which has been embodied by the Nordic welfare state. A key characteristic in the formation of the local people's relationship with nature, which is worth mentioning here, is the idea of "freedom to roam", which, in a nutshell, means that everyone has the right to access the natural environment and what it offers, within certain limits. This tradition, which is known globally by people who live in close connection with nature, has stood its ground in the Nordic countries.The natural environment in the Baltic Sea region is very rich, varied and small in scale. The inland, again, features an endless number of lakes that form vast waterways. Finland is known as the land of a thousand lakes. In fact, you can say that Finnish nature is filled with unique places. We do not have endless sandy beaches by oceans or particularly great differences in height. Instead, we have rivers, lakes and archipelagos. This varied and omnipresent alternation of land and water provides arhythm to the Finnish natural landscape. This rhythm is both visual and spatial. In addition, the changing of the four seasons, with warm and light summers and dark, snowy and cold winters when the waterways freeze, accentuates the variability of he landscape and has a considerable effect on the use of natural space.On Finnish ArchitectureI see that all the above is closely associated with what people perceive as good architecture in Finland. Being tied to a site or place and spatial experience are key issues here.Firstly, what is considered good architecture is linked with having respect for a site and its history, whether in a natural or an urban setting. The leading Finnish architects from the 1930s to the 1960s, most importantly Alvar Aalto, consistently insisted that the trees on building sites were to be protected against damage throughout the projects. This was a way to allow nature to be a concrete part of the buildings’ yard areas. During this era, zone thinking became part of urban planning, and the link between residential areas and natural green zones assumed particular prominence in suburban planning. In urban planning, having an appreciation for historic building stock is a phenomenon of recent decades. As a flip side to the development of modernisation, the 1970s still saw numerous historic wooden buildings pulled down in practically all Finnish cities. The demolition frenzy has since subsided, although things have not changed completely. Over the decades, modern architecture, too, has been accepted as part of our built heritage. Similarly, historic urban environments are now considered worth preserving. In Finland, there are no cases of vertical expansion of historic buildings, as, for example, in Tallinn, the capital of Estonia, Finland's southern neighbour. A revealing example of the situation is the controversy over the Cloud City design by ALA Architects, which is presented in this magazine.Secondly, it is linked with viewing a building's immediate surroundings as its expansion and an integral part of the overall architectural design. The entry into a building and the views from inside are a particularly important part of the architecture and the way it is experienced. Allowing natural light into a building, an idea prevalent in modern architecture, was enthusiastically welcomed at our northern latitudes, where there are precious few hours of sunlight in the wintertime. Placing special emphasis on a site or place, which I mentioned above, is closely related to architectural character. The carefully thought-out views that open onto the building's surroundings tie it to the site andthe surrounding nature to the architectural design. A well-known example of this is the Otaniemi Chapel by Heikki Siren and Kaija Siren, completed in 1957. The approach to and exit from a building play an important role in creating a spatial experience. A case in point is the Chapel of St. Lawrence designed by Avanto Architects. Located in a historical setting, the essence of the chapel design is the movement towards the building, into it and back out of it into the churchyard.Thirdly, it includes the ideal of low-density living, which is related to the fact that Finland is a very sparsely populated country. In this respect, the Finnish architectural culture in urban planning differs considerably from the situation in international metropolises or other densely populated areas. How this ideal is realised in today's .increasingly dense urban environment is arguable, but Finns still value natural environments as part of their cities and remain sceptical about high-rise buildings. The appreciation of natural environments shows, for example, in the“ forest suburbs” built in the 1950s in the Helsinki region. One of these is Tapiola, in which fairly low blocks of flats sit amidst trees, laid out according to the contours of the terrain and without fences separating the plots. High-rise construction is presently a topic of lively discussion in the Helsinki region, and the Cloud City project is one example of this. The arguments against high-rises include the preservation of historic urban spaces and the importance of natural light: people do not want tall buildings to rise above the current skyline for fear of changing the cityscape and overshadowing the rest of the city, especially in the winter, when the sun barely rises above the horizon.The Significance of Public BuildingsVarious public buildings are importantly linked to the welfare state services, which encompass public health care, public libraries, the education system and the state church. Most Finns are members of the Lutheran church. In the Lutheran tradition of Christianity, church buildings feature little ornamentation and hey are mostly used for silent worship. Chapels are smaller buildings that are designed for funeral ceremonies. The more recent religious buildings highlight communality, nature as a visual element, and traditional building methods. The Chapel of St. Lawrence by Avanto Architects is a fine example of how the heritage of modern architecture has been updated to meet contemporary needs. The elegant and unique material choices and lighting solutions perfect this Hirvilammiarchitectural work of art, which at the same time takes its place in the chain of modern Finnish chapel buildings, including the Resurrection Chapel by ErikBryggman (1941) and the Chapel of the Holy Cross by Pekka Pitkänen (1967), which form a pair on the same cemetery site in the city of Turku.The heritage of modern architecture is also shown in the St. Henry's Ecumenical Art Chapel in Hirvensalo by Sanaksenaho Architects (2005) and the Kuokkala Church in Jyväskyläby Lassila Hirvilammi Architects (2009). The interior solutions of these projects demonstrate the architects' familiarity with the designs of the Salla Church by Eero Eerikäinen and Osmo Sipari (1950) and the Vatiala Chapel in Kangasala by Viljo Revell (1960).Schools and nurseries are another example of architecture designed for communities. The current Finnish education system is among the best in the world and is perhaps the greatest achievement of the Finnish welfare state. Everyone is given equal opportunities in education, starting from the nursery. The education system also plays a role in maintaining cultural cohesion in Finland. The design of comfortable facilities that support teaching has a strong tradition. School playgrounds are considered to be part of the overall design, which is especially important with nurseries, as playing games outside is a significant part of the childdren's day. Safe playgrounds should therefore an integral part of buildings for children. Fine examples of designs in this category are the Kirkkojärvi School by Verstas Architects (2010) and the Saunalahti Children's House by JKMM Architects (2011), both located in Helsinki's neighbouring city of Espoo.The Ideal of Modest LivingHaving a long-lasting tradition of a democratic society shows in housing forms and ideals. Making high-quality housing available for everyone has been at the core of the Nordic welfare state ideology. A case in point is the small and low-rent student flats. Often, some of the best architects are hired for the design of student housing, and projects are subject to architectural competition. This was the case with the HOAS student housing unit in Viikki by Playa architects (2010), which was inspired by the 1950s Nordic residential architecture, and the HOAS student housing unit at Intiankatu 20 in Kumpula by Brunow & Maunula (2007), which is designed to function as a quiet pocket in a noisy urban setting.From another angle, the democratic tradition and the, as yet, natural relationship between people and their environment is linked to the tradition of summer residences, with which most Finns are familiar. The tradition is also closely related to our natural landscape, which, as I mentioned above,is seen to contain countless places. A noteworthy example of summer residences designed to beavailable to all are the summer cottages that are located on rented plots in public recreation areas and that were originally designed for the underprivileged. This is an interesting extension to the right of freedom to roam, and there are thousands of summer cottages like these in Helsinki alone. At the start of the 21st century, this tradition is enjoying a revival, as new generations of city residents have discovered it. The City Cottage in Lauttasaari by Verstas Architects (2010) is a superb update of the traditional concept. The summer cottages are sought after and new areas to accommodate them are being planned. As an example, summer cottage areas are included in the plan of Kruunuvuorenranta, a forthcoming new residential area in eastern Helsinki Many of the projects presented in this magazine reflect the characteristics mentioned above. A large number of them have been realised as a result of architectural competitions. The practice of architectural competitions has a long tradition that goes back to the late 19th century. Competitions are an effective way of finding the best possible solution but they also serve as a manifestation of our democratic culture, as everyone gets an opportunity to showcase their skills. In this article, I have highlighted specific projects to illustrate in more detail the issues discussed. The projects relate to the forms of housing and the design of communal spaces, in which traditions and exciting contemporary solutions meet in a way that is characteristic of Finnish architecture. Moreover, they all, to a greater or lesser extent, exhibit an awareness of the tradition o f Nordic modern architecture, and they do so with pride and respect. □1 内容1.1内容芬兰建筑主要因两点而闻名:实用而直接的现代主义和一种同自然之间的虚构的关系。

英语原文A Unified Approach to Project ManagementThomas Froese* and Sheryl Staub-French**Dept. of Civil Engineering, Univ. of British Columbia, Vancouver, BC, Canada, V6T 1Z4. e-mail: 1tfroese@civil.ubc.ca, 2sherylsf@civil.ubc.caAbstractIn current project management practice, the overall task of designing, managing, and constructing a building is carried out by organizing the work into many distinct tasks assigned to many different groups. Most project effort is then directed towards carrying out these tasks in the most effective manner possible, while relatively little effort (concentrated within a few critical positions) is focused on managing the interdependencies between tasks and effectively combining these results to yield the overall result. We propose a unified approach to project management that brings an integrative view to the forefront, centered on the notion of defining multiple views of the project and the interrelationships that exist between the views. This integrated representation acts as a model or prototype of the physical facility, allowing more experimentation and optimization and providing a unifying focus for the ongoing work. The representational framework, proposed methodology, and accompanying IT issues for this approach to project management are discussed.MotivationMuch of our previous research has been in the area of information technologies (IT) applied to the task of project management (PM) in the field of architecture, engineering, construction, and facilities management (AEC/FM). Within this field of research and development (R&D), a major theme has been the integration of information resources and tools throughout the AEC/FM project lifecycle. Great progress has been made in the concepts, technologies, and tools to support this integration. As of yet, however, the results have had minimal impact on practice in the industry. This situation begs the question of why this active area of R&D has not had greater impact. One significant problem seems to be that the resulting technologies and tools do not fit particularly well with current project management practices. More specifically, the new tools assume and require a level of integration and coordination among project participants that is seldom found in practice. Clearly, the technologies require further development towards tools that better suit current practice. Yet it may be useful to also consider current project management practices to see if changes could be introduced that would allow projects to better exploit the advances that have been made in IT.From this initial perspective of IT, we have begun to explore potential weakness and opportunities for improvement in current project management practices. In the process, the perspective has broadened to identify several issues that are not specifically IT related. These are not new concepts, but a collection of several current trends in AEC/FM and relevant ideas from other industries. In this paper, we consider several of these views on weakness in current project management practices and opportunities for improvements. We then synthesize these into a proposed framework for a unified approach to project management in AEC/FM.Perspectives on Weaknesses and Opportunities for Project ManagementComplexity and Interdependencies in AEC/FM projects. AEC/FM projects are often described as large and increasingly complex. A greater understanding of the nature of this complexity can point to the areas where the need for improved management is greatest.Studies have identified the following characteristics as generally common to anytype of complex system11:plex systems are comprised of a multiplicity of things; they have a large number of entitiesor parts. Generally, the more parts a system contains, the more complex it is.plex systems contain a dense web of causal connections among their components. The partsaffect each other in many ways.plex systems exhibit interdependence of their components. The behavior of parts isdependant upon other parts. If the system is broken apart, the components no longer function 1Paraphrased from Homer-Dixon 2001, pp.110-114.(like the parts of the human body).plex systems are open to their outside environments. They are not selfcontained, but areaffected by outside events.plex systems normally show a high degree of synergy among their components: the wholeis more than the sum of its parts.plex systems exhibit non-linear behavior. A change in the system can produce an effect thatis not proportional to its size: small changes can produce large effects, and large changes can produce small effects.To some extent, all of these features can be observed in AEC/FM projects. AEC/FM projects are made up of components such as the physical elements in a building, thedesign or construction activities, the people and resources utilized, etc. In many cases, the individual components are not complex. Yet the number of components that make up the project is vast, and the causal connections between these components are numerous. For example, a change in the intended use of some space in a building could affect the heating and cooling requirements for that space, which could affect the design of parts of the mechanical system, which could alter the elements of the electrical system, which could change a purchase order for material supplies, which could delay a material delivery, which could influence the construction schedule, which could reduce the productivity of a work crew, which could increase a work package cost, which could affect a sub-contractor’s financing, and so on.AEC/FM projects, then, are justifiably described as complex, largely because of the quantity and interdependence of the components that make up the project.Explicit recognition of interdependency in project management approaches.One of the fundamental mechanisms that the AEC/FM industry has developed for dealing with complexity is the approach of dividing project work into well-defined work tasks and assigning each work task to a specialist group. These tasks are then carried out, to a large extent, as if they are fairly independent from each other. To be sure, each participant has some notion that their work must follow certain work and must precede other work, and that certain actions or outcomes of their work will influence others. By and large, however, participants focus primarily on their individual tasks, with any concerns about these interdependencies addressed in a very ad hoc and reactive way. Most participants try to optimize their own work while the few people responsible for managing the project as a whole have little opportunity to optimize the entire system.Clearly, it is beneficial to organize work in such a way as to minimize interdependency among work tasks. However, we contend that a weakness of current project management practice is that it tends to treat typical AEC/FM work tasks as being far more independent than they actually are. Instead, project management approaches should strive to make the interdependencies between work tasks more explicit. This does not increase interdependence and complexity, but it does make the existing interdependency and complexity more visible, and therefore more manageable. In summary, AEC/FM projects are complex because of the quantity and interdependency of their components, and project management techniques should strive to make these interdependencies explicit.Information, Information Management, and Information Technology. All design and management tasks on AEC/FM projects are fundamentally information processing tasks: they take existing project information as input and produce new project information as output. Even construction tasks, which deal with the processing of physical resources, require information as a significant resource. Yet the information resources and information flows are rarely considered and managed explicitly, and are instead treated as implicit in assigned work tasks and physical project components. This makes the management of this important resource haphazard, and makes the application of appropriate information technology more difficult.Information Management. We suggest the following general approach to information management (IM) on AEC/FM projects. The IM should adopt a processbased approach, organizing the project into its work tasks. The IM approach should then consider three main issues: 1) the information requirements for each task, 2) the communication requirements between tasks, and 3) the integration across tasks and communications. For each task, the IM should evaluate what the information input requirements are, what IT tools should be used for supporting the task, and what the information outputs are. For communications, the IM should evaluate what information flows must exist between tasks (including their required characteristics such as sender, receiver, mode, content, etc.), and what information and communication technologies are used for these communications. For the integrative analysis, the IM should examine the integration across all tasks and communication flows (i.e., adopt a holistic view and common IT platforms, rather than addressing each task or communication flow in isolation). This includes integration across organizational boundaries and integration with existing (and future)technologies.Disparate views of a project.As stated previously, all design and management tasks work with information rather than physical resources. This information all describes or models the physical construction project, and thus it can be said that all designers and managers work with information models of the project. However, each task often works with its own unique view, perspective, or type of information model. This wide range of disparate views adds to the fragmentation of these tasks. There is very little of a common, shared vision of the project across all participants—at least until the physical structure begins to emerge, which provides a unifying common perspective for all participants.A unified IT view. One of the opportunities of emerging IT is the ability to create building information models: semantically rich information models of construction projects that include both 3D geometric information (3D CAD) along with nongeometric information (everything from material properties to construction costs and schedules). These models support a wide range of advanced analytical and predictive software tools, including virtual project representations such as photo-realistic 3D renderings and walk-throughs, and they support extensive information sharing and software interoperability throughout the lifecycle of the project (as exemplified by the Industry Foundation Classes, IFCs, see International Alliance, 2002 and BLIS, 2002). This technology does not require that all project information be combined into a single model, but it allows linkages and interoperability between the various bodies of project information.This technology offers opportunities to create a more unified approach to project management in two ways. First, by linking together disparate views of project information and supporting software interoperability, it provides a technical platform for achieving a more integrated approach to project management. Second, the “virtual building” created by these technologies has the potential of acting as a common focal point, or unifying view, for all project participants, particularly during pre-construction design and management phases, much in the way that the physical structure does during the construction phase.Lean Construction and Workflows. There is currently a great deal of attention being paid to the area of lean construction, which spans a wide range of issues that relate to the management of AEC/FM projects (Lean Construction Institute, 2002). Among these issues is the concept that when a project is made up of many interdependent tasks, a focus on optimizing each task independently leads to sub-optimization of the overall project. Therefore, project management practices should ensure that tasks are managed with careful consideration of their role within the overall project workflows; they should not be treated as isolated, independent activities.Software Engineering and the Unified Modeling Language. Although project management has a much longer (and perhaps more successful) history within the field of AEC/FM than in the field of software engineering, there are some valuable lessons that AEC/FM can learn from developments in the software industry, particularly related to integrated information structures for managing projects.Much of the software engineering community has consolidated around the Unified Modeling Language (UML) (Object Management Group, 2002), a standard language for representing the components involved in the design and implementation of software projects. The UML provides a much more uniform and integrated (if less comprehensive) view of project requirements, processes, and elements, than comparable representations within AEC/FM (i.e., project plans and specifications, construction schedules, etc.).Furthermore, UML-based software development methodologies have emerged (e.g., the Unified Process, Kendall, 2002) that tightly integrate the various project workflows with the various project artifacts (deliverables) throughout each phase of the project lifecycle. These methodologies also accentuate the cyclical and repetitive nature of the related work tasks that are carried out within workflows as they move through the phases of the project lifecycle. Unlike approaches that treat each activity as an independent, one-time task, this reinforces attempts to continually improve performance in this work. While these techniques are not directly applicable to the AEC/FM industry, some of the approaches and best practices are quite relevant.A Unified Approach to Project ManagementWe have argued that existing project management practices underemphasize the interrelationships between individual work tasks and other project components. This leaves the interdependencies under-recognized and under-managed, and promotes a “one-time event” thinking that hinders the quest for ongoing performance improvements. We have begun to conceptualize a unified approach to project management that addresses some of the weaknesses and opportunities identified above.The basic approach is to adopt a framework that: 1) explicitly represents the various views that are critical for managing projects, and 2) explicitly represents the interconnections between these views.Examples of project views include the physical view (“what”), the process view (“how, who, when”), the cost view (“how much”), etc. (Russell and Froese, 1997). If the total collection of project information is thought of as a multi-dimensional information space, then the views define the dimensions. For each view, the overall project can be broken down into smallerelements. The simplest representation of a view would be a list or hierarchical breakdown structure of the elements that make up the view (e.g., a work breakdown structure, WBS). More complex representations would capture additional relationships between the elements, such as a CPM network or an IFC model.Primary Views. There are many views that can be useful for managing projects. To act as a unifying management tool, however, these views should be shared with all participants, and this places a practical limit on the maximum number of views, since it would become too complex to require all participants to work with numerous, interconnected views. We propose that the following three views to be used as the primary project coordination mechanism for all participants:•The project lifecycle dimension: The first primary view is time-based, organizing the project into well-defined project phases, which are further refined into iterations. These phases are arranged in sequential chronological order, constituting a logical time-view. This dimension can also provide an absolute time-view by defining the calendar dates for activities that take place within the phases. Unlike current project management practices where project phases are treated “loosely”, the phases and iterations have formal management roles. All work requirements, assignments, outputs, etc. are defined relative to a specific project phase, and phases have formal progress review procedures. This approach to phases can be seen, for example, in the Process Protocol approach (Process Protocol, 2003) and in the previouslymentioned Unified Process (Kendall, 2002).•The workflow dimension: The second primary view is process-based. It organizes the work into the various work disciplines required to complete the project. This is somewhat like the normal division of work into work packages, but rather than describing the tasks as discrete work packages, the work is organized as ongoing workflows, which can be further broken down into sequences or networks of sub tasks. Thus tasks are more explicitly placed in the context of the overall workflows than is common practice today.•The product/deliverable dimension: The third primary view organizes the outputs or deliverables of work. This view combines two important main elements, the information that describes the construction product (facility) being created, and the physical product itself.During the early phases of the project, the deliverables of design and management tasks are information about the physical facility. The collective sum of all of this information can be thought of as the building information model or virtual building (whether or not an integrated IT environment is used). During later phases, this information drives the physical deliverables of the construction work: the creation of the physical components themselves. This view emphasizes a continuum that flows from the virtual facility to the physical one.As a highly simplified example, an AEC project might be organized into the following primary views:Project Lifecycle Dimension:⏹Inception Phase⏹Design Phase⏹Construction Phase⏹Operation PhaseWorkflow Dimension:⏹Architectural workflow⏹Structural workflow⏹Building Services workflow⏹Cost workflowProduct/Deliverable Dimension:⏹IFC Product Model⏹Project Documents⏹Building Superstructure⏹Building Systems and FinishesIntegrating and Representing the Primary Views. Given these three primary dimensions, the work can be further organized by expressing the interrelationships between the dimensions:●Workflows vs. project lifecycle: Placing workflows and their constituent tasks within projectlifecycle phases creates a schedule view of the project, showing what should happen when.This can include both the logical schedule (sequencing) and absolute schedule (calendar dates). It can also show that most workflows span multiple phases/iterations, and can indicate the amount of effort expended on each workflow over time, which emphasizes the “ongoing processes” nature of the work.●Product/deliverables vs. project lifecycle: Similarly, the various project deliverables can bemapped to the project phases/iterations. The deliverables are generally cumulative, thus this shows how the total project output (the collective body of project information and the physical structure) develops over time.●Product/deliverables vs. workflows: The assignment of project deliverables to workflows andtasks shows how work processes collaborate to produce the required deliverables.The definition of the three primary views and the interrelationships between them defines a three-dimensional space, as illustrated in Figure 1. Key to the applicability of this approach is the ability to represent the primary views and their interrelationships in a simple, intuitive manner that all project participants can work with. It would be ideal if this could be achieved in a single, three-dimensions format, but it seems unlikely that such a representation is possible (even the simplified representation in figure 1 shows the relationships of each pair of dimensions rather than the relationships between all three dimensions simultaneously). Therefore, it may be necessary to represent the primary dimensions as a set of two-dimensional matrices. Each of these matrices may be quite simple and intuitive. For example, the matrix of workflows vs. project lifecycle forms a Gantt chart (bar chart schedule). What is essential (and what would differentiate this approach from current practice) is that the collection of two-dimensional matrices is interrelated and kept synchronized, which would require an effective underlying project management tool.Figure 1: Schematic of the dimensions in a unified approach to project management. Additional Views. We have suggested that the three primary views seem to be appropriate for the overall project organization and the coordination of all participants. However, those responsible for managing the project can add several more interrelated views. This would provide a very powerful representation of the project from all of the perspectives that are important for achieving project objectives, along with explicit representations of the interrelationships that exist between these views. Examples of the additional views include the following:●Organization View: An organizational view identifies the project participants; can link participantsto workflows/tasks, deliverables, etc.●Cost View: This view identifies the various cost schedules (estimates, costcontrol accounts, etc.)that are important to the project. Costs can be related to workflows/tasks, deliverables, organizational units, etc.●Risk View: As part of a risk management approach, significant risks can be identified andassociated with specific workflows/tasks, deliverables, organizational units, cost items, etc.●Quality View: Quality management programs may identify quality metrics, inspection tasks andresults, etc., associated with the workflow/tasks and deliverables.●Requirements View: Software engineering methods formally capture system requirements usingconstructs such as use cases. On AEC/FM projects, requirements would typically be less structured, but it may be possible to define a view that explicitly represents the project requirements in a way that helps●As-Built View: As construction work proceeds, the actual results of the work, in terms of finalconstruction results, actual cost and productivity data, etc., can be captured in an as-built view.●Other Views: A view can be created for any other area of interest on a project where a set of itemscan meaningfully be identified that relate to other defined view, such as a contractual view, safety view, environmental impact/sustainability view, punch list/defect view, maintenance view, etc.The possibility of defining a large number of views does not imply that a significant amount of additional management work is required. Rather, it suggests that when issues are already being addressed with some form of explicit management effort, that a representation structure can be used that can capture the relationships with other management issues.In many cases, the relationships between any two views may form a narrowly banded matrix: each item in one view would be associated with a small number of items in the other view. This may lead to interesting possibilities, such as the ability to partially automate the creation of one view from another (e.g., automatic generation of approximate lists of construction activities and estimate items from a building product mo del), or the ability to recognize “exceptions”, cases where relationships deserve extra management attention because they lie outside of the typical band of inter-relationships. Changing the Project Mindset.The unified approach to project management involves not only a change to the representational structures as outlined above, but this also a change in the way participants think of the underlying project mechanism and their role in it. Currently, projects are regarded as custom, unique endeavors and project tasks as a collection of one-off activities. The thought process is to find a satisfactory solution to the project requirements rather than to find “the best” solution. In part, this is because there is no room for trial-and-error exploration. Full-scale models are impossible and small-scale physical models are of limited use.In the unified approach to project management, the integrated project representations acts as project prototypes or models that can play the same centralrole in construction as prototypes do in manufacturing. They provide integrated, computer-based collections of all known project information. They may contain geometric information to allow tools like 3D visualization, but they also contain nongeometric design and management information, such as material properties, supplier information, cost and schedule data, organizational information, etc. Thus, the perspective is changed to be more like that of manufacturing: a prototyping process followed by an ongoing production process. Design and planning tasks first work towards the creation of prototypes or models. In these models, alternatives are developed and explored, new issues are identified and resolved, and interactions and interfaces are hammered out. Once all concerns are satisfied, the prototype is used to organize the production process. Every participant views their role as carrying out their tasks by drawing information from the project model, placing their results back into the project model, and using the model to explore the interaction of their work with others and to support communications. In this way, the overall concerns of the project are more prominent to all and are easier to identify and explore—we believe this will produce better solutions.Working with the Unified Approach to Project Management.As shown, the unified approach to project management is based on defining formalized views of project information along with the interrelationships between the views. This section will discuss how this approach might be carried out by comparing it with best practices in how project scheduling is carried out. If good scheduling and schedule control practices are used on an AEC/FM project, the project will benefit from good work coordination; there will be more certainty about the timing of events; it will be easier to measure progress; and productivity, cost, and project duration will be improved. Similarly, good practices using the unified approach will improve the project outcomes through more effective planning, particularly with respect to the interdependencies between project views. The process would be approximately as follows:●The project management team would define the project views to be used on the project.●Project planning would be carried out much as on a typical project, except that the results would berepresented using the defined project views. This would result in lists or breakdown structures for the project phases, workflows/tasks,deliverables, etc. This would be analogous to a typical project scheduling process, where the results are represented in a CPM network.●The key inter-relationships between the views would be defined. This would be analogous to theway that precedence relationships are captured in a schedule, or the way that a schedule can bemapped to cost accounts, resource plans, or to a building information model (as in the case of 4D CAD). Other than the precedence relationships, this type of mapping is not typically done in current project management practices, so it represents some additional work for project planners.However, it need not be done at a very detailed level, and the use of hierarchical relationships and effective planning tools may minimize the effort required for this task.●The execution of the resulting plan (e.g., initiating work tasks), project controland feedback(collecting progress information and monitoring results), and replanning activities all take place using the representational framework. Work tasks themselves remain essentially unchanged, but because the planning and management system explicitly captures the interrelationships, the causal links between actions will be better recognized and understood, and the potential negative impacts of any action will be identified earlier and mitigated or avoided more easily. For example, in the case of the change in the intended use of some space in a building mentioned previously, the threads of the causal impacts of this change may be more easily traced through the design,construction, procurement, time, and financial aspects of the project—appropriate adjustments can be made in advance, rather than allowing the impact to propagate as a series of unanticipated, reactionary actions.●As with scheduling, detail is important, but not all detail is required in advance. Planning for eachview might be carried out at a summary level initially, with greater detail added over time, culminating in something like detailed, rolling two-week look-ahead unified plans.●In scheduling, basic schedule representations such as bar charts are widely used as coordinationmechanisms for all participants, while more advanced analysis like resource leveling is carried out by project management specialists only. Similarly, the many potential applications of the unified approach fall into three general categories: 1) the use of the primary views as a broadly-applicable coordination mechanism shared by all participants, 2) the use of multiple views to capture all of the detailed information relevant to one participant carrying out one particular task, and 3) the use of detailed information in multiple views to carry out some specialized project analysis.We have discussed the unified approach to project management in terms of a representational framework and general methodology for project planning and management. However, the organizational context for the approach should also be addressed. This would include issues such as how the project team is organized (ideally, all key team members would be involved early in the process); who carries out which portions of the unified plans, when, and in how much detail; how incentives are structured to encourage effective use of the unified approach, etc. The approach is also quite dependant on a set of appropriate IT tools to support the process, as discussed in the following section.IT Tools to Support the Unified Approach to Project Management. A practical minimum requirement for applying the unified approach to project management is some type of IT platform that allows the views to be represented, inter-related, accessed, and utilized in an efficient manner by all project participants. Such asystem would be similar in many ways to various systems in common use today—project scheduling software, project management systems such as Prolog Manager from Meridian Project Systems, and web-based project collaboration systems such as Buzzsaw from Autodesk—yet none of these existing systems capture all of the multidimensional and integrated nature of the proposed approach.The unified approach would be an excellent complement to IT systems that use integrated product and process models, such as those based on the IFC’s, but these are not a necessary requirement for using the approach. Finally, while the minimum requirements for an IT platform would be the support of information entry and access (e.g., database-type functionality), it would also be possible to operationalize the integrated models. This could provide simulation, analysis, and visualization, e.g., as is done for certain views by scheduling software, 4D CAD systems (Fischer and Lam, 2002) or organizational simulation (Levitt, 2003). The representation of work activities in the system could also tie into workflow management systems to partially automate the management of the project activity. Thus, the problem of fit between project management practices and emerging IT technologies would be addressed in two ways. First, it creates explicit linkages between the project management framework and integrated IT systems. Second, and perhaps more importantly, it strongly emphasizes the integration and collaboration of all project activities, which is a basic requirement of highly integrated and interoperable IT approaches.ConclusionsIn summary, we have presented several perspectives of project management practices that suggest weakness with current practice and opportunities for improvement. We have synthesized these into a unified approach to project management, which is based on an explicit representation of multiple project。

The affordability of housing affects the ability of the elderly to afford other necessities of life such as food and medical care. Housing that is located near hospitals and doctors, shopping, transportation, and recreational facilities can facilitate access to services that can enhance the quality of life. Housing can also be a place of memories of the past and a connection to friends and neighbors. Housing with supportive features and access to services can also make it possible for persons to age in place. In this session, we will be examining housing problems andoptions for the elderly. Along the way, we will be testing your housing IQ with a series of questions and exercises.2. Housing Situation of Older PersonsHow typical is the housing situation of the olders?We will begin by examining five areas :(1)Prevalence of home ownership (2)Length of stay in current residence (3)Living arrangements (4)Attachments of older persons to where they live (5)Moving behavior.With whom older persons live can influence housing affordability, space needs, and the ability to age in place. About 54% of older persons live with their spouses, 31% live alone, almost 13% live with related persons other than their spouse and about 2% live with unrelated persons. With increasing age, older persons (primarily women) are more likely to live alone or with a relative other than a spouse. Frail older women living alone are the persons most likely to reside in homes with ‘extra’ rooms and to need both physically supportive housing features and services to "age in place". This segment of the population is also the group most likely to move to more supportive housing settings such as assisted living.Many older persons have strong psychological attachments to their homes related to length of residence. The home often represents the place where they raised their children and a lifetime of memories. It is also a connection to an array of familiar persons such as neighbors and shopkeepers as well as near by places including houses of worship, libraries and community services. For manyolder persons, the home is an extension of their own personalities which is found in the furnishings . In addition, the home can represent a sense of economic security for the future, especially for homeowners who have paid off their mortgages. For owners, the home is usually their most valuable financial asset. The home also symbolizes a sense of independence in that the resident is able to live on his or her own. For these types of reasons, it is understandable that in response to a question about housing preferences, AARP surveys of older persons continue to find that approximately 80% of older persons report that what they want is to "stay in their own homes and never move." This phenomena has been termed the preference to "age in place."Although most older persons move near their current communities, some seek retirement communities in places with warmer weather in the southwest, far west and the south.3. The Federal Government's Housing Programs for the ElderlyThe federal government has had two basic housing strategies to address housing problems of the elderly. One strategy, termed the "supply side" approach, seeks to build new housing complexes such as public housing and Section 202 housing for older persons. Public housing is administered by quasi-governmental local public housing authorities. Section 202 Housing for the elderly and disabled is sponsored by non-profit organizations including religious and non-sectarian organizations. Approximately 1.5 million olderpersons or 3% of the elderly population live in federally assisted housing, with about 387,000 living in Section 202 housing. Over time, the government has shifted away from such new construction programs because of the cost of such housing, the problems that a number of non-elderly housing programs have experienced, and a philosophy that the government should no longer be directly involved with the building of housing. Section 202 housing, a very popular and successful program, is one of the few supply-side programs funded by the federal government, although the budget allocation during the last ten years has allowed for the construction of only about 6,000 units per year compared to a high of almost 20,000 units in the late 1970s. Instead of funding new construction, federal housing initiatives over the last decade have emphasized ‘demand side’ subsidies that provide low-income renters with a certificate or a voucher that they can use in a variety of multiunit settings, including apartments in the private sector that meet rental and condition guidelines. These vouchers and certificates are aimed at reducing excessive housing costs. Some certificates are termed ‘project based’ subsidies and are tied to federally subsidized housing such as Section 202. Because housing programs are not an entitlement, however, supply-side and demand side programs together are only able to meet the needs of about 1/3 of elderly renters who qualify on the basis of income.While advocates for housing have been trying to hold on to the existing programs in the face of huge budget cuts at HUD, much of the attention has been shifting towards meeting the shelter and service needs of the frail elderly. This emphasis reflects the increasing number of older persons in their eightiesand nineties who need a physically supportive environment linked with services. This group of older persons includes a high percentage of older residents of public and Section 202 housing. Initially built for independent older persons who were initially in the late sixties and early seventies, this type of housing now includes older persons in their eighties and nineties, many of whom have aged in place. Consequently, the government is faced with creating strategies to bring services into these buildings and retrofit them to better suit the needs of frail older persons. A major initiative of the early 1990s, which may be stalled by current budget problems at HUD, has been for the federal government to pay for service coordinators to assess the needs of residents of government assisted housing complexes and link them with services. As of 1998, there were approximately 1,000 service coordinators attached to government assisted housing complexes across the country.4. The Housing Continuum: A Range of Options for ElderlyA long-standing assumption in the field of housing has been that as persons become more frail, they will have to move along a housing continuum from one setting to another. As the figure on housing options suggests, along this continuum are found a range of housing options including single family homes, apartments, congregate living, assisted living, and board and care homes (Kendig & Pynoos, 1996). The end point of the housing continuum has been thenursing home. These options vary considerably in terms of their availability, affordability, and ability to meet the needs of very frail older persons.The concept of a continuum of supportive care is based on the assumption that housing options can be differentiated by the amount and types of services offered; the supportiveness of the physical setting in terms of accessibility, features, and design; and the competency level of the persons to whom the housing is targeted. The figure on housing options indicates how such options generally meet the needs of older persons who are categorized,as independent, semi-dependent and dependent. Semi-dependent older persons can be thought of as needing some assistance from other persons with instrumental activities of daily living (IADLs) such as cooking, cleaning, and shopping. In addition to needing assistance with some IADLs, dependent older persons may require assistance with more basic activities such as toileting, eating and bathing. Although semi-dependent and dependent older persons can be found throughout the housing continuum, independent older persons are very unlikely to reside in housing types such as assisted living specifically designed and equipped to meet the needs of frail older persons unless their spouses require these needs.Although the continuum of housing identifies a range of housing types, there is increasing recognition that frail older persons do not necessarily have to move from one setting to another if they need assistance. Semi-dependent or dependent older persons can live in a variety of settings, including their own homes and apartments, if the physical environment is made more supportive, caregivers are available to provide assistance and affordable services areaccessible.5. ConclusionsHousing plays a critical role in the lives of older persons. Most older homeowners who function independently express a high level of satisfaction with their dwelling units. However, high housing costs, especially for renters, remain a financial burden for many older persons and problems associated with housing condition persist especially for low- income renters and persons living in rural areas. Federal housing programs such as public housing, Section 202 housing, and Section 8 housing certificates have only been able to address the basic housing problems of only about one-third of eligible older persons because of limited budgets. Moreover, a shortage of viable residential options exists for frail older persons. Up until the last decade, housing for the elderly was conceived of primarily as shelter. It has become increasingly recognized that frail older persons who needed services and physically supportive features often had to move from their homes or apartments to settings such as board and care or nursing homes to receive assistance. Over time, however, the concept of a variety of housing types that can be linked has replaced the original idea of the continuum of housing. It is possible for frail older persons to live in a variety of existing residential settings, including their own homes and apartments with the addition of services and home modifications. Consequently, the last decade has seen a number of efforts to modify homes, add service coordinators to multi-unit housing and create options such as accessory and ECHO units. Although thesestrategies have been enhanced by a somewhat greater availability of home care services, Medicaid policy still provides incentives to house frail older persons in nursing homes. The most visible development in the field of housing for frail older persons has been the growth of private sector assisted living which is now viewed by many state governments as a residential alternative to nursing homes. The AL movement itself has raised a number of regulatory and financing issues that cross-cut housing and long term care such as what constitutes a residential environment, insuring that residents can age in place, accommodating resident preferences, protecting the rights of individuals and insuring quality of care. Nevertheless, the emergence of AL along with a wider range of other housing options holds out the promise that older persons will have a larger range of choices among living arrangements.译文:老年人的住宅问题与选择一、简介住宅在老年人生活的极为重要。

Architecture in a Climate of ChangePage52-Page62Low energy techniques for housingIt would appear that,for the industrialised countries,the best chance of rescue lies with the built environment because buildings in use or in the course of erection are the biggest single indirect source of carbon emissions generated by burning fossil fuels,accounting for over 50 per cent of total emissions.If you add the transport costs generated by buildings the UK government estimate is 75 per cent.It is the built environment which is the sector that can most easily accommodate fairly rapid change without pain.In fact,upgrading buildings, especially the lower end of the housing stock,creates a cluster of interlocking virtuous circles. Construction systemsHaving considered the challenge presented by global warming and the opportunities to generate fossil-free energy,it is now time to consider how the demand side of the energy equation can respond to that challenge.The built environment is the greatest sectoral consumer of energy and,within that sector,housing is in pole position accounting for 28 per cent of all UK carbon dioxide (CO2) emissions.In the UK housing has traditionally been of masonry and since the early 1920s this has largely been of cavity construction.The purpose was to ensure that a saturated external leaf would have no physical contact with the inner leaf apart from wall ties and that water would be discharged through weep holes at the damp-proof course level.Since the introduction of thermal regulations,initially deemed necessary to conserve energy rather than the planet,it has been common practice to introduce insulation into the cavity.For a long time it was mandatory to preserve a space within the cavity and a long rearguard battle was fought by the traditionalists to preserve this‘sacred space’.Defeat was finally conceded when some extensive research by the Building Research Establishment found that there was no greater risk of damp penetration with filled cavities and in fact damp through condensation was reduced.Solid masonry walls with external insulation are common practice in continental Europe and are beginning to make an appearance in the UK.In Cornwall the Penwith Housing Association has built apartments of this construction on the sea front, perhaps the most challenging of situations.The advantages of masonry construction are:● It is a tried and tested technology familiar to house building companies of all sizes.● It is durable and generally risk free as regards catastrophic failure–though not entirely.A few years ago the entire outer leaf of a university building in Plymouth collapsed due to the fact that the wall ties had corroded.● Exposed brickwork is a low maintenance system; maintenance demands rise considerably if it receives a rendered finish.● From the energy efficiency point of view,masonry homes have a relatively high thermal mass which is considerably improved if there are high density masonryinternal walls and concrete floors.Framed constructionVolume house builders are increasingly resorting to timber-framed construction with a brick outer skin,making them appear identical to full masonry construction.The attraction is the speed of erection especially when elements are fabricated off site. However,there is an unfortunate history behind this system due to shortcomings in quality control.This can apply to timber which has not been adequately cured or seasoned.Framed buildings need to have a vapour barrier to walls as well as roofs. With timber framing it is difficult to avoid piercing the barrier.There can also be problems achieving internal fixings.For the purist,the ultimate criticism is that it is illogical to have a framed building clad in masonry when it cries out for a panel,boarded,slate or tile hung external finish.Pressed steel frames for homes are now being vigorously promoted by the steel industry.The selling point is again speed of erection but with the added benefit of a guaranteed quality in terms of strength and durability of the material.From the energy point of view,framed buildings can accommodate high levels of insulation but have relatively poor thermal mass unless this is provided by floors and internal walls.Innovative techniquesPermanent Insulation Formwork Systems (PIFS) are beginning to make an appearance in Britain.The principle behind PIFS is the use of precision moulded interlocking hollow blocks made from an insulation material,usually expanded polystyrene.They can be rapidly assembled on site and then filled with pump grade concrete.When the concrete has set the result is a highly insulated wall ready for the installation of services and internal and exterior finishes.They can achieve a U-value as low as 0.11 W/m2K.Above three storeys the addition of steel reinforcement is necessary. The advantages of this system are:● Design flexibility; almost any plan shape is possible.● Ease and speed of erection;skill requirements are modest which is why it has proved popular with the self-build sector.Experienced erectors can achieve 5 m2 per man hour for erection and placement of concrete.● The finished product has high structural strength together with considerable thermal mass and high insulation value.Solar designPassive solar designSince the sun drives every aspect of the climate it is logical to describe the techniques adopted in buildings to take advantage of this fact as‘solar design’. The most basic response is referred to as‘passive solar design’.In this case buildings are designed to take full advantage of solar gain without any intermediate operations.Access to solar radiation is determined by a number of conditions:● the sun’s position relative to the principal facades of the building(solar altitude and azimuth);● site orientation and slope;● existing obstructions on the site;● potential for overshadowing from obstructions outside the site boundary.One of the methods by which solar access can be evaluated is the use of some form of sun chart.Most often used is the stereographic sun chart in which a series of radiating lines and concentric circles allow the position of nearby obstructions to insolation,such as other buildings,to be plotted.On the same chart a series of sun path trajectories are also drawn(usually one arc for the 21st day of each month); also marked are the times of the day.The intersection of the obstructions’outlines and the solar trajectories indicate times of transition between sunlight and shade. Normally a different chart is constructed for use at different latitudes (at about two degree intervals).Sunlight and shade patterns cast by the proposed building itself should also be considered.Graphical and computer prediction techniques may be employed as well as techniques such as the testing of physical models with a heliodon.Computer modelling of shadows cast by the sun from any position is offered by Integrated Environmental Solutions (IES) with its‘Suncast’program.This is a user-friendly program which should be well within normal undergraduate competence. The spacing between buildings is important if overshading is to be avoided during winter months when the benefit of solar heat gain reaches its peak.On sloping sites there is a critical relationship between the angle of slope and the level of overshading.For example, if overshading is to be avoided at a latitude of 50 N,rows of houses on a 10 north-facing slope must be more than twice as far apart than on 10 south-facing slope.Trees can obviously obstruct sunlight.However,if they are deciduous,they perform the dual function of permitting solar penetration during the winter whilst providing a degree of shading in the summer.Again spacing between trees and buildings is critical.Passive solar design can be divided into three broad categories:● direct gain;● indirect gain;● attached sunspace or conservatory.Each of the three categories relies in a different way on the‘greenhouse effect’as a means of absorbing and retaining heat.The greenhouse effect in buildings is that process which is mimicked by global environmental warming.In buildings,the incident solar radiation is transmitted by facade glazing to the interior where it is absorbed by the internal surfaces causing warming.However,re-emission of heat back through the glazing is blocked by the fact that the radiation is of a much longer wavelength than the incoming radiation.This is because the re-emission is from surfaces at a much lower temperature and the glazing reflects back such radiation to the interior.Direct gainDirect gain is the design technique in which one attempts to concentrate the majority of the building’s glazing on the sun-facing facade.Solar radiation is admitted directly into the space concerned.Two examples 30 years apart are the author’s housein Sheffield,designed in 1967 and the Hockerton Project of 1998 by Robert and Brenda Vale.The main design characteristics are:● Apertures through which sunlight is admitted should be on the solar side of the building, within about 30 of south for the northern hemisphere.● Windows facing west may pose a summer overheating risk.● Windows should be at least double glazed with low emissivity glass (Low E) as now required by the UK Building Regulations.● The main occupied living spaces should be located on the solar side of the building.● The floor should be of a high thermal mass to absorb the heat and provide thermal inertia,which reduces temperature fluctuations inside the building.● As regards the benefits of thermal mass,for the normal daily cycle of heat absorption and emission,it is only about the first 100 mm of thickness which is involved in the storage process.Thickness greater than this provides marginal improvements in performance but can be useful in some longer-term storage options.● In the case of solid floors,insulation should be beneath the slab.● A vapour barrier should always be on the warm side of any insulation.● Thick carpets should be avoided over the main sunlit and heatabsorbing portion of the floor if it serves as a thermal store.However,with suspended timber floors a carpet is an advantage in excluding draughts from a ventilated underfloor zone. During the day and into the evening the warmed floor should slowly release its heat, and the time period over which it happens makes it a very suitable match to domestic circumstances when the main demand for heat is in the early evening.As far as the glazing is concerned,the following features are recommended: ● Use of external shutters and/or internal insulating panels might be considered to reduce night-time heat loss.● To reduce the potential of overheating in the summer,shading may be provided by designing deep eaves or external louvres. Internal blinds are the most common technique but have the disadvantage of absorbing radiant heat thus adding to the internal temperature.● Heat reflecting or absorbing glass may be used to limit overheating.The downside is that it also reduces heat gain at times of the year when it is beneficial. ● Light shelves can help reduce summer overheating whilst improving daylight distribution.Direct gain is also possible through the glazing located between the building interior and attached sunspace or conservatory;it also takes place through upper level windows of clerestory designs.In each of these cases some consideration is required concerning the nature and position of the absorbing surfaces.In the UK climate and latitude as a general rule of thumb room depth should not be more than two and a half times the window head height and the glazing area should be between about 25 and 35 per cent of the floor area.Indirect gainIn this form of design a heat absorbing element is inserted between the incident solar radiation and the space to be heated;thus the heat is transferred in an indirectway.This often consists of a wall placed behind glazing facing towards the sun,and this thermal storage wall controls the flow of heat into the building.The main elements● High thermal mass element positioned between sun and internal spaces,the heat absorbed slowly conducts across the wall and is liberated to the interior some time later.● Materials and thickness of the wall are chosen to modify the heat flow.In homes the flow can be delayed so that it arrives in the evening matched to occupancy periods. Typical thicknesses of the thermal wall are 20–30 cm.● Glazing on the outer side of the thermal wall is used to provide some insulation against heat loss and help retain the solar gain by making use of the greenhouse effect.● The area of the thermal storage wall element should be about 15–20 per cent of the floor area of the space into which it emits heat.● In order to derive more immediate heat benefit,air can be circulated from the building through the air gap between wall and glazing and back into the room.In this modified form this element is usually referred to as a Trombe wall. Heat reflecting blinds should be inserted between the glazing and the thermal wall to limit heat build-up in summer.In countries which receive inconsistent levels of solar radiation throughout the day because of climatic factors (such as in the UK),the option to circulate air is likely to be of greater benefit than awaiting its arrival after passage through the thermal storage wall.At times of excess heat gain the system can provide alternative benefits with the air circulation vented directly to the exterior carrying away its heat,at the same time drawing in outside air to the building from cooler external spaces.Indirect gain options are often viewed as being the least aesthetically pleasing of the passive solar options,partly because of the restrictions on position and view out from remaining windows,and partly as a result of the implied dark surface finishes of the absorbing surfaces.As a result,this category of the three prime solar design technologies is not as widely used as its efficiency and effectiveness would suggest.Attached sunspace/conservatoryThis has become a popular feature in both new housing and as an addition to existing homes.It can function as an extension of living space,a solar heat store,a preheater for ventilation air or simply an adjunct greenhouse for plants.On balance it is considered that conservatories are a net contributor to global warming since they are often heated.Ideally the sunspace should be capable of being isolated from the main building to reduce heat loss in winter and excessive gain in summer.The area of glazing in the sunspace should be 20–30 per cent of the area of the room to which it is attached.The most adventurous sunspace so far encountered is in the Hockerton housing development which will feature later.Ideally the summer heat gain should be used to charge a seasonal thermal storage element to provide background warmth in winter.At the very least,air flow paths between the conservatory and the main building should be carefully controlled.Active solar thermal systemsA distinction must be drawn between passive means of utilising the thermal heat of the sun, discussed earlier,and those of a more‘active’nature Active systems take solar gain a step further than passive solar.They convert direct solar radiation into another form of energy.Solar collectors preheat water using a closed circuit calorifier.The emergence of Legionella has highlighted the need to store hot water at a temperature above 60 C which means that for most of the year in temperate climes active solar heating must be supplemented by some form of heating.Active systems are able to deliver high quality energy.However,a penalty is incurred since energy is required to control and operate the system known as the ‘parasitic energy requirement’.A further distinction is the difference between systems using the thermal heat of the sun,and systems,such as photovoltaic cells, which convert solar energy directly into electrical power.For solar energy to realise its full potential it needs to be installed on a district basis and coupled with seasonal storage.One of the largest projects is at Friedrichshafen.The heat from 5600 m2 of solar collectors on the roofs of eight housing blocks containing 570 apartments is transported to a central heating unit or substation.It is then distributed to the apartments as required.The heated living area amounts to 39 500 m2.Surplus summer heat is directed to the seasonal heat store which,in this case, is of the hot water variety capable of storing 12 000 m3.The scale of this storage facility is indicated by Figure 5.9.The heat delivery of the system amounts to 1915 MWh/year and the solar fraction is 47 per cent.The month by month ratio between solar and fossil-based energy indicates that from April to November inclusive,solar energy accounts for almost total demand,being principally domestic hot water.In places with high average temperatures and generous sunlight,active solar has considerable potential not just for heating water but also for electricity generation.This has particular relevance to less and least developed countries.环境变化影响下的建筑学房屋设计中的低能耗技术显而易见,在工业化国家,最好的营救机会依赖于建筑环境,因为不论是在使用的建筑或者是在建设的建筑,都是最大的、单一的、间接地由化石燃料的燃烧所引起的碳排放的源头,而这些站了所有排放的50%。

In the United States, 24.6 m or 7 layer above as high-rise buildings; In Japan, 31m or 8 layer and above as high-rise buildings; In Britain, to have equal to or greater than 24.3 m architecture as high-rise buildings. Since 2005 provisions in China more than 10 layers of residential buildings and more than 24 meters tall other civil building for high-rise buildings.KEYWARD:High-Rise Buildings;Shear-Wall Systems;Rigid-Frame Systems 1. High-rise building profilesAlthough the basic principles of vertical and horizontal subsystem design remain the same for low- , medium- , or high-rise buildings, when a building gets high the vertical subsystems become a controlling problem for two reasons. Higher vertical loads will require larger columns, walls, and shafts. But, more significantly, the overturning moment and the shear deflections produced by lateral forces are much larger and must be carefully provided for.The vertical subsystems in a high-rise building transmit accumulated gravity load from story to story, thus requiring larger column or wall sections to support such loading. In addition these same vertical subsystems must transmit lateral loads, such as wind or seismic loads, to the foundations. However, in contrast to vertical load, lateral load effects on buildings are not linear and increase rapidly with increase in height. For example under wind load , the overturning moment at the base of buildings varies approximately as the square of a buildings may vary as the fourth power of buildings height , other things being equal. Earthquake produces an even more pronounced effect.When the structure for a low-or medium-rise building is designed for dead and live load, it is almost an inherent property that the columns, walls, and stair or elevator shafts can carry most of the horizontal forces. The problem is primarily one of shear resistance. Moderate addition bracing for rigid frames in “short” buildings can easily be provided by filling certain panels (or even all panels) without increasing the sizes of thecolumns and girders otherwise required for vertical loads.Unfortunately, this is not is for high-rise buildings because the problem is primarily resistance to moment and deflection rather than shear alone. Special structural arrangements will often have to be made and additional structural material is always required for the columns, girders, walls, and slabs in order to made a high-rise buildings sufficiently resistant to much higher lateral deformations.As previously mentioned, the quantity of structural material required per square foot of floor of a high-rise buildings is in excess of that required for low-rise buildings. The vertical components carrying the gravity load, such as walls, columns, and shafts, will need to be strengthened over the full height of the buildings. But quantity of material required for resisting lateral forces is even more significant.With reinforced concrete, the quantity of material also increases as the number of stories increases. But here it should be noted that the increase in the weight of material added for gravity load is much more sizable than steel, whereas for wind load the increase for lateral force resistance is not that much more since the weight of a concrete buildings helps to resist overturn. On the other hand, the problem of design for earthquake forces. Additional mass in the upper floors will give rise to a greater overall lateral force under the of seismic effects.In the case of either concrete or steel design, there are certain basic principles for providing additional resistance to lateral to lateral forces and deflections in high-rise buildings without too much sacrifire in economy.(1) Increase the effective width of the moment-resisting subsystems. This is very useful because increasing the width will cut down the overturn force directly and will reduce deflection by the third power of the width increase, other things remaining cinstant. However, this does require that vertical components of the widened subsystem be suitably connected to actually gain this benefit.(2) Design subsystems such that the components are made to interact in the most efficient manner. For example, use truss systems with chords and diagonals efficiently stressed, place reinforcing for walls at critical locations, and optimize stiffness ratios for rigid frames.(3) Increase the material in the most effective resisting components. For example, materials added in the lower floors to the flanges of columns and connecting girders will directly decrease the overall deflection and increase the moment resistance without contributing mass in the upper floors where the earthquake problem is aggravated.(4) Arrange to have the greater part of vertical loads be carried directly on the primary moment-resisting components. This will help stabilize the buildings against tensile overturning forces by precompressing the major overturn-resisting components.(5) The local shear in each story can be best resisted by strategic placement if solid walls or the use of diagonal members in a vertical subsystem. Resisting these shears solely by vertical members in bending is usually less economical, since achieving sufficient bending resistance in the columns and connecting girders will require more material and construction energy than using walls or diagonal members.(6) Sufficient horizontal diaphragm action should be provided floor. This will help to bring the various resisting elements to work together instead of separately.(7) Create mega-frames by joining large vertical and horizontal components such as two or more elevator shafts at multistory intervals with a heavy floor subsystems, or by use of very deep girder trusses.Remember that all high-rise buildings are essentially vertical cantilevers which are supported at the ground. When the above principles are judiciously applied, structurally desirable schemes can be obtained by walls, cores, rigid frames, tubular construction, and other vertical subsystems to achieve horizontal strength and rigidity.2. Shear-Wall SystemsShear wall structure is reinforced concrete wallboard to replace with beam-column frame structure of, can undertake all kinds of loads, and can cause the internal force of the structure effectively control the horizontal forces with reinforced concrete wallboard, the vertical and horizontal force to bear the structure called the shear wall structure. This structure was in high-rise building aplenty, so, homebuyers can need not be blinded by its terms. Shear wall structure refers to the vertical of reinforced concrete wallboard, horizontal direction is still reinforced concrete slab of carrying the wall, so big a system, that constitutes the shear wall structure. Why call shear wall structure,actually, the higher the wind load building to its push is bigger, so the wind direction of pushing that level, such as promoting the house, below was a binding, the above the wind blows should produce certain swing floating, swing floating restrictions on the very small, vertical wallboard to resist, the wind over, wants it has a force on top, make floor do not produce swing or shift float degrees small, in particular the bounds of structure, such as: the wind from one side, then there is a considerable force board with it braved along the vertical wallboard, the height of the force, is equivalent to a pair of equivalent shearing, like a with scissors cut floor of force building and the farther down, accordingly, the shear strength of such wallboard that shear wall panels, also explains the wallboard vertical bearing of vertical force also not only should bear the horizontal wind loading, including the horizontal seismic forces to one of its push wind.When shear walls are compatible with other functional requirements, they can be economically utilized to resist lateral forces in high-rise buildings. For example, apartment buildings naturally require many separation walls. When some of these are designed to be solid, they can act as shear walls to resist lateral forces and to carry the vertical load as well. For buildings up to some 20storise, the use of shear walls is common. If given sufficient length, such walls can economically resist lateral forces up to 30 to 40 stories or more.However, shear walls can resist lateral load only the plane of the walls ( i.e.not in a diretion perpendicular to them) . Therefore, it is always necessary to provide shear walls in two perpendicular directions can be at least in sufficient orientation so that lateral force in any direction can be resisted. In addition, that wall layout should reflect consideration of any torsional effect.In design progress, two or more shear walls can be connected to from L-shaped or channel-shaped subsystems. Indeed, internal shear walls can be connected to from a rectangular shaft that will resist lateral forces very efficiently. If all external shear walls are continuously connected , then the whole buildings acts as tube , and connected , then the whole buildings acts as a tube , and is excellent Shear-Wall Systems resisting lateral loads and torsion.Whereas concrete shear walls are generally of solid type with openings whennecessary, steel shear walls are usually made of trusses. These trusses can have single diagonals, “X” diagonals, or “K” arrangements. A trussed wall will have its members act essentially in direct tension or compression under the action of view, and they offer some opportunity and deflection-limitation point of view, and they offer some opportunity for penetration between members. Of course, the inclined members of trusses must be suitable placed so as not to interfere with requirements for windows and for circulation service penetrations though these walls.As stated above, the walls of elevator, staircase, and utility shafts form natural tubes and are commonly employed to resist both vertical and lateral forces. Since these shafts are normally rectangular or circular in cross-section, they can offer an efficient means for resisting moments and shear in all directions due to tube structural action. But a problem in the design of these shafts is provided sufficient strength around door openings and other penetrations through these elements. For reinforced concrete construction, special steel reinforcements are placed around such opening .In steel construction, heavier and more rigid connections are required to resist racking at the openings.In many high-rise buildings, a combination of walls and shafts can offer excellent resistance to lateral forces when they are suitably located ant connected to one another. It is also desirable that the stiffness offered these subsystems be more-or-less symmertrical in all directions.3. Rigid-Frame SystemsFrame structure is to point to by beam and column to just answer or hinged connection the structure of bearing system into constitute beam and column, namely the framework for common resistance appeared in the process of horizontal load and vertical load. Using structure housing wall not bearing, only play palisade and space effect, generally with the aerated concrete prefabricated, expansion perlite, hollow bricks or porous brick, pumice, vermiculite, taoli etc lightweight plank to wait materials bearing or assembly and into.Frame structure shortcoming for: frame node stress concentration significantly; Frame structure of the lateral stiffness small, flexible structure frame, in strongearthquake effect, horizontal displacement structures result is larger, easy cause serious non-structural broken sex; The steel and cement contents of the total number of larger, more component, hoisting number, joint workload big, procedures, waste human, construction by the seasons, environmental impact is bigger; Not suitable for build high-rise building, the frame is composed of by beam-column system structure, its pole bearing capacity and rigidity are low, especially the horizontal (even consider cast-in-situ floor with beam to work together to improve the floor level, but is also limited stiffness), it the mechanical characteristics similar to vertical cantilever beam, the overall level of shear displacement on the big with small, but relatively under floors are concerned, interlayer deformation under the small, how to improve the framework design resist lateral stiffness and control good structure for important factors, lateral move for reinforced concrete frame, when the height of the great, layer quite long, structure of each layer of not only column bottom of axial force are big, and beam and column generated by the horizontal load the bending moment and integral side move also increased significantly, leading to the section size and reinforcement of architectural layout increases, and the treatment of space, may cause difficulties, the influence of rational use of architectural space in materials consumption and cost, unreasonable, also tend to be generally applied in construction, so no more than 15 layer houses.In the design of architectural buildings, rigid-frame systems for resisting vertical and lateral loads have long been accepted as an important and standard means for designing building. They are employed for low-and medium means for designing buildings. They are employed for low- and medium up to high-rise building perhaps 70 or 100 stories high. When compared to shear-wall systems, these rigid frames both within and at the outside of a buildings. They also make use of the stiffness in beams and columns that are required for the buildings in any case , but the columns are made stronger when rigidly connected to resist the lateral as well as vertical forces though frame bending.Frequently, rigid frames will not be as stiff as shear-wall construction, and therefore may produce excessive deflections for the more slender high-rise buildingsdesigns. But because of this flexibility, they are often considered as being more ductile and thus less susceptible to catastrophic earthquake failure when compared with shear-wall designs. For example , if over stressing occurs at certain portions of a steel rigid frame ( i.e.,near the joint ) , ductility will allow the structure as a whole to deflect a little more , but it will by no means collapse even under a much larger force than expected on the structure. For this reason, rigid-frame construction is considered by some to be a “best”seismic-resisting type for high-rise steel buildings. On the other hand, it is also unlikely that a well-designed share-wall system would collapse.In the case of concrete rigid frames, there is a divergence of opinion. It true that if a concrete rigid frame is designed in the conventional manner, without special care to produce higher ductility, it will not be able to withstand a catastrophic earthquake that can produce forces several times longer than the code design earthquake forces. Therefore, some believe that it may not have additional capacity possessed by steel rigid frames . But modern research and experience has indicated that concrete frames can be designed to be ductile, when sufficient stirrups and joinery reinforcement are designed in to the frame. Modern buildings codes have specifications for the so-called ductile concrete frames. However, at present, these codes often require excessive reinforcement at certain points in the frame so as to cause congestion and result in construction difficulties. Even so, concrete frame design can be both effective and economical.Of course, it is also possible to combine rigid-frame construction with shear-wall systems in one buildings, For example, the buildings geometry may be such that rigid frames can be used in one direction while shear walls may be used in the other direction.4. The frame shear wall structureFrame-shear wall structure also called box shear structure, this kind of structure is decorated in the framework of a certain number of shear wall, constitute the use of flexible free space and satisfy different building functional requirement, also have enough shear wall, there is considerable stiffness, box shear structure stress features, is the framework and shear wall structure two different resist lateral force of the structureof the new forces, so its frame forms different from pure frame structure of framework, shear wall structure of the box shear is different from the shear wall structure of shear wall. Because, in the lower floors, shear wall displacement is lesser, it took frame type curve by bending deformation, shear wall inherit most horizontal force, the upper floors, by contrast, shear wall displacement is more and more big, the outside of the trend, and there is a framework of adduction, frame shear wall trend according to shear curve pull deformation, frame of the loading except burden level force produced outside, still extra burden the shear pull back of additional levels of force, shear wall not only the horizontal force produced bear loads, but also because to frame an additional level force and bear minus shear, so, the upper floor even produced the loading framework of shear small, floor also appears considerable shear.5. SummaryAbove states is the high-rise construction ordinariest structural style. In the design process, should the economy practical choose the reasonable form as far as possible.译文:高层建筑结构形式摘要:高层建筑是指超过一定高度和层数的多层建筑。

In general,surfacepreparation of the substrate concrete is considered essential to achieve a durable repair. In thisexperiment, the ``smooth sur face’’ system showed more desirable behavior in the crack pattern and the crack widths than the ``rough surface’’ system. This demonstrates that the smooth surface system is preferable to the rough surface system, from the view point of obtaining durable repair structure. The special phenomenon of kink-crack trapping which prevents the typical failuremodes of delamination or spalling in repaired systems is best revealed when the substrate concrete is prepared to have a smooth surface prior to repair. This is in contrast to the standard approach when the substrate concrete is deliberately roughened to create better bonding to the new concrete. Ó 2000 Elsevier Science Ltd.

IntroductionEngineered cementitious composites (ECCs) [1,2] are high performance fiber-reinforced cement based composite materials designed with micromechanical principles. Micromechanicalparameters associated with fiber, matrix and interface are combined to satisfy a pair of criteria, the first crack stress criterion and steady state cracking criterion [3] to achieve the strain hardening behavior. Micromechanics allows optimization of the composite for high performance while minimizing the amount of reinforcing fibers (generally less than 2-3%). ECC has a tensile strain capacity of up to 6% and exhibits pseudo-strain hardening behavior accompanied by multiple cracking. It also has high ultimate tensile strength (5-10 MPa), modulus of rupture (8-25 MPa), fracture toughness (25-30 kJ/m2) and compressive strength (up to 80 MPa) and strain (0.6%). A typical tensile stress-strain curve is shown in Fig. 1. ECC has its uniqueness not only insuperior mechanical properties in tension or in relatively small amount ofchopped fiber usage but also in micromechanical methodology in material design.The use of ECC for concrete repair was proposed by Li et al. [4], and Lim and Li [5]. In theseexperiments, specimens representative of an actual repair system - bonded overlay of a concrete pavement above a joint, were used. It was shown that the common failure phenomenona ofspalling or delamination in repaired concrete systems were eliminated. Instead, microcracksemanated from the tips of defects on the ECC/concrete interface, kinked into and subsequently were arrested in the ECC material (see Fig. 2, [5]). The tendency for the interface crack to kink into the ECC material depends on the competing driving force for crack extension at differentorientations, and on the competing crack extension resistance along the interface and into the ECC material. A low initial toughness of ECC combined with a high Mode II loading configuration tends to favor kinking. However, if the toughness of ECC remains low after crack kinking, this crack will propagate unstably to the surface, forming a surface spall. This is the typically observed phenomenon associated with brittle concrete and even fiber-reinforced concrete (FRC). In the case of ECC, the kinked crack is trapped or arrested in the ECC material, dueto the rapidly rising toughness of the ECC material. Conceptually, the ECC behaves like a material with strong R-curve behavior, with lowinitial toughness similar to that of cement (0.01 kJ/m2) and high plateau toughness (25-30 kJ/m2). After kinked crack arrest,additional load can drive further crackextension into the interface, followed by subsequent kinking and arrest.Details of the energetics of kink-crack trapping mechanism can befound in [5]. It was pointed out that this kink-crack trapping mechanism could serve as a means for enhancing repaired concrete system durability.In standard concrete repair, surface preparation of the substrate concrete is considered critical in achieving a durable repair [6]. Inthe study of Lim and Li [5], the ECC is cast onto a diamond saw cut surface of the concrete. Hence, the concrete surface is smooth and is expected as a result to produce a low toughness interface. Higherinterface roughness has been associated with higher interface toughnessin bi-material systems [7].In this paper, this particular aspect of the influence of surface preparation on the kink-crack trapping phenomenon is investigated. Specifically, the base concrete surfaces were prepared by threedifferent methods. The first surface was obtained as cut surface byusing a diamond saw (smooth surface), similar to that used in theprevious study [5]. The second one was obtained by applying a lubricanton the smooth surface of the concrete to decrease the bond between thebase concrete and the repair material. This surface was applied only in one test case to examine the effect of weak bond of interface on the fracture behavior of the repaired specimen. The third surface was prepared with a portable scarifier to produce a roughened surface (rough surface) from a diamond saw-cut surface.Regarding the repair materials, the water/cement ratio of ECC was varied to control its toughness and strength. Thus, two different mixtures of ECC were used for the comparison of fracture behavior in both smooth and rough surface case. Concrete and steel fiber-reinforced concrete (SFRC) were also used as control repair materials instead of ECC.2. Experimental procedure2.1. Specimens and test methodsThe specimens in this experiment were designed to induce a defect in the form of aninterfacial crack between the repair material and the base concrete, as well as a joint in thesubstrate. Fig. 3 shows the dimensions of the designed specimen and the loading configuration, and these were the same as those of the previous experiment [5]. This loading condition can provide a stable interface crack propagation condition, when the crack propagates along the interface [8].In this experiment, concrete, SFRC and ECC (with two different W/C ratios) were used as therepair materials. Table 1 illustrates the combinations of the repair material and the surface condition of test specimens. The numbers of specimens are also shown in Table 1. Only in the concrete overlay specimens, a special case where lubricant was smeared on the concrete smooth surface was used.The mix proportions of materials are shown in Table 2. Ordinary mixture proportions wereadopted in concrete and SFRC as controls for comparisons with ECC overlay specimens. The steel fiber for SFRC was ``I.S fiber’’, straight with indented surfaceand rectangular cross-section (0.5* 0.5 mm2), 30 mm in length. An investigation using a steel fiber with hooked ends had already been performed in the previous study [5]. Polyethylene fiber (Trade name Spectra 900) with 19 mm length and 0.038 mm diameter was used for ECC. The elastic modulus, the tensile strength and the fiber density of Spectra 900 were 120 GPa, 2700 MPa and 0.98 g/cm3, respectively. Two different ECCs were used with different water/cement ratios. The mechanical properties of the base concrete and the repair materials are shown in Table 3. The tensile strain capacity of the ECC materials are not measured, but are estimated to be in excess of 3% based on test results of similar materials [2].An MTS machine was used for loading. Load and load point displacement were recorded. The loading rate in this experiment was0.005 mm/s. After the final failure of specimens, interface crack (extension) lengths were measured at both (left and right) sides of a specimen as the distance from a initial notch tip to a propagated crack tip along the interface between the base concrete and the repair material.2.2. Specimen preparationMost of the specimen preparation procedures followed those of the previous work [5]. The base concrete was prepared by cutting a concrete block (see Fig. 4(a)) into four pieces (see Fig. 4(b)) using a diamond saw. Two out of the four pieces were usedfor one smooth surface repairspecimen. In order to make a rough surface, a cut surface was roughened uniformly with ascarifier for 30 s. To prepare a repair specimen in the form of an overlay system, a repair material was cast against either the smooth surface or the rough surface of the base concrete blocks (see Fig. 5). Special attention was paid both to maintain cleanliness and to provide adequate moisture on the base concrete surface just before the casting. In two of the concrete overlay specimens, lubricant was sprayed on the smooth surface just before concrete casting. The initial notch and joint were made by applying a smooth tape on the base concrete before casting the repair materials(see Fig. 4(c)).The specimens were cured for 4 weeks in water. Eventually, the base concrete was cured for a total of 8 weeks, and repair materials were cured for 4 weeks in water. The specimens were dried for 24 h before testing.3. Results and discussion3.1. Comparison of the ECC overlay system with the control systemsFig. 6 shows the representative load-deflection curves in each test case. The overall peak load and deflection at peak load are recorded in Table 4. In the ECC overlay system, the deflections at peak load, which reflect the system ductility, are considerably larger than those of both theconcrete overlay (about one order of magnitude higher) and the SFRC overlay system (over five times). These results show good agreement with the previous results [5]. Moreover, it is clear fromFig. 6 that the energy absorption capacity in the ECC overlay system is much enhanced when it is compared with the other systems. This significant improvement in ductility and in energyabsorption capacity of the ECC overlay system is expected to enhance the durability of repaired structures by resisting brittle failure. The ECC overlay system failed without spalling ordelamination of the interface, whereas, both the concrete and SFRC overlay systems failed by spalling in these experiments (Fig. 7).3.2. Influence of surface preparationBoth in the concrete overlay system and the SFRC overlay system, the peak load and thedeflection at peak load do not show significant differences between smooth surface specimen and rough surface specimen (Table 4). Thetypical failure mode for both overlay systems (for smooth surface) is shown in Fig. 7. In the concrete overlay specimen with lubricant on the interface, delamination between repair concrete and substrate occurred first, followed by a kinked crack which propagates unstably to the surface of the repair concrete. On the other hand, in the concrete overlay system without lubricant, the initial interface crack kinked out from the interface into the repair concrete with a sudden load drop, without any interface delamination. The fractured halves of the specimens separated completely in both smooth surface specimens and rough surfacespecimens. In the SFRC overlay system, the initial interface crack also kinked out into the SFRC and the load decreased gradually in both surface conditions of specimen. In all these repairsystems, a single kink-crack always leads to final failure, and the influence of surface preparation is not reflected in the experimental data. Instead, only the fracture behavior of the repair material (concrete versus SFRC) are revealed in the test data. These specimen failures are characterized bya single kinked crack with immediate softening following elastic response.。

外文:The outside structure of the pavilion and its reflection in the proposed arrangement of its inside functions impose on the visitors taking and following a route which is consistent withthe logic of the building. The entranceway ——an interlude betweenan inside and outside body of the construction, is accesible from the square marked out between the pavilions . The partial roof created by the fold in the building ,allows for arranging an open-air restaurant as well as for providing the queues of visitors a shelter from the elements . The entrance opens onto the hall containing the information centre , a restaurant , and a shop . Next the visitos proceed to the main ,full-height exhibition area of the pavilion . It is the space painted with the light filtering through the cut-out patterns of the elevation creating a〝chiarocuro〞effect, but also the place where thr inner ,solid wallsof the pavilion can function as screenson which the screens of polish city life are projected . consequently ,the inner of the building will creat a background for scheduled performances and presentations,e.g.directly connected with depicting the life of a typical Polish marked place . The concert hall which is located above the entranceway roof can be accessed from this area . auxiliaryfunctions have been designed in the lowest part of the building, under the ramp leading onto the rooftop.Continuing the route the visitors enter the area of the exhibition proper ,devoted to the future of the citise . The wooden, ground-level floor is gradually rising , acquiring the form of terraced stairs and becoming an auditorium for performance taking place below. The stairs take the visiters onto the exhibition ramp, suspended in the pavilion space and leading to the mezzanine where the exhibition of Polish design and an additional bar are to be located. The last strech of the ramp leads onto the roof level——the viewing spot . From here ,the visitors can begin their descent on the rooftop, following the line of greenery elements or small architectural forms until they reach their starting point ——the entrance to the pavilion. The opposite direction of sightseeing may be considered as well. The sloping rooftop creats the possibility of arranging an open-air film shows ,theatical performances or concerts.出自《世界建筑》11/2009 机遇之地:波兰P80-P83 出版社:世界建筑杂志社波士顿会议和展览中心Boston Convention and Exhibition Center建筑设计师:拉斐尔•维诺里位于南波士顿中心的临水地区,新的BECE代表了城市进入会议设施市场的顶端。

This paper discusses how to carry on planning and design of commercial buildings, the construction of a rational, reasonable, appropriate business building, so as to create a good social and economic benefits. Keywords: construction planning; commercial buildings; architectural designPrefaceComprehensive is the development trend of modern commercial buildings, architects in the design of commercial buildings and functions are changing, different positioning of planning, business characteristics and local cultural influence commercial building mode, which requires us to continuously improve our project products, create more in line with the business needs of the best plan and design works, and finally let investors and consumers feel a constant value, so that they feel superior combination of spatial continuous operation, let the customer feel shopping pleasure, feel the beauty of life and the world.mercial architectural schemeCommercial buildings are generally large investment, high risk, long cycle, the successful operation of returns, different commercial patterns determine different commercial building form, and commercial pattern is determined and market positioning, the positioning accuracy of the architect, to commercial building various functions, property, facilities should have full understanding and effective organization, and different commercial construction planning ideas to produce commercial architectural design works are different, economic benefits of investment has great difference. Good architectural planning has decided the success or failure of architectural design.1.Market survey of commercial building design must be based on the market survey results. Based on the characteristics and trend of foreign consumption, economic conditions, traffic conditions, the surrounding commercial pattern, city infrastructure, city development planning, full market research business situation, on the project itself, choose format, format portfolio, the distribution of industrial chain and area proportion, industry selection, distribution and area ratio to the shops, division, architectural form, area and the floor function, people oriented system, project environment and supporting facilities are set in advance. Provide design basis for the architect to design.2.Mode demand regardless of commercial building is rental, sale or rental run combination, the most important is to determine the main format, for commercial buildings,different types of decision model is different, its business scale, function flow, and so on are designed by itself to determine, different formats have different functional requirements, and design the use is required by the business decisions rather than the developer to advocate. The lack of directional design basis, the design appears to be universal, but shoot at random. Once the function with the shop owner conflict, the design must be from the beginning. Language planning can increase the early unnecessary cost and later investment difficulty. Therefore, architects should design according to different formats of different architectural space mode analysis and recommendations.3.In commercial buildings in the process of planning, commercial real estate is the key to grasp the global experts and architects. Commercial real estate planner requires multidisciplinary personnel coordination ability of organization, according to the project of regional history and culture characteristic, according to local consumer preferences, in particular, the design project of the overall concept, culture orientation and market orientation is determined. At present, the commercial real estate projects generally organized by developers to overall planning, the investment in the project needs and business management experts, business format store managers and retail marketing planner, planner, communication landscape planners, architects, etc. In the implementation of construction plan, still need to urban planner, computer talented person to participate, to form a complete construction plans. Neither side may be arranged to replace, the architectural design is inclusive and absorbing these opinions, solutions and professional values of materialized labor and can form a complete architectural planning and design.4.Sustainable development and the characteristics of commercial building is a public place, with the development of business, commercial buildings in 5-6 years will be to do a decoration, simple and durable quality, less as far as possible need to repair and maintenance, and at the same time, according to the different project environment and commercial content is flexible to adapt and ultimately the value of investors and consumers are continuous. Complete function, rich forms, and space is varied, characteristic, design must be the contemporary tendency of time again at the same time, in all sorts of culture and the differences between s resonate.mercial building designCommercial building design is for the purpose of the construction project to produce a good and lasting economic benefits, the architect in commercial building design is to realize project to achieve a dynamic model of investment return, is to complete a final acceptance by consumers and continuous use of building products. Prophase planning orientation, investment, operation and management, each situation is very complex, has brought great influence, architecture design is an important link. And architects for commercial architecture design is inclusive and absorbing these opinions, solutions and professional values of materialized labor and can form a complete works of architectural design.(1)Formats combination designThe composition of commercial complex is decided by the business itself industry value chain, what kind of business combination is better for business. Architects should accordingto the preliminary planning and positioning, the first investment, operation and management of the planning scheme, starting from the basic function and practical application of building, clear the relationship between the function, space, environment, in line with The Times to design not only requires a new breath, also requires a reasonable and clear arrangement of the whole space functional requirements, and actively guide the passenger flow, manufacturing flow, different articles require different forms of space and location, reasonable distribution area, the partition of floor paving segmentation and supporting facilities design can avoid all kinds of goods mixed Chen, mixed traffic situation, the architect should create rich, flexible, comply with the appropriate space to contain different aspects of business combination technology needs. Must do to make it a complex, the industrial chain, industrial chain out after the value chain came out, can produce all kinds of benefits.(2)Pattern designPlanning, design of commercial building in different commercial real estate development mode, have completely different results. Rent is not only sales, emphasizing on management and value-added shops, if considering concurrently, also consider the preferences and requirements of the buyer shops. Commercial buildings due to the different requirements for merchants function layout is different, also different brands to the layout of the same forms are different. By the limit of commercial buildings, or different development cycle, or running effect is different. Those who do not conform to the business law of commercial building design, although space modeling is rich, has implied the bad management of hidden trouble. Therefore, meet the demand of merchants, digest the negative influence of all kinds of changes, architects in the design of the flexible space combination, providing different pattern design, to the use of a variety of forms do fully consider function of balance and coordination. Commercial building itself the function of the combination is very complex, for commercial, residential, office each mixed complex project, the process will be more difficult. Commercial and apartment part often deployed in a low-end, office and hotel in the high-end. The advantages of this design can facilitate the building line layout; Low-end flat layer in the core tube location is advantageous to the toilet set up; High-end part of the landscape advantage is more advantageous to project high value products. But in the concrete project, but should also fully consider building itself the vertical transportation efficiency of the impact on business. In the design of architectural plane layout, space efficiency will approach combined with architectural form and structure. For example, many senior project adopted the practice of Angle, when the design according to the economy, it can increase economic returns of about 30%, but in the specific project be careful not to damage to the corner form.(3)The guidance system designStream of people, logistics, decision function layout reasonable guidance system is the key to the success of commercial building design. Make sure people line, logistics, inward and outward, channel form, to make the layout of the commercial function, consumer groups have a wide range of interest and today free time, thus providing rich architectural space, integrating shopping, entertainment, leisure and so on need comprehensive shopping mall is their needs. Rich function as much as possible to meet the requirements of the customers, but also satisfy the buyers (pavement investors, business investors) needs to provide convenient logistics channel. And express more interest in the construction details. And then to createnew business environment. Let the consumer feel the pleasure shopping consumption, feel the beauty of life and the world at the same time, create more economic benefits for store operators.(4)Green building and characteristicGreen building on the one hand can save energy, on the other hand the sustainable of benefits will far outweigh the prophase investment so as to achieve the value of overall implementation, green buildings gives the possibility of ability of sustainable development and alteration, when architects in the design of commercial buildings so there is no need to do best, do it right, and not have to do much more luxurious style reflected is the commercial buildings, stronger in proper. Commercial buildings tend to be the center of the city commercial culture, different cities have different style, therefore, the architects in the use of his style and technique, need deep understanding urban commercial culture characteristics, extract the essence of the regional culture, architectural design make commercial buildings should have cultural features, local feature, more want to highlight the characteristics of the formats, spatial characteristics, cultural characteristics used in commercial buildings, not only can sense the material shell, are showing strong commercial buildings.3.ConclusionModern commercial architecture planning and design major programs, including the investment purpose and the understanding of the business environment for investors, commercial content on the project, the location of the business environment of consumer behavior, commercial buildings, the understanding of the business concept research, commercial building project planning, design process and method of design, for project construction total plane design and auxiliary space design professional design, space form and form design, the project design space and form of management main body,property requirements,facilities and equipment requirements,architectural engineering and construction of the professional requirement.中文译文:浅谈商业建筑规划设计摘要:商业建筑现已成为除居住建筑以外,最引人注目的,对城市活力和景观影响最大的建筑类型,商业建筑规划设计将面临更广泛的问题。

forced concrete structure reinforced with anoverviewReinSince the reform and opening up, with the national economy's rapid and sustained development of a reinforced concrete structure built, reinforced with the development of technology has been great. Therefore, to promote the use of advanced technology reinforced connecting to improve project quality and speed up the pace of construction, improve labor productivity, reduce costs, and is of great significance.Reinforced steel bars connecting technologies can be divided into two broad categories linking welding machinery and steel. There are six types of welding steel welding methods, and some apply to the prefabricated plant, and some apply to the construction site, some of both apply. There are three types of machinery commonly used reinforcement linking method primarily applicable to the construction site. Ways has its own characteristics and different application, and in the continuous development and improvement. In actual production, should be based on specific conditions of work, working environment and technical requirements, the choice of suitable methods to achieve the best overall efficiency.1、steel mechanical link1.1 radial squeeze linkWill be a steel sleeve in two sets to the highly-reinforced Department with superhigh pressure hydraulic equipment (squeeze tongs) along steel sleeve radial squeeze steel casing, in squeezing out tongs squeeze pressure role of a steel sleeve plasticity deformation closely integrated with reinforced through reinforced steel sleeve and Wang Liang's Position will be two solid steel bars linkedCharacteristic: Connect intensity to be high, performance reliable, can bear high stress draw and pigeonhole the load and tired load repeatedly.Easy and simple to handle, construction fast, save energy and material, comprehensive economy profitable, this method has been already a large amount of application in the project.Applicable scope : Suitable for Ⅱ, Ⅲ, Ⅳgrade reinforcing bar (including welding bad reinfor cing bar ) with ribbing of Ф 18- 50mm, connection between the same diameter or different diameters reinforcing bar .1.2must squeeze linkExtruders used in the covers, reinforced axis along the cold metal sleeve squeeze dedicated to insert sleeve Lane two hot rolling steel drums into a highly integrated mechanical linking methods.Characteristic: Easy to operate and joining fast and not having flame homework , can construct for 24 hours , save a large number of reinforcing bars and energy.

本科毕业设计外文资料翻译1.英文题目:The Edycation Of The ArchItect 2.中文题目:建筑师的培养学院(部):土木建筑学院专业班级:外文资料The Edycation Of The ArchItectThe architect should be equipped with knowledge of many branches of study and varied kinds of learning, for it is by his judgement that all work done by the other arts is put to test. This knowledge is the child of practice and theory. Practice is the continuous and regular exercise of employment where manual work is done with any necessary material according to the design of a drawing. Theory, on the other hand, is the ability to demonstrate and explain the productions of dexterity on the principles of proportion.2. It follows, therefore, that architects who have aimed at acquiring manual skill without scholarship have never been able to reach a position of authority to correspond to their pains, while those who relied only upon theories and scholarship were obviously hunting the shadow, not the substance. But those who have a thorough knowledge of both, like men armed at all points, have the sooner attained their object and carried authority with them.3. In all matters, but particularly in architecture, there are these two points:--the thing signified, and that which gives it its significance. That which is signified is the subject of which we may be speaking; and that which gives significance is a demonstration on scientific principles. It appears, then, that one who professes himself an architect should be well versed in both directions. He ought, therefore, to be both naturally gifted and amenable to instruction. Neither natural ability without instruction nor instruction without natural ability can make the perfect artist. Let him be educated, skilful with the pencil, instructed in geometry, know much history, have followed the philosophers with attention, understand music, have some knowledge of medicine, know the opinions of the jurists, and be acquainted with astronomy and the theory of the heavens.4. The reasons for all this are as follows. An architect ought to be an educated man so as to leave a more lasting remembrance in his treatises. Secondly, he must have a knowledge of drawing so that he can readily make sketches to show the appearance of the work which he proposes. Geometry, also, is of much assistance in architecture, and in particular it teaches us the use of the rule and compasses, by which especially we acquire readiness in making plans for buildings in their grounds, and rightly apply the square, thelevel, and the plummet. By means of optics, again, the light in buildings can be drawn from fixed quarters of the sky. It is true that it is by arithmetic that the total cost of buildings is calculated and measurements are computed, but difficult questions involving symmetry are solved by means of geometrical theories and methods.5. A wide knowledge of history is requisite because, among the ornamental parts of an architect's design for a work, there are many the underlying idea of whose employment he should be able to explain to inquirers. For instance, suppose him to set up the marble statues of women in long robes, called Caryatides, to take the place of columns, with the mutules and coronas placed directly above their heads, he will give the following explanation to his questioners. Caryae, a state in Peloponnesus, sided with the Persian enemies against Greece; later the Greeks, having gloriously won their freedom by victory in the war, made common cause and declared war against the people of Caryae. They took the town, killed the men, abandoned the State to desolation, and carried off their wives into slavery, without permitting them, however, to lay aside the long robes and other marks of their rank as married women, so that they might be obliged not only to march in the triumph but to appear forever after as a type of slavery, burdened with the weight of their shame and so making atonement for their State. Hence, the architects of the time designed for public buildings statues of these women, placed so as to carry a load, in order that the sin and the punishment of the people of Caryae might be known and handed down even to posterity.6. Likewise the Lacedaemonians under the leadership of Pausanias, son of Agesipolis, after conquering the Persianarmies, infinite in number, with a small force at the battle of Plataea, celebrated a glorious triumph with the spoils and booty, and with the money obtained from the sale thereof built the Persian Porch, to be a monument to the renown and valour of the people and a trophy of victory for posterity. And there they set effigies of the prisoners arrayed in barbarian costume and holding up the roof, their pride punished by this deserved affront, that enemies might tremble for fear of the effects of their courage, and that their own people, looking upon this ensample of their valour and encouraged by the glory of it, might be ready to defend their independence. So from that time on, many have put up statues of Persians supporting entablatures and their ornaments, and thus from that motive have greatly enriched the diversity of their works. There are other stories of thesame kind which architects ought to know.7. As for philosophy, it makes an architect high-minded and not self-assuming, but rather renders him courteous, just, and honest without avariciousness. This is very important, for no work can be rightly done without honesty and incorruptibility. Let him not be grasping nor have his mind preoccupied with the idea of receiving perquisites, but let him with dignity keep up his position by cherishing a good reputation. These are among the precepts of philosophy. Furthermore philosophy treats of physics (in Greek phusiologia) where a more careful knowledge is required because the problems which come under this head are numerous and of very different kinds; as, for example, in the case of the conducting of water. For at points of intake and at curves, and at places where it is raised to a level, currents of air naturally form in one way or another; and nobody who has not learned the fundamental principles of physics from philosophy will be able to provide against the damage which they do. So the reader of Ctesibius or Archimedes and the other writers of treatises of the same class will not be able to appreciate them unless he has been trained in these subjects by the philosophers.8. Music, also, the architect ought to understand so that he may have knowledge of the canonical and mathematical theory, and besides be able to tune ballistae, catapultae, and scorpiones to the proper key. For to the right and left in the beams are the holes in the frames through which the strings of twisted sinew are stretched by means of windlasses and bars, and these strings must not be clamped and made fast until they give the same correct note to the ear of the skilled workman. For the arms thrust through those stretched strings must, on being let go, strike their blow together at the same moment; but if they are not in unison, they will prevent the course of projectiles from being straight.9. In theatres, likewise, there are the bronze vessels (in Greek êcheia) which are placed in niches under the seats in accordance with the musical intervals on mathematical principles. These vessels are arranged with a view to musical concords or harmony, and apportioned in the compass of the fourth, the fifth, and the octave, and so on up to the double octave, in such a way that when the voice of an actor falls in unison with any of them its power is increased, and it reaches the ears of the audience with greater clearness and sweetness. Water organs, too, and the other instruments which resemble them cannot be made by one who is without the principles of music.10. The architect should also have a knowledge of the study of medicine on account of the questions of climates (in Greek klimata), air, the healthiness and unhealthiness of sites, and the use of different waters. For without these considerations, the healthiness of a dwelling cannot be assured. And as for principles of law, he should know those which are necessary in the case of buildings having party walls, with regard to water dripping from the eaves, and also the laws about drains, windows, and water supply. And other things of this sort should be known to architects, so that, before they begin upon buildings, they may be careful not to leave disputed points for the householders to settle after the works are finished, and so that in drawing up contracts the interests of both employer and contractor may be wisely safe-guarded. For if a contract is skilfully drawn, each may obtain a release from the other without disadvantage. From astronomy we find the east, west, south, and north, as well as the theory of the heavens, the equinox, solstice, and courses of the stars. If one has no knowledge of these matters, he will not be able to have any comprehension of the theory of sundials.11. Consequently, since this study is so vast in extent, embellished and enriched as it is with many different kinds of learning, I think that men have no right to profess themselves architects hastily, without having climbed from boyhood the steps of these studies and thus, nursed by the knowledge of many arts and sciences, having reached the heights of the holy ground of architecture.12. But perhaps to the inexperienced it will seem a marvel that human nature can comprehend such a great number of studies and keep them in the memory. Still, the observation that all studies have a common bond of union and intercourse with one another, will lead to the belief that this can easily be realized. For a liberal education forms, as it were, a single body made up of these members. Those, therefore, who from tender years receive instruction in the various forms of learning, recognize the same stamp on all the arts, and an intercourse between all studies, and so they more readily comprehend them all. This is what led one of the ancient architects, Pytheos, the celebrated builder of the temple of Minerva at Priene, to say in his Commentaries that an architect ought to be able to accomplish much more in all the arts and sciences than the men who, by their own particular kinds of work and the practice of it, have brought each a single subject to the highest perfection. But this is in point of fact not realized.13. For an architect ought not to be and cannot be such a philologian as was Aristarchus, although not illiterate; nor a musician like Aristoxenus, though not absolutely ignorant of music; nor a painter like Apelles, though not unskilful in drawing; nor a sculptor such as was Myron or Polyclitus, though not unacquainted with the plastic art; nor again a physician like Hippocrates, though not ignorant of medicine; nor in the other sciences need he excel in each, though he should not be unskilful in them. For, in the midst of all this great variety of subjects, an individual cannot attain to perfection in each, because it is scarcely in his power to take in and comprehend the general theories of them.14. Still, it is not architects alone that cannot in all matters each perfection, but even men who individually practise specialties in the arts do not all attain to the highest point of merit. Therefore, if among artists working each in a single field not all, only a few in an entire generation acquire fame, and that with difficulty, how can an architect, who has to be skilful in many accomplish not merely the feat--in itself a great marvel--of being deficient in none of them, but also that of surpassing all those artists who have devoted themselves with unremitting industry to single fields?15. It appears, then, that Pytheos made a mistake by not observing that the arts are each composed of two things, the actual and the theory of it. One of these, the doing of the work, is proper to men trained in the individual subject, while the other, the theory, is common to all scholars: for example, to physicians and musicians the rhythmical beat of the pulse and its metrical movement. But if there is a wound to be healed or a sick man to be saved from danger, the musician will not call, for the business will be appropriate to the physician. So in the case of a musical instrument, not the physician but the musician will be the man to tune it so that the ears may find their due pleasure in its strains.16. Astronomers likewise have a common ground for discussion with musicians in the harmony of the stars and musical concords in tetrads and triads of the fourth and the fifth, and with geometricians in the subject of vision (in Greek logos optikos); and in all other sciences many points, perhaps all, are common so far as the discussion of them is concerned. But the actual undertaking of works which are brought to perfection by the hand and its manipulation is the function of those who have been specially trained to deal with a single art. It appears, therefore, that he has done enough and to spare who in eachsubject possesses a fairly good knowledge of those parts, with their principles, which are indispensable for architecture, so that if he is required to pass judgement and to express approval in the case of those things or arts, he may not be found wanting. As for men upon whom nature has bestowed so much ingenuity, acuteness, and memory that they are able to have a thorough knowledge of geometry, astronomy, music, and the other arts, they go beyond the functions of architects and become pure mathematicians. Hence they can readily take up positions against those arts because many are the artistic weapons with which they are armed. Such men, however, are rarely found, but there have been such at times; for example, Aristarchus of Samos, Philolaus and Archytas of Tarentum, Apollonius of Perga, Eratosthenes of Cyrene, and among Syracusans Archimedes and Scopinas, who through mathematics and natural philosophy discovered, expounded, and left to posterity many things in connexion with mechanics and with sundials.17. Since, therefore, the possession of such talents due to natural capacity is not vouchsafed at random to entire nations, but only to a few great men; since, moreover, the function of the architect requires a training in all the departments of learning; and finally, since reason, on account of the wide extent of the subject, concedes that he may possess not the highest but not even necessarily a moderate knowledge of the subjects of study, I request, Caesar, both of you and of those who may read the said books, that if anything is set forth with too little regard for grammatical rule, it may be pardoned. For it is not as a very great philosopher, nor as an eloquent rhetorician, nor as a grammarian trained in the highest principles of his art, that I have striven to write this work, but as an architect who has had only a dip into those studies. Still, as regards the efficacy of the art and the theories of it, I promise and expect that in these volumes I shall undoubtedly show myself of very considerable importance not only to builders but also to all scholars.中文翻译建筑师的培养1.建筑师要具备多学科的知识和种种技艺。

土木工程概论摘要:土木工程是个庞大的学科,但最主要的是建筑,建筑无论是在中国还是在国外,都有着悠久的历史,长期的发展历程。

整个世界每天都在改变,而建筑也随科学的进步而发展。

力学的发现,材料的更新,不断有更多的科学技术引入建筑中。

以前只求一间有瓦盖顶的房屋,现在追求舒适,不同的思想,不同的科学,推动了土木工程的发展,使其更加完美。

关键词:土木工程;建筑;力学;材料土木工程是建造各种工程的统称。

它的原意是与“军事工程”相对应的。

在英语中,历史上土木工程、机械工程、电气工程、化工工程都属于Civil Engineering,因为它们都具有民用性。

后来,随着工程科学技术的发展,机械、电气、化工都已逐渐形成独立的科学,Civil Engineering就成为土木工程的专门名词。

至今,在英语中,Civil Engineering还包括水利工程、港口工程;而在我国,水利工程和港口工程也成为与土木工程十分密切的相对独立分支。

土木工程既指建设的对象,即建造在地上,地下,水中的工程设施,也指应用的材料设备和进行的勘测,设计施工,保养,维修等专业技术。

土木工程是一种与人们的衣、食、住、行有着密切关系的工程。

其中与“住”的关系是直接的。

因为,要解决“住”的问题必须建造各种类型的建筑物。

而解决“行、食衣”的问题既有直接的一面,也有间接的一面。

要“行”,必须建造铁路、道路、桥梁;要“食”,必须打井取水、兴修水利、进行农田灌溉、城市供水排水等,这是直接关系。

而间接关系则不论做什么,制造汽车、轮船也好,纺纱、织布、制衣也好,乃至生产钢铁、发射卫星、开展科学研究活动都离不开建造各种建筑物、构筑物和修建各种工程设施。

土木工程随着人类社会的进步而发展,至今已经演变成为大型综合性的学科,它已经出许多分支,如:建筑工程,铁路工程,道路工程,桥梁工程,特种工程结构,给水排水工程,港口工程,水利工程,环境工程等学科。

土木工程作为一个重要的基础学科,有其重要的属性:综合性,社会性,实践性,统一性。

外文文献:Risk Analysis of the International Construction ProjectBy: Paul Stanford KupakuwanaCost Engineering Vol. 51/No. 9 September 2009ABSTRACTThis analysis used a case study methodology to analyse the issues surrounding the partial collapse of the roof of a building housing the headquarters of the Standards Association of Zimbabwe (SAZ). In particular, it examined the prior roles played by the team of construction professionals. The analysis revealed that the SAZ’s traditional construction project was generally characterized by high risk. There was a clear indication of the failure of a contractor and architects in preventing and/or mitigating potential construction problems as alleged by the plaintiff. It was reasonable to conclude that between them the defects should have been detected earlier and rectified in good time before the partial roof failure. It appeared justified for the plaintiff to have brought a negligence claim against both the contractor and the architects. The risk analysis facilitated, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. It further served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense. Clients do not want surprise, and are more likely to engage in litigation when things go wrong.KEY WORDS:Arbitration, claims, construction, contracts, litigation, project and risk The structural design of the reinforced concrete elements was done by consulting engineers Knight Piesold (KP). Quantity surveying services were provided by Hawkins, Leshnick & Bath (HLB). The contract was awarded to Central African Building Corporation (CABCO) who was also responsible for the provision of a specialist roof structure using patented “gang nail” rooftrusses. The building construction proceeded to completion and was handed over to the owners on Sept. 12, 1991. The SAZ took effective occupation of the headquarters building without a certificate of occupation. Also, the defects liability period was only three months .The roof structure was in place 10 years before partial failure in December 1999. The building insurance coverage did not cover enough, the City of Harare, a government municipality, issued the certificate of occupation 10 years after occupation, and after partial collapse of the roof .At first the SAZ decided to go to arbitration, but this failed to yield an immediate solution. The SAZ then decided to proceed to litigate in court and to bring a negligence claim against CABCO. The preparation for arbitration was reused for litigation. The SAZ’s quantified losses stood at approximately $ 6 million in Zimbabwe dollars (US $1.2m) .After all parties had examined the facts and evidence before them, it became clear that there was a great probability that the courts might rule that both the architects and the contractor were liable. It was at this stage that the defendants’ lawye rs requested that the matter be settled out of court. The plaintiff agreed to this suggestion, with the terms of the settlement kept confidential .The aim of this critical analysis was to analyse the issues surrounding the partial collapse of the roof of the building housing the HQ of Standard Association of Zimbabwe. It examined the prior roles played by the project management function and construction professionals in preventing/mitigating potential construction problems. It further assessed the extent to which the employer/client and parties to a construction contract are able to recover damages under that contract. The main objective of this critical analysis was to identify an effective risk management strategy for future construction projects. The importance of this study is its multidimensional examination approach.Experience suggests that participants in a project are well able to identify risks based on their own experience. The adoption of a risk management approach, based solely in past experience and dependant on judgement, may work reasonably well in a stable low risk environment. It is unlikely to be effective where there is a change. This is because change requires the extrapolation of past experience, which could be misleading. All construction projects are prototypes to some extent and imply change. Change in the construction industry itself suggests that past experience is unlikely to be sufficient on its own. A structured approach is required. Such a structure can not and must not replace the experience and expertise of the participant. Rather, it brings additional benefits that assist to clarify objectives, identify the nature of the uncertainties, introduces effective communication systems, improves decision-making, introduces effective risk control measures, protects the project objectives and provides knowledge of the risk history .Construction professionals need to know how to balance the contingencies of risk with their specific contractual, financial, operational and organizational requirements. Many construction professionals look at risks in dividually with a myopic lens and do not realize the potential impact that other associated risks may have on their business operations. Using a holistic risk management approach will enable a fi rm to identify all of the organization’s business risks. This will increase the probability of risk mitigation, with the ultimate goal of total risk elimination .Recommended key construction and risk management strategies for future construction projects have been considered and their explanation follows. J.W. Hinchey stated that there is and can be no ‘best practice’ standard for risk allocation on a high-profile project or for that matter, any project. He said, instead, successful risk management is a mind-set and a process. According to Hinchey, the ideal mind-set is for the parties and their representatives to, first, be intentional about identifying project risks and then to proceed to develop a systematic and comprehensiveprocess for avoiding, mitigating, managing and finally allocating, by contract, those risks in optimum ways for the particular project. This process is said to necessarily begin as a science and ends as an art .According to D. Atkinson, whether contractor, consultant or promoter, the right team needs to be assembled with the relevant multi-disciplinary experience of that particular type of project and its location. This is said to be necessary not only to allow alternative responses to be explored. But also to ensure that the right questions are asked and the major risks identified. Heads of sources of risk are said to be a convenient way of providing a structure for identifying risks to completion of a participant’s part of the project. Effective risk management is said to require a multi-disciplinary approach. Inevitably risk management requires examination of engineering, legal and insurance related solutions .It is stated that the use of analytical techniques based on a statistical approach could be of enormous use in decision making . Many of these techniques are said to be relevant to estimation of the consequences of risk events, and not how allocation of risk is to be achieved. In addition, at the present stage of the development of risk management, Atkinson states that it must be recognized that major decisions will be made that can not be based solely on mathematical analysis. The complexity of construction projects means that the project definition in terms of both physical form and organizational structure will be based on consideration of only a relatively small number of risks . This is said to then allow a general structured approach that can be applied to any construction project to increase the awareness of participants .The new, simplified Construction Design and Management Regulations(CDM Regulations) which came in to force in the UK in April 2007, revised and brought together the existing CDM 1994 and the Construction Health Safety and Welfare(CHSW) Regulations 1996, into a single regulatory package.The new CDM regulations offer an opportunity for a step change in health and safety performance and are used to reemphasize the health, safety and broader business benefits of a well-managed and co-ordinated approach to the management of health and safety in construction.I believe that the development of these skills is imperative to provide the client with the most effective services available, delivering the best value project possible.Construction Management at Risk (CM at Risk), similar to established private sector methods of construction contracting, is gaining popularity in the public sector. It is a process that allows a client to select a construction manager (CM) based on qualifications; make the CM a member of a collaborative project team; centralize responsibility for construction under a single contract; obtain a bonded guaranteed maximum price; produce a more manageable, predictable project; save time and money; and reduce risk for the client, the architect and the CM.CM at Risk, a more professional approach to construction, is taking its place along with design-build, bridging and the more traditional process of design-bid-build as an established method of project delivery.The AE can review the CM’s approach to the work, making helpful recommendations. The CM is allowed to take bids or proposals from subcontractors during completion of contract documents, prior to the guaranteed maximum price (GMP), which reduces the CM’s risk and provides useful input to design. The procedure is more methodical, manageable, predictable and less risky for all.The procurement of construction is also more business-like. Each trade contractor has a fair shot at being the low bidder without fear of bid shopping. Each must deliver the best to get the projec. Competition in the community is more equitable: all subcontractors have a fair shot at the work .A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes. As long as the subcontractors are within the GMP they are reimbursed to the CM, so the CM represents the client in negotiating inevitable changes with subcontractors.There can be similar problems where each party in a project is separately insured. For this reason a move towards project insurance is recommended. The traditional approach reinforces adversarial attitudes, and even provides incentives for people to overlook or conceal risks in an attempt to avoid or transfer responsibility.A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes.

It did appear justified for the plaintiff to have brought a negligence claim against both the contractor and the architects.In many projects clients do not understand the importance of their role in facilitating cooperation and coordination; the design is prepared without discussion between designers, manufacturers, suppliers and contractors. This means that the designer can not take advantage of suppliers’ or contractors’ knowledge of build ability or maintenance requirements and the impact these have on sustainability, the total cost of ownership or health and safety .This risk analysis was able to facilitate, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects.
