毕业论文外文翻译-高层建筑结构High-Rise Building StructureAbstract:High-rise buildings have become common in modern cities across the world. Structural considerations play a crucial role in the planning and design of these buildings. The structural system of a high-rise building must be able to support its own weight as well as any additional loads imposed by occupancy and natural forces such as wind and earthquakes. This paper provides an overview of the structural systems commonly used in high-rise buildings, including reinforced concrete, steel, and hybrid systems. It also discusses the advantages and disadvantages of each system and the factors that affect their selection based on the specific requirements of a building.Introduction:In modern cities, high-rise buildings have become an increasingly popular option for meeting the growing need for office and residential space. High-rise buildings have several advantages, including the efficient use of land, the ability to accommodate large numbers of people, and the provision of spectacular views. To achieve these benefits, it is important to develop a safe and efficient structural system for high-rise buildings.Structural Considerations for High-Rise Buildings:Structural considerations are critical for high-rise buildings. Such structures must be able to support their own weight, as well as resist loads imposed by occupancy and natural forces such as wind and earthquakes. The structural system must also be able to maintain stability throughout the building's lifespan, while providing adequate safety for its occupants.Common Structural Systems for High-Rise Buildings:Reinforced Concrete System:One of the most commonly used structural systems for high-rise buildings is reinforced concrete. This system is desirable because of its strength, durability, and fire resistance. Concrete is also easily moldable, which allows for various shapes and sizes to be used in the building design.Steel System:The steel structural system is another popular choice for high-rise buildings. Steel structures have a high strength-to-weight ratio, which makes them a good choice for taller and lighter buildings. They are also easily adaptable and have high ductility, making them more resistant to earthquake damage.Hybrid System:Hybrid structural systems, which combine the advantages of reinforced concrete and steel, have become increasingly popular in recent years. These systems include concrete encased steel frames, concrete-filled steel tubes, and steel reinforced concrete.Factors Affecting Selection:The selection of a structural system for a high-rise building depends on several factors, including the building height, location, climate, design requirements, and budget. For example, in areas with high wind loads, a steel or hybrid system may be preferable due to its high strength and ductility. In areas with high seismic activity, a reinforced concrete system may be more appropriate because of its superior resistance to earthquake damage.Advantages and Disadvantages of Structural Systems:Each structural system has its advantages and disadvantages. The reinforced concrete system is strong, durable, and fire resistant, but is also heavy and requires a longer construction period. The steel system is adaptable and has a high strength-to-weight ratio, but is also susceptible to corrosion and may require regular maintenance. The hybrid system combines the benefits of both systems but may be more expensive than either system alone.Conclusion:Structural considerations are critical for the planning and design of high-rise buildings. Reinforced concrete, steel, and hybrid systems are the most commonly used structural systems for high-rise buildings. The selection of a system depends on several factors, including the building height, location, climate, design requirements, and budget. Each system has its advantages and disadvantages, and careful consideration of these factors is necessary to develop a safe and efficient structural system for high-rise buildings.。

建筑设计中英文对照外文翻译文献On the other hand, there is a significant amount ofliterature in the field of architecture design that is writtenin foreign languages. While it may not be as readily accessible for non-native speakers, there are many benefits to exploring literature in other languages. For example, architects who are fluent in multiple languages can have a broader understanding of different cultural approaches to architecture. By reading literature in foreign languages, architects can gain insights into design concepts and practices that may not be covered in English-language sources. This can lead to a more diverse and innovative approach to design.However, one challenge with accessing literature in foreign languages is the accuracy of translations. Architecture is a technical field with specific terminology, and it is important to ensure that translations accurately convey the intended meaning. In some cases, the translation of technical terms and concepts may not accurately convey their full meaning, which can lead to misunderstandings or confusion. Architects who rely on translated literature should be cautious and ensure they verify the accuracy of the translations with experts in the field.Despite these challenges, it is essential for architects to explore literature in multiple languages to stay informed and to gain a global perspective on architecture design. By consideringboth English and foreign language translated literature, architects can access a wider range of resources and insights. Additionally, architects should consider collaborating with colleagues who are fluent in different languages to ensure accurate translation and interpretation of foreign language sources.In conclusion, architecture design is a field that benefits from accessing literature in multiple languages. English provides a wealth of resources and is the global language of academia. However, architects who can access and read literature in foreign languages can gain new perspectives and insights into different cultural approaches to design. While caution should be taken to verify the accuracy of translations, architects should explore literature in multiple languages to broaden their understanding and enhance their creative problem-solving skills.。

Hence, he or she well wants to think of evolving a building environment as a total system of interacting and space forming subsystems. Is represents a complex challenge, and to meet it the architect will need a hierarchic design process that provides at least three levels of feedback thinking: schematic,preliminary, and final.Such a hierarchy is necessary if he or she is to avoid being confused , at conceptual stages of design thinking ,by the myriad detail issues that can distract attention from more basic considerations .In fact , we can say that an architect’s ability to distinguish the more basic form the more detailed issues is essential to his success as a designer .The object of the schematic feed back level is to generate and evaluate overall site-plan, activity-interaction, and building-configuration options .To do so the architect must be able to focus on the interaction of the basic attributes of the site context, the spatial organization, and the symbolism as determinants of physical form. This means that ,in schematic terms ,the architect may first conceive and model a building design as an organizational abstraction of essential performance-space in teractions.Then he or she may explore the overall space-form implications of the abstraction. As an actual building configuration option begins to emerge, it will be modified to include consideration for basic site conditions.At the schematic stage, it would also be helpful if the designer could visualize his or her options for achieving overall structural integrity and consider the constructive feasibility and economic ofhis or her scheme .But this will require that the architect and/or a consultant be able to conceptualize total-system structural options in terms of elemental detail .Such overall thinking can be easily fed back to improve the space-form scheme.At the preliminary level, the architect’s emphasis will shift to the elaboration of his or her more promising schematic design options .Here the architect’s structural needs will shift to approximate design of specific subsystem options. At this stage the total structural scheme is developed to a middle level of specificity by focusing on identification and design of major subsystems to the extent that their key geometric, component, and interactive properties are established .Basic subsystem interaction and design conflicts can thus be identified and resolved in the context of total-system objectives. Consultants can play a significant part in this effort; these preliminary-level decisions may also result in feedback that calls for refinement or even major change in schematic concepts.When the designer and the client are satisfied with the feasibility of a design proposal at the preliminary level, it means that the basic problems of overall design are solved and details are not likely to produce major change .The focus shifts again ,and the design process moves into the final level .At this stage the emphasiswill be on the detailed development of all subsystem specifics . Here the role of specialists from various fields, including structural engineering, is much larger, since all detail of the preliminary design must be worked out. Decisions made at this level may produce feedback into Level II that will result in changes. However, if Levels I and II are handled with insight, the relationship between the overall decisions, made at the schematic and preliminary levels, and the specifics of the final level should be such that gross redesign is not in question, Rather, the entire process should be one of moving in an evolutionary fashion from creation and refinement (or modification) of the more general properties of a total-system design concept, to the fleshing out of requisite elements and details.To summarize: At Level I, the architect must first establish, in conceptual terms, the overall space-form feasibility of basic schematic options. At this stage, collaboration with specialists can be helpful, but only if in the form of overall thinking. At Level II, the architect must be able to identify the major subsystem requirements implied by the scheme and substantial their interactive feasibility by approximating key component properties .That is, the properties of major subsystems need be worked out only in sufficient depth to very the inherent compatibility of their basic form-related and behavioral interaction . This will mean a somewhat more specificform of collaboration with specialists then that in level I .At level III ,the architect and the specific form of collaboration with specialists then that providing for all of the elemental design specifics required to produce biddable construction documents .Of course this success comes from the development of the Structural Material.The principal construction materials of earlier times were wood and masonry brick, stone, or tile, and similar materials. The courses or layers were bound together with mortar or bitumen, a tar like substance, or some other binding agent. The Greeks and Romans sometimes used iron rods or claps to strengthen their building. The columns of the Parthenon in Athens, for example, have holes drilled in them for iron bars that have now rusted away. The Romans also used a natural cement called puzzling, made from volcanic ash, that became as hard as stone under water.Both steel and cement, the two most important construction materials of modern times, were introduced in the nineteenth century. Steel, basically an alloy of iron and a small amount of carbon had been made up to that time by a laborious process that restricted it to such special uses as sword blades. After the invention of the Bessemer process in 1856, steel was available in large quantities at low prices. The enormous advantage of steel is its tensile forcewhich, as we have seen, tends to pull apart many materials. New alloys have further, which is a tendency for it to weaken as a result of continual changes in stress.Modern cement, called Portland cement, was invented in 1824. It is a mixture of limestone and clay, which is heated and then ground into a power. It is mixed at or near the construction site with sand, aggregate small stones, crushed rock, or gravel, and water to make concrete. Different proportions of the ingredients produce concrete with different strength and weight. Concrete is very versatile; it can be poured, pumped, or even sprayed into all kinds of shapes. And whereas steel has great tensile strength, concrete has great strength under compression. Thus, the two substances complement each other.They also complement each other in another way: they have almost the same rate of contraction and expansion. They therefore can work together in situations where both compression and tension are factors. Steel rods are embedded in concrete to make reinforced concrete in concrete beams or structures where tensions will develop. Concrete and steel also form such a strong bond─ the force that unites them─ that the steel cannot slip within the concrete. Still another advantage is that steel does not rust in concrete. Acid corrodes steel, whereas concrete has an alkaline chemical reaction, the opposite of acid.The adoption of structural steel and reinforced concrete caused major changes in traditional construction practices. It was no longer necessary to use thick walls of stone or brick for multistory buildings, and it became much simpler to build fire-resistant floors. Both these changes served to reduce the cost of construction. It also became possible to erect buildings with greater heights and longer spans.Since the weight of modern structures is carried by the steel or concrete frame, the walls do not support the building. They have become curtain walls, which keep out the weather and let in light. In the earlier steel or concrete frame building, the curtain walls were generally made of masonry; they had the solid look of bearing walls. Today, however, curtain walls are often made of lightweight materials such as glass, aluminum, or plastic, in various combinations.Another advance in steel construction is the method of fastening together the beams. For many years the standard method was riveting.A rivet is a bolt with a head that looks like a blunt screw without threads. It is heated, placed in holes through the pieces of steel, and a second head is formed at the other end by hammering it to hold it in place. Riveting has now largely been replaced by welding, the joining together of pieces of steel by melting a steel materialbetween them under high heat.Priestess’s concrete is an improved form of reinforcement. Steel rods are bent into the shapes to give them the necessary degree of tensile strengths. They are then used to priestess concrete, usually by one of two different methods. The first is to leave channels in a concrete beam that correspond to the shapes of the steel rods. When the rods are run through the channels, they are then bonded to the concrete by filling the channels with grout, a thin mortar or binding agent. In the other (and more common) method, the priestesses steel rods are placed in the lower part of a form that corresponds to the shape of the finished structure, and the concrete is poured around them. Priestess’s concrete uses less steel and less concrete. Because it is a highly desirable material.Progressed concrete has made it possible to develop buildings with unusual shapes, like some of the modern, sports arenas, with large spaces unbroken by any obstructing supports. The uses for this relatively new structural method are constantly being developed.建筑中的结构设计及建筑材料建筑师必须从一种全局的角度出发去处理建筑设计中应该考虑到的实用活动，物质及象征性的需求。

英文原文Components of A Building and Tall Buildings1. AbstractMaterials and structural forms are combined to make up the various parts of a building, including the load-carrying frame, skin, floors, and partitions. The building also has mechanical and electrical systems, such as elevators, heating and cooling systems, and lighting systems. The superstructure is that part of a building above ground, and the substructure and foundation is that part of a building below ground.The skyscraper owes its existence to two developments of the 19th century: steel skeleton construction and the passenger elevator. Steel as a construction material dates from the introduction of the Bessemer converter in 1885.Gustave Eiffel (1832-1932) introduced steel construction in France. His designs for the Galerie des Machines and the Tower for the Paris Exposition of 1889 expressed the lightness of the steel framework. The Eiffel Tower, 984 feet (300 meters) high, was the tallest structure built by man and was not surpassed until 40 years later by a series of American skyscrapers.Elisha Otis installed the first elevator in a department store in New York in 1857.In 1889, Eiffel installed the first elevators on a grand scale in the Eiffel Tower, whose hydraulic elevators could transport 2,350 passengers to the summit every hour.2. Load-Carrying FrameUntil the late 19th century, the exterior walls of a building were used as bearing walls to support the floors. This construction is essentially a post and lintel type, and it is still used in frame construction for houses. Bearing-wall construction limited the height of building because of the enormous wall thickness required；for instance, the 16-story Monadnock Building built in the 1880’s in Chicago had walls 5 feet (1.5 meters) thick at the lower floors. In 1883, William Le Baron Jenney (1832-1907) supported floors on cast-iron columns to form a cage-like construction. Skeleton construction, consisting of steel beams and columns, was first used in 1889. As a consequence of skeleton construction, the enclosing walls become a “curtain wall” rather than serving a supporting function. Masonry was the curtain wall material until the 1930’s, when light metal and glass curtain walls wer e used. After the introduction of buildings continued to increase rapidly.All tall buildings were built with a skeleton of steel until World War Ⅱ. After thewar, the shortage of steel and the improved quality of concrete led to tall building being built of reinforced concrete. Marina Tower (1962) in Chicago is the tallest concrete building in the United States；its height—588 feet (179 meters)—is exceeded by the 650-foot (198-meter) Post Office Tower in London and by other towers.A change in attitude about skyscraper construction has brought a return to the use of the bearing wall. In New York City, the Columbia Broadcasting System Building, designed by Eero Saarinen in 1962,has a perimeter wall consisting of 5-foot (1.5meter) wide concrete columns spaced 10 feet (3 meters) from column center to center. This perimeter wall, in effect, constitutes a bearing wall. One reason for this trend is that stiffness against the action of wind can be economically obtained by using the walls of the building as a tube；the World Trade Center building is another example of this tube approach. In contrast, rigid frames or vertical trusses are usually provided to give lateral stability.3. SkinThe skin of a building consists of both transparent elements (windows) and opaque elements (walls). Windows are traditionally glass, although plastics are being used, especially in schools where breakage creates a maintenance problem. The wall elements, which are used to cover the structure and are supported by it, are built of a variety of materials: brick, precast concrete, stone, opaque glass, plastics, steel, and aluminum. Wood is used mainly in house construction；it is not generally used for commercial, industrial, or public building because of the fire hazard.4. FloorsThe construction of the floors in a building depends on the basic structural frame that is used. In steel skeleton construction, floors are either slabs of concrete resting on steel beams or a deck consisting of corrugated steel with a concrete topping. In concrete construction, the floors are either slabs of concrete on concrete beams or a series of closely spaced concrete beams (ribs) in two directions topped with a thin concrete slab, giving the appearance of a waffle on its underside. The kind of floor that is used depends on the span between supporting columns or walls and the function of the space. In an apartment building, for instance, where walls and columns are spaced at 12 to 18 feet (3.7 to 5.5 meters), the most popular construction is a solid concrete slab with no beams. The underside of the slab serves as the ceiling for the space below it. Corrugated steel decks are often used in office buildings because the corrugations, when enclosed by another sheet of metal, form ducts for telephone and electrical lines.5. Mechanical and Electrical SystemsA modern building not only contains the space for which it is intended (office, classroom, apartment) but also contains ancillary space for mechanical and electrical systems that help to provide a comfortable environment. These ancillary spaces in a skyscraper office building may constitute 25% of the total building area. The importance of heating, ventilating, electrical, and plumbing systems in an office building is shown by the fact that 40% of the construction budget is allocated to them. Because of the increased use of sealed building with windows that cannot be opened, elaborate mechanical systems are provided for ventilation and air conditioning. Ducts and pipes carry fresh air from central fan rooms and air conditioning machinery. The ceiling, which is suspended below the upper floor construction, conceals the ductwork and contains the lighting units. Electrical wiring for power and for telephone communication may also be located in this ceiling space or may be buried in the floor construction in pipes or conduits.There have been attempts to incorporate the mechanical and electrical systems into the architecture of building by frankly expressing them；for example, the American Republic Insurance Company Building(1965) in Des Moines, Iowa, exposes both the ducts and the floor structure in an organized and elegant pattern and dispenses with the suspended ceiling. This type of approach makes it possible to reduce the cost of the building and permits innovations, such as in the span of the structure.6. Soils and FoundationsAll building are supported on the ground, and therefore the nature of the soil becomes an extremely important consideration in the design of any building. The design of a foundation dependson many soil factors, such as type of soil, soil stratification, thickness of soil lavers and their compaction, and groundwater conditions. Soils rarely have a single composition；they generally are mixtures in layers of varying thickness. For evaluation, soils are graded according to particle size, which increases from silt to clay to sand to gravel to rock. In general, the larger particle soils will support heavier loads than the smaller ones. The hardest rock can support loads up to 100 tons per square foot(976.5 metric tons/sq meter), but the softest silt can support a load of only 0.25 ton per square foot(2.44 metric tons/sq meter). All soils beneath the surface are in a state of compaction；that is, they are under a pressure that is equal to the weight of the soil column above it. Many soils (except for most sands and gavels) exhibit elasticproperties—they deform when compressed under load and rebound when the load is removed. The elasticity of soils is often time-dependent, that is, deformations of the soil occur over a length of time which may vary from minutes to years after a load is imposed. Over a period of time, a building may settle if it imposes a load on the soil greater than the natural compaction weight of the soil. Conversely, a building may heave if it imposes loads on the soil smaller than the natural compaction weight. The soil may also flow under the weight of a building；that is, it tends to be squeezed out.Due to both the compaction and flow effects, buildings tend settle. Uneven settlements, exemplified by the leaning towers in Pisa and Bologna, can have damaging effects—the building may lean, walls and partitions may crack, windows and doors may become inoperative, and, in the extreme, a building may collapse. Uniform settlements are not so serious, although extreme conditions, such as those in Mexico City, can have serious consequences. Over the past 100 years, a change in the groundwater level there has caused some buildings to settle more than 10 feet (3 meters). Because such movements can occur during and after construction, careful analysis of the behavior of soils under a building is vital.The great variability of soils has led to a variety of solutions to the foundation problem. Wherefirm soil exists close to the surface, the simplest solution is to rest columns on a small slab of concrete(spread footing). Where the soil is softer, it is necessary to spread the column load over a greater area；in this case, a continuous slab of concrete(raft or mat) under the whole building is used. In cases where the soil near the surface is unable to support the weight of the building, piles of wood, steel, or concrete are driven down to firm soil.The construction of a building proceeds naturally from the foundation up to the superstructure. The design process, however, proceeds from the roof down to the foundation (in the direction of gravity). In the past, the foundation was not subject to systematic investigation. A scientific approach to the design of foundations has been developed in the 20th century. Karl Terzaghi of the United States pioneered studies that made it possible to make accurate predictions of the behavior of foundations, using the science of soil mechanics coupled with exploration and testing procedures. Foundation failures of the past, such as the classical example of the leaning tower in Pisa, have become almost nonexistent. Foundations still are a hidden but costly part of many buildings.The early development of high-rise buildings began with structural steel framing. Reinforced concrete and stressed-skin tube systems have since been economically and competitively used in a number of structures for both residential and commercial purposes. The high-rise buildings ranging from 50 to 110 stories that are being built all over the United States are the result of innovations and development of new structural systems.Greater height entails increased column and beam sizes to make buildings more rigid so that under wind load they will not sway beyond an acceptable limit. Excessive lateral sway may causeserious recurring damage to partitions, ceilings, and other architectural details. In addition, excessive sway may cause discomfort to the occupants of the building because of their perception of such motion. Structural systems of reinforced concrete, as well as steel, take full advantage of the inherent potential stiffness of the total building and therefore do not require additional stiffening to limit the sway.中文译文建筑及高层建筑的组成1 摘要材料和结构类型是构成建筑物各方面的组成部分，这些部分包括承重结构、围护结构、楼地面和隔墙。

However, there are still two obvious disadvantages in this structure: first of all, space between two shear wall could not too big and the plane layout is not flexible, so that serviceability requirements are dissatisfied for public buildings; secondly, the bigger dead weight will lead to the increase of constructional materials and seismic force which cause desigh difficulty of super-structures and foundations. In this paper, a new type tall building structure-staggered shear wall structure-is presented in order to overcome above disadvantages of traditional shear wall, which not only provide big space for architectural design but also has lighter dead weight and high capacity of resistance to horizontal load. REINFORCEMENT CONCRETE STAGGERED SHEAR WALL STRUCTURAL SYSTEM IN TALL BUILDINGS Structure Style and Features of New Type Shear Wall Structural System：In this new-type shear wall structural system,every shear wall is at staggered location on adjacent floor, as well as adjacent shear walls are staggered with each other.One end of floor slab is supported on top edge of one shear wall; the other end of floor slab is supported on bottom edge of adjacent shear wall. The edge column and beam are set beside every shear wall. The embedded column and connected beam are set on every floor. The advantage of this structural system is its big use spacewith small span floor slab.The shear wall arrangement can be staggered or not according to use requirement, shown in Figure 1. As a result, the width of one bay is increased from L to 2L or 3L. In addition, the dead weigh of staggered shear wall is smaller than that of traditional down-to-ground shear wall, so the material cost is reduced. The structural analysis result indicates the wall amount decreases by 25% and the dead weigh decreased by 20%comparing the new-type shear wall with traditional shear wall, while both have same lateral stiffness. Two main obvious disadvantages of traditional shear wall are overcome and the use space of shear wall structures is enlarged effectively. Besides the architectural convenience, the staggered shear wall has other advantages. Although the stiffness of every shear wall is changed along vertical direction, the sum stiffness of whole structure is even along vertical direction when adjacent shear walls are set on staggered locations. The whole structural deformation is basically bending style. Form the analysis of reference,the staggered shear wall has stronger whole stiffness, less top-storey displacement(decreasing by about 58%),and less relative storey displacement comparing with traditional coupled shear wall.Under the same horizontal load, the staggered shear wall structure could effectively cut down the internal force of coupled beam and embedded column, at the same time the structural seismic performance is improved.1 2Working Mechanism of New Type Shear Wall StructureUnder the vertical load, this structure effect is the same as ordinary frame-shear wall structure, that is, the shear wall and column act together to resist the vertical load. Because thestiffness of every span shear wall is large and the deformation is small, the bending deformation and moment of columns are very small. Under lateral load, the structure deformation is uniform, thereby it can improve the whole stiffness effectively and the higher capability resisting lateral load is obtained.The main cause is the particular arrangement method of walls, which could be explained as follows: firstly, the lateralshearing force transfer mechanism is different from traditional shear wall. The lateral shearing force on top edge of shear wall is transferred to under layer floor slab though the bottom edge of wall, then to under storey adjacent shear wall through the under storey floor slab. At last, the lateral shearing force is transferred to ground floor shear wall and foundation.By this way,the lateral shearing force transfer mechanism is special, in which every floor slab transfer the lateral shearing force of itself floor and above floor.But in traditional shear wall directly. This structure makes the best use of the peculiarity that the slab stiffness is very strong to transfer and resist lateral shear. Although the shear walls are not up bottom in sequence, the slabs which has larger stiffness participate in the work transferring and resisting lateral shear force from the top to the down,from the floor middle part to edge, and from the edge to middle part in whole structure.It corresponds to a space integer structure with large lateral stiffness connected all shear walls by slabs, which have been cut in every story and span. It has been proved in author’s paper that the whole structure will occur integer-bending deformation under lateral force action,while every storey shear walls will occur integer bending without local bending. Secondly, in every piece of staggered shear wall (shown in Figure 2),the shear wall arrangement forms four large Xdiagonal brace along adcb,cfed, ehgf, gjih (dashed as shown in Figure 2).Because the shear walls forming X diagonal brace have large stiffness and strength, the X diagonal brace stiffness is strong. In addition, both the edge beams and columns around the boundary form bracing ‘frame”with large lateral stiffness. Hence, the structural integer stiffness is greatly improved.Due to the above main reasons, this structure is considered to have particular advantages compared with traditional shear wall structure in improving structural lateral stiffness. It can provide larger using space, and reduce the material, earthquake action as well as dead weight.Also, it can provide larger lateral stiffness, which will benefit the structural lateral capability. In author’s paper and in this paper the example calculating results indicates that lateral stiffness of this structure are double of coupled shear wall structure ,and nearly equal to integer shear wall structure (light small than the latter).Aseismic analysis and construction measures in a buildingexampleIn order to study dynamic characteristics and aseismic performances in this structural system, the staggered shear wall will be used as all cross walls in the large bay shear wall structure without internal longitudinal walls.Example. Thereis a nine-storey reinforcement concrete building, which is large bay shear wall struvture, shown in figure3. here,walls columns, beams, and slabs are all cast-in-situ. The thickness t=240mm is used for shear walls from 1 to 3 stories, while thickness t=200mm is used for shear walls from 4 to 9 stories. Given the section of columns of width b=500mm and depth h=600mm . Given the section of beams of width b=300mm and depth h=700mm . The modulus of elasticity is assumed tobe E=2.1*10E7kN/2m and G=1.05*10E7 kN /2m . The external longitudinal walls are cast-in-situ wall frame, and the cross walls are staggered shear walls , showm in Figure 3 (a) (scheme I) ,intensity 8 zones near earthquake, 2type site ground 。

高层结构与钢结构(中英论文翻译用) - 建筑技术高层结构与钢结构近年来，尽管一般的建筑结构设计取得了很大的进步，但是取得显著成绩的还要属超高层建筑结构设计。
最初的高层建筑设计是从钢结构的设计开始的。
钢筋混凝土和受力外包钢筒系统运用起来是比较经济的系统，被有效地运用于大批的民用建筑和商业建筑中。
50层到100层的建筑被定义为超高层建筑。
而这种建筑在美国得广泛的应用是由于新的结构系统的发展和创新。
这样的高度需要增大柱和梁的尺寸，这样以来可以使建筑物更加坚固以至于在允许的限度范围内承受风荷载而不产生弯曲和倾斜。
过分的倾斜会导致建筑的隔离构件、顶棚以及其他建筑细部产生循环破坏。
除此之外，过大的摇动也会使建筑的使用者们因感觉到这样的的晃动而产生不舒服的感觉。
无论是钢筋混凝土结构系统还是钢结构系统都充分利用了整个建筑的刚度潜力，因此不能指望利用多余的刚度来限制侧向位移。
在钢结构系统设计中，经济预算是根据每平方英寸地板面积上的钢材的数量确定的。
图示1中的曲线A显示了常规框架的平均单位的重量随着楼层数的增加而增加的情况。
而曲线B显示则显示的是在框架被保护而不受任何侧向荷载的情况下的钢材的平均重量。
上界和下界之间的区域显示的是传统梁柱框架的造价随高度而变化的情况。
而结构工程师改进结构系统的目的就是减少这部分造价。
钢结构中的体系：钢结构的高层建筑的发展是几种结构体系创新的结果。
这些创新的结构已经被广泛地应用于办公大楼和公寓建筑中。
刚性带式桁架的框架结构：为了联系框架结构的外柱和内部带式桁架，可以在建筑物的中间和顶部设置刚性带式桁架。
1974年在米望基建造的威斯康森银行大楼就是一个很好的例子。
框架筒结构：如果所有的构件都用某种方式互相联系在一起，整个建筑就像是从地面发射出的一个空心筒体或是一个刚性盒子一样。
这个时候此高层建筑的整个结构抵抗风荷载的所有强度和刚度将达到最大的效率。
这种特殊的结构体系首次被芝加哥的43层钢筋混凝土的德威特红棕色的公寓大楼所采用。

In comparison with the traditional frame structure, the high-rise shear wall structure is more transparent, spacious, it not only can effectively increase the usable floor area, and the use function of architecture is optimized, at the same time also can give owner decorate and reformed provide acertain amount of flexibility. And structurally, high-rise shear wall structure of reinforced dosage is less, strong integrity, structure stiffness is bigger also, also can be in the hotel and residential living in high-rise building, such as dividing walls by design to guest room and bedroom are divided into small, so that part of the main wall and separation wall in the process of optimizing the allocation of unity, so the economy is relatively high. This article in view of the high-rise shear wall structure optimization design was analyzed and discussed.Second、the high-rise shear wall structure optimization design and analysis1, the aseismic optimum design high-rise shear wall structureAccording to the relevant institutions to analyze the seismic record in the history of the research in China shows that after the high-rise shear wall structure will be a severe damage in the earthquake, investigate its root cause lies in the bottom layer of high-rise shear wall structure stiffness and the gap between the upper stiffness often too, once when the earthquake effect on its underlying, will lead to the underlying are striking and obvious elastic-plastic deformation. So for the high-rise shear wall structure, the underlying stiffness and the ratio of the upper stiffness must be strictly controlled, this is the most critical point. In addition, because of different regions have different seismic fortification intensity, so in for aseismic design of high-rise shear wall structure also should have to discriminate, to ensure its economic rationality.2, coupling beam of high-rise shear wall structure optimization design In the high-rise shear wall structure, even the beam energy dissipation is a key component, its shear failure will have a very adverse effect on structure seismic, and greatly reduce the ductility of the structural system. Therefore in the process of high-rise shear wall structure optimization design, it is important to note that even the beams to its strong shear weak bending calculation, to ensure even later than bending beam shear failure. To artificially increase the coupling beam longitudinal reinforcement operation must be cautious, because it may not be able to meet the requirements of its strong shear weak bending. Of course also cannot simply think that increasing stirrup must be able to ensure that the requirements of its strong shear weak bending, this is because when the beam cannot meet its cross section control condition, blindly blindly increasing stirrup will inevitably lead to the beam in the stirrup also not give full play to the role of a shear failure occurs. The shear calculation, and even the beam cross section for the coupling beam cross ratio greater than 2.5, should pay attention to increase the shear design value multiplied by coefficient.3，Long limb wall high-rise shear wall structure optimization designIn high-rise shear wall structure optimization design must also focus on which its ductility, especially for the high fine shape of shear wall (that is, the ratio of more than 2), it has good ductility and flexural failure properties, which can effectively avoid brittle shear failure. In wall limb length longer cases, however, in order to meet the every wall section of the aspect ratio of more than two, you can take the way of open hole divided wall to become independent, small and uniform wall section. In addition, when the wall section is small, the length of the cracks caused by the bending of the width is small, so you can fully play the role of the shear wall wall reinforcement. In addition to there exist much the length of the shear wall structure more than 8 meters of shear wall wall limbs, in the theoretical calculation of the floor shear force, for the most part, are made by the shear wall wall limb. So the earthquake especially when the intensity of earthquake, the wall limb is the most vulnerable to damage. And short wall limb is because not enough reinforcement, so that the complete destruction of the structure of the whole metope.4，High-rise shear wall structure layout optimizationHigh-rise shear wall structure arrangement should be as far as possible, stick to the principle of concise, rules, and ensure the structure of the center of mass is consistent with the just heart, especially of shear wall arrangement and the length of the wall limbs should be reasonable. Because the shear stiffness of high-rise shear wall structure is opposite bigger, so if complicated plane form, arrangement of wall limb is longer, it is easy to appear stress concentration, local stiffness is too large, often appear even decorate few shear wall can meet the lower level of the upper limit value of lateral stiffness ratio. So on the shear wall layout must adhere to the principle of symmetrical, uniform and surrounding, dispersion, and wall piece should not be too long, wall flat form also should not be enhanced lateral stiffness of the "t", "l", such as plane form, and graphic form should be used as "one" word. At the same time also should control the largest spacing of shear wall, to meet the requirements of specification. Longitudinal shear wall should also open out the vertical axis has been decorated humanly scaled shear wall, so it can greatly enhance the ability of its lateral rigidity, in order to avoid side column to produce too much tension and pressure. Three, endnotesTo sum up, only scientific and reasonable system of shear wall structure can effectively guarantee the safety performance, economic performance and structure of high-rise building as structure design personnel shall be in accordance with the relevant specification requirements and the need of the construction unit, to areasonable choice of the high-level structure system and optimization. And in the process of high-rise shear wall structure optimization design, the entire process of shear wall structure system arrangement and in the final analysis is a process of gradual optimization, because only when will follow the principle of uniform around the symmetrical design of high-rise shear wall structure system stiffness and deformation control in the most reasonable range, to make it play the maximum effect of the whole structural system. In addition, in the midst of high-rise shear wall structure, the effect of coupling beam cannot be underestimated, this is because even the stiffness of the beam are often the rigidity of the high-rise shear wall structure has a controlling influence, therefore in the optimal design of the high-rise shear wall structure, must not blindly increase the stiffness of one or a few structures, otherwise extremely easy to cause the weak parts of the structure system shift and even cause the emergence of a new weak positions.1、Structural use of concrete - Code of practice for design and construction BS 8110-1-19972、Coatings for fire protection of building elements - Code of practice for the selection and installation of sprayed mineral coatings BS 8202-1-19953、Electric cables - 300/500 V screened electric cables having low emission of smoke and corrosive gases when affected by fire, for use in walls, partitions and building voids Mule cables BS 8436-20044、European construction ontology (Ee) BS CWA 15142-20045、European 2.

超高层建筑结构设计与施工控制(英文中文双语版优质文档)
超高层建筑结构设计与施工控制（英文中文双语版优质文档）Super high-rise buildings are an important part of today's urbanization process, which is of great significance to the utilization of urban space and the development of building technology. Structural design and construction control of super high-rise buildings are core issues in the construction industry and important skills that architects and construction teams need to master.1. Structural design of super high-rise buildingsThe structural design of super high-rise buildings is one of the core skills that architects need to master. The structural design of a super high-rise building needs to take into account external factors such as the height of the building, earthquakes, wind, etc., and at the same time meet the strength and stability requirements of the building. Architects need to comprehensively consider factors such as the purpose of the building, design requirements and site conditions, and design a structural form suitable for the building.The key to the structural design of super high-rise buildings lies in the control of strength and stability. Architects need to choose different structural forms according to different building heights and external environmental factors, including steel structures, concrete structures, frame structures, etc., while taking into account the rationality and feasibility of the structure to ensure the safety and stability of the structure.2. Super high-rise building construction controlConstruction control of supertall buildings is another important skill that architects and construction teams need to master. During the construction process, various factors such as the height of the building, external environmental factors, the use of manpower and mechanical equipment need to be considered to ensure the quality and safety of the construction.The key to super high-rise building construction control lies in the control of safety and efficiency. The construction team needs to formulate reasonable construction plans and safety measures to ensure safety and quality control during the construction process. At the same time, the improvement of construction efficiency must be considered to ensure the rationality of the construction period and the progress of the project.3. Innovation and application of super high-rise building structure design and construction controlWith the continuous development of construction technology and materials, the structural design and construction control of super high-rise buildings are also constantly innovated and applied. For example, through the application of digital technology and intelligent equipment, the efficiency and precision of building structure design and construction control can be greatly improved; through the application of new materials, the safety and sustainability of buildings can be improved.In addition, the structural design and construction control of super high-rise buildings also need to consider the application of human factors. Architects and construction teams need to consider the users of the building, as well as the impact of the building on the surrounding environment and urban space, and improve the use value of the building and its contribution to the urban environment by designing a humanized building structure and construction plan.In conclusion, the structural design and construction control of super high-rise buildings are the core issues in the construction industry, which requires professional knowledge and skills of architects and construction teams. Through continuous innovation and application of new technologies, new materials and humanized design concepts, the safety, sustainability and use value of super high-rise buildings can be improved, while contributing to the urbanization process and the development of building technology.超高层建筑是当今城市化进程中的重要组成部分，对于城市空间的利用和建筑技术的发展具有重要的意义。

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。

High-rise Structures and Steel StructuresThe application of steel structures can effectively improve the stability and seismic performance of high-rise buildings. Due to the height and self-weight of high-rise buildings, they are prone to generate significant loads, which pose higher requirements for structural stability. Steel structures have excellent rigidity and joint performance, allowing them to bear and distribute these loads effectively, providing stable structural support. Additionally, steel structures have good seismic performance, effectively reducing damage and destruction caused by vibrations to the buildings.The fast construction speed of steel structures can effectively shorten the project duration, enhancing the economic benefits of projects. The construction period of high-rise buildings is typically long, leading to increased project costs and reduced profits. However, the manufacturing and installation processes of steel structures are relatively simple, enabling rapid assembly and installation, thus significantly reducing the construction period of high-rise buildings. Additionally, steelstructure materials have high recyclability, reducing the production of construction waste, minimizing environmental impact, and improving project sustainability.。

外文翻译题目：高层建筑学院土木建筑工程学院专业土木工程（建筑工程方向）班级学号姓名指导教师Tall BuildingsAlthough there have been many advancements in building construction technology in general, spectacular achievements have been made in the design and construction of ultrahigh-rise buildings.The early development of high-rise buildings began with structural steel framing. Reinforced concrete and stressed-skin tube systems have since been economically and competitively used in a number of structures for both residential and commercial purposes. The high-rise buildings ranging from 50 to 110 stories that are being built all over the United States are the result of innovations and development of new structural systems.Greater height entails increased column and beam sizes to make buildings more rigid so that under wind load they will not sway beyond an acceptable limit. Excessive lateral sway may cause serious recurring damage to partitions, ceilings, and other architectural details. In addition, excessive sway may cause discomfort to the occupants of the building because of their perception of such motion. Structural systems of reinforced concrete, as well as steel, take full advantage of the inherent potential stiffness of the total building and therefore do not require additional stiffening to limit the sway.In a steel structure, for example, the economy can be defined in terms of the total average quantity of steel per square foot of floor area of the building. Curve A in Fig. 1 represents the average unit weight of a conventional frame with increasing numbers of stories. Curve B represents the average steel weight if the frame is protected from all lateral loads. The gap between the upper boundary and the lower boundary represents the premium for height for the traditional column-and-beam frame; Structural engineers have developed structural systems with a view to eliminating this premium.Systems in steel. Tall buildings in steel developed as a result of several types of structural innovations. The innovations have been applied to the construction of both office and apartment buildings.Frames with rigid belt trusses. In order to tie the exterior columns of a frame structure to the interior vertical trusses, a system of rigid belt trusses at mid-height and at the top of the building may be used. A good example of this system is the First Wisconsin Bank Building (1974) in Milwaukee.Framed tube. The maximum efficiency of the total structure of a tall building, for bothstrength and stiffness, to resist wind load can be achieved only if all column elements can be connected to each other in such a way that the entire building acts as a hollow tube or rigid box in projecting out of the ground. This particular structural system was probably used for the first time in the 43-story reinforced concrete DeWitt Chestnut Apartment Building in Chicago. The most significant use of this system is in the twin structural steel towers of the 110-story World Trade Center building in New York.Column-diagonal truss tube. The exterior columns of a building can be spaced reasonably far apart and yet be made to work together as a tube by connecting them with. Diagonal members intersecting at the center line of the columns and beams. This simple yet extremely efficient system was used for the first time on the John Hancock Center in Chicago, using as much steel as is normally needed for a traditional story building.Fig. 1. Graphical relationship between design quantities of steel and building heights for a typical building frame. Curves A and B correspond to the boundary conditions indicated in the two building diagrams. 1 psf = 0. 048kPa.Bundled tube. With the continuing need for larger and taller buildings, the framed tube or the column-diagonal truss tube may be used in a bundled form to create larger tube envelopes while maintaining high efficiency. The i10-story Sears Roebuck Headquarters Building in Chicago has nine tubes, bundled at tile base of the building in three rows. Some of these individual tubes terminate at different heights of the building, demonstrating the unlimited architectural possibilities of this latest structural concept. The Sears tower, at a height of 1450 ft (442 m), is the world's tallest building.Stressed-skin tube system. The tube structural system was developed for improving the resistance to lateral forces (wind or earthquake) and the control of drift (lateral building movement) in high-rise building. The stressed-skin tube takes the tube system a step further. The development of the stressed-skin tube utilizes the facade of the building as a structural element which acts with the framed tube, thus providing an efficient way of resisting lateral loads in high-rise buildings, and resulting in cost-effective column-free interior space with a high ratio of net to gross floor area.Because of the contribution of the stressed-skin facade, the framed members of the tube require less mass, and are thus lighter and less expensive. All the typical columns and spandrel beams are standard rolled shapes, minimizing the use and cost of special built-up members. The depth requirement for the perimeter spandrel beams is also reduced, and the need for upset beams above floors, which would encroach on valuable space, is minimized. The structural system has been used on the 54-story One Mellon Bank Center in Pittsburgh.Systems in concrete. While tall buildings constructed of steel had an early start, development of tall buildings of reinforced concrete progressed at a fast enough rate to provide a competitive challenge to structural steel systems for both office and apartment buildings.Framed tube. As discussed above, the first framed tube concept for tall buildings was used for the 43-story DeWitt Chestnut Apartment Building. In this building, exterior columns were spaced at 5.5-ft (1.68-m) centers, and interior columns were used as needed to support the 8-in.-thick (20-cm) flat-plate concrete slabs.Tube in tube. Another system in reinforced concrete for office buildings combines the traditional shear wall construction with an exterior framed tube. The system consists of an outer framed tube of very closely spaced columns and an interior rigid shear wall tube enclosing the central service area. The system (Fig.2), known as the tube-in-tube system, made it possible to design the world's present tallest (714 ft or 218m) lightweight concrete Building in Houston)for structure of only 35 s oriel building the unit 52—story One Shell Plaza of a traditional shear wallSystems compiling both concrete and steel have also been developed，an example of which is the composite system developed by Skidmore，Owings & Merrill in which an exterior closely spaced framed tube in concrete envelops an interior steel framing，thereby combining the advantages of both reinforced concrete and structuralsteel systems．The 52—story One Shell Square Building in New Orleans is based on this system．NEW WORDS AND PHRASES1．spectacular 壮观的，惊人的，引人注意的2．sway 摇动，摇摆，歪，使倾斜3．residential 居住的，住宅的，作住家用的4．commercial 商业的，商业上的，商务的5．innovation 革新，创新，新方法，新事物6．boundary 分界线，边界7．eliminate 排除，消除，除去8．apartment 公寓住宅，单元住宅9．column 柱，支柱，圆柱，柱状物10．demonstrate 示范，证明，演示，11．project 凸出，投射，计划，工程12．stress 应力，压力13．truss 构架，桁架14．bundle 捆，束，包15．terminate 使终止，使结尾，结束16．facade (房屋的)／E面，立面，表面17．perimeter 周，周围，周界，周长18．encroach 侵犯，侵占，蚕食19．high·rise building 高层建筑20．reinforced concrete 钢筋混凝土21．spandrel beam 窗下墙的墙托梁22．shear wall 剪力墙高层建筑大体上建筑施工工艺学方面已经有许多进步, 在超高层的设计和施工上已经取得了惊人的成就。

中英文对照外文翻译文献(文档含英文原文和中文翻译)Structural Systems to resist lateral loadsmonly Used structural SystemsWith loads measured in tens of thousands kips, there is little room in the design of high-rise buildings for excessively complex thoughts. Indeed, the better high-rise buildings carry the universal traits of simplicity of thought and clarity of expression.It does not follow that there is no room for grand thoughts. Indeed, it is with such grand thoughts that the new family of high-rise buildings has evolved. Perhaps more important, the new concepts of but a few years ago have become commonplace in today’ s technology.Omitting some concepts that are related strictly to the materials of construction, the most commonly used structural systems used in high-rise buildings can be categorized as follows:1.Moment-resisting frames.2.Braced frames, including eccentrically braced frames.3.Shear walls, including steel plate shear walls.4.Tube-in-tube structures.5.Tube-in-tube structures.6.Core-interactive structures.7.Cellular or bundled-tube systems.Particularly with the recent trend toward more complex forms, but in response also to the need for increased stiffness to resist the forces from wind and earthquake, most high-rise buildings have structural systems built up of combinations of frames, braced bents, shear walls, and related systems. Further, for the taller buildings, the majorities are composed of interactive elements in three-dimensional arrays.The method of combining these elements is the very essence of the design process for high-rise buildings. These combinations need evolve in response to environmental, functional, and cost considerations so as to provide efficient structures that provoke the architectural development to new heights. This is not to say that imaginative structural design can create great architecture. To the contrary, many examples of fine architecture have been created with only moderate support from the structural engineer, while only fine structure, not great architecture, can be developed without the genius and the leadership of a talented architect. In any event, the best of both is needed to formulate a truly extraordinary design of a high-rise building.While comprehensive discussions of these seven systems are generally available in the literature, further discussion is warranted here .The essence of the design process is distributed throughout the discussion.2.Moment-Resisting FramesPerhaps the most commonly used system in low-to medium-rise buildings, the moment-resisting frame, is characterized by linear horizontal and vertical members connected essentially rigidly at their joints. Such frames are used as a stand-alone system or in combination with other systems so as to provide the needed resistance to horizontal loads. In the taller of high-rise buildings, the system is likely to be found inappropriate for a stand-alone system, this because of the difficulty in mobilizing sufficient stiffness under lateral forces.Analysis can be accomplished by STRESS, STRUDL, or a host of other appropriatecomputer programs; analysis by the so-called portal method of the cantilever method has no place in today’s technology.Because of the intrinsic flexibility of the column/girder intersection, and because preliminary designs should aim to highlight weaknesses of systems, it is not unusual to use center-to-center dimensions for the frame in the preliminary analysis. Of course, in the latter phases of design, a realistic appraisal in-joint deformation is essential.3.Braced FramesThe braced frame, intrinsically stiffer than the moment –resisting frame, finds also greater application to higher-rise buildings. The system is characterized by linear horizontal, vertical, and diagonal members, connected simply or rigidly at their joints. It is used commonly in conjunction with other systems for taller buildings and as a stand-alone system in low-to medium-rise buildings.While the use of structural steel in braced frames is common, concrete frames are more likely to be of the larger-scale variety.Of special interest in areas of high seismicity is the use of the eccentric braced frame.Again, analysis can be by STRESS, STRUDL, or any one of a series of two –or three dimensional analysis computer programs. And again, center-to-center dimensions are used commonly in the preliminary analysis.4.Shear wallsThe shear wall is yet another step forward along a progression of ever-stiffer structural systems. The system is characterized by relatively thin, generally (but not always) concrete elements that provide both structural strength and separation between building functions.In high-rise buildings, shear wall systems tend to have a relatively high aspect ratio, that is, their height tends to be large compared to their width. Lacking tension in the foundation system, any structural element is limited in its ability to resist overturning moment by the width of the system and by the gravity load supported by the element. Limited to a narrow overturning, One obvious use of the system, which does have the needed width, is in the exterior walls of building, where the requirement for windows is kept small.Structural steel shear walls, generally stiffened against buckling by a concrete overlay, have found application where shear loads are high. The system, intrinsically more economicalthan steel bracing, is particularly effective in carrying shear loads down through the taller floors in the areas immediately above grade. The sys tem has the further advantage of having high ductility a feature of particular importance in areas of high seismicity.The analysis of shear wall systems is made complex because of the inevitable presence of large openings through these walls. Preliminary analysis can be by truss-analogy, by the finite element method, or by making use of a proprietary computer program designed to consider the interaction, or coupling, of shear walls.5.Framed or Braced TubesThe concept of the framed or braced or braced tube erupted into the technology with the IBM Building in Pittsburgh, but was followed immediately with the twin 110-story towers of the World Trade Center, New York and a number of other buildings .The system is characterized by three –dimensional frames, braced frames, or shear walls, forming a closed surface more or less cylindrical in nature, but of nearly any plan configuration. Because those columns that resist lateral forces are placed as far as possible from the cancroids of the system, the overall moment of inertia is increased and stiffness is very high.The analysis of tubular structures is done using three-dimensional concepts, or by two- dimensional analogy, where possible, whichever method is used, it must be capable of accounting for the effects of shear lag.The presence of shear lag, detected first in aircraft structures, is a serious limitation in the stiffness of framed tubes. The concept has limited recent applications of framed tubes to the shear of 60 stories. Designers have developed various techniques for reducing the effects of shear lag, most noticeably the use of belt trusses. This system finds application in buildings perhaps 40stories and higher. However, except for possible aesthetic considerations, belt trusses interfere with nearly every building function associated with the outside wall; the trusses are placed often at mechanical floors, mush to the disapproval of the designers of the mechanical systems. Nevertheless, as a cost-effective structural system, the belt truss works well and will likely find continued approval from designers. Numerous studies have sought to optimize the location of these trusses, with the optimum location very dependent on the number of trusses provided. Experience would indicate, however, that the location of these trusses is provided by the optimization of mechanical systems and by aesthetic considerations,as the economics of the structural system is not highly sensitive to belt truss location.6.Tube-in-Tube StructuresThe tubular framing system mobilizes every column in the exterior wall in resisting over-turning and shearing forces. The term‘tube-in-tube’is largely self-explanatory in that a second ring of columns, the ring surrounding the central service core of the building, is used as an inner framed or braced tube. The purpose of the second tube is to increase resistance to over turning and to increase lateral stiffness. The tubes need not be of the same character; that is, one tube could be framed, while the other could be braced.In considering this system, is important to understand clearly the difference between the shear and the flexural components of deflection, the terms being taken from beam analogy. In a framed tube, the shear component of deflection is associated with the bending deformation of columns and girders (i.e, the webs of the framed tube) while the flexural component is associated with the axial shortening and lengthening of columns (i.e, the flanges of the framed tube). In a braced tube, the shear component of deflection is associated with the axial deformation of diagonals while the flexural component of deflection is associated with the axial shortening and lengthening of columns.Following beam analogy, if plane surfaces remain plane (i.e, the floor slabs),then axial stresses in the columns of the outer tube, being farther form the neutral axis, will be substantially larger than the axial stresses in the inner tube. However, in the tube-in-tube design, when optimized, the axial stresses in the inner ring of columns may be as high, or even higher, than the axial stresses in the outer ring. This seeming anomaly is associated with differences in the shearing component of stiffness between the two systems. This is easiest to under-stand where the inner tube is conceived as a braced (i.e, shear-stiff) tube while the outer tube is conceived as a framed (i.e, shear-flexible) tube.7.Core Interactive StructuresCore interactive structures are a special case of a tube-in-tube wherein the two tubes are coupled together with some form of three-dimensional space frame. Indeed, the system is used often wherein the shear stiffness of the outer tube is zero. The United States Steel Building, Pittsburgh, illustrates the system very well. Here, the inner tube is a braced frame, the outer tube has no shear stiffness, and the two systems are coupled if they were considered as systemspassing in a straight line from the “hat” structure. Note that the exterior columns would be improperly modeled if they were considered as systems passing in a straight line from the “hat” to the foundations; these columns are perhaps 15% stiffer as they follow the elastic curve of the braced core. Note also that the axial forces associated with the lateral forces in the inner columns change from tension to compression over the height of the tube, with the inflection point at about 5/8 of the height of the tube. The outer columns, of course, carry the same axial force under lateral load for the full height of the columns because the columns because the shear stiffness of the system is close to zero.The space structures of outrigger girders or trusses, that connect the inner tube to the outer tube, are located often at several levels in the building. The AT&T headquarters is an example of an astonishing array of interactive elements:1.The structural system is 94 ft (28.6m) wide, 196ft(59.7m) long, and 601ft (183.3m)high.2.Two inner tubes are provided, each 31ft(9.4m) by 40 ft (12.2m), centered 90 ft (27.4m)apart in the long direction of the building.3.The inner tubes are braced in the short direction, but with zero shear stiffness in the longdirection.4. A single outer tube is supplied, which encircles the building perimeter.5.The outer tube is a moment-resisting frame, but with zero shear stiffness for thecenter50ft (15.2m) of each of the long sides.6. A space-truss hat structure is provided at the top of the building.7. A similar space truss is located near the bottom of the building8.The entire assembly is laterally supported at the base on twin steel-plate tubes, becausethe shear stiffness of the outer tube goes to zero at the base of the building.8.Cellular structuresA classic example of a cellular structure is the Sears Tower, Chicago, a bundled tube structure of nine separate tubes. While the Sears Tower contains nine nearly identical tubes, the basic structural system has special application for buildings of irregular shape, as the several tubes need not be similar in plan shape, It is not uncommon that some of the individual tubes one of the strengths and one of the weaknesses of the system.This special weakness of this system, particularly in framed tubes, has to do with the concept of differential column shortening. The shortening of a column under load is given by the expression△=ΣfL/EFor buildings of 12 ft (3.66m) floor-to-floor distances and an average compressive stress of 15 ksi (138MPa), the shortening of a column under load is 15 (12)(12)/29,000 or 0.074in (1.9mm) per story. At 50 stories, the column will have shortened to 3.7 in. (94mm) less than its unstressed length. Where one cell of a bundled tube system is, say, 50stories high and an adjacent cell is, say, 100stories high, those columns near the boundary between .the two systems need to have this differential deflection reconciled.Major structural work has been found to be needed at such locations. In at least one building, the Rialto Project, Melbourne, the structural engineer found it necessary to vertically pre-stress the lower height columns so as to reconcile the differential deflections of columns in close proximity with the post-tensioning of the shorter column simulating the weight to be added on to adjacent, higher columns.抗侧向荷载的结构体系1.常用的结构体系若已测出荷载量达数千万磅重，那么在高层建筑设计中就没有多少可以进行极其复杂的构思余地了。

中英文资料翻译一.英文原文A NEW STAGGERED SHEAR WALL STRUCTURE FOR HIGH-RISE BUILDINGABSTRACTShear wall structure has been widely used in tall buildings. However, there are still two obvious disadvantages in this structure: first of all, space between two shear wall could not too big and the plane layout is not flexible, so that serviceability requirements are dissatisfied for public buildings; secondly, the bigger dead weight will lead to the increase of constructional materials and seismic force which cause desigh difficulty of super-structures and foundations. In this paper, a new type tall building structure-staggered shear wall structure-is presented in order to overcome above disadvantages of traditional shear wall, which not only provide big space for architectural design but also has lighter dead weight and high capacity of resistance to horizontal load. REINFORCEMENT CONCRETE STAGGERED SHEAR WALL STRUCTURAL SYSTEM IN TALL BUILDINGS Structure Style and Features of New Type Shear Wall Structural System：In this new-type shear wall structural system,every shear wall is at staggered location on adjacent floor, as well as adjacent shear walls are staggered with each other.One end of floor slab is supported on top edge of one shear wall; the other end of floor slab is supported on bottom edge of adjacent shear wall. The edge column and beam are set beside every shear wall. The embedded column and connected beam are set on every floor. The advantage of this structural system is its big use space with small span floor slab.The shear wall arrangement can be staggered or not according to use requirement, shown in Figure 1. As a result, the width of one bay is increased from L to 2L or 3L. In addition, the dead weigh of staggered shear wall is smaller than that of traditional down-to-ground shear wall, so the material cost is reduced. The structural analysis result indicates the wall amount decreases by 25% and the dead weigh decreased by 20%comparing the new-type shear wall with traditional shear wall, while both have same lateral stiffness. Two main obvious disadvantages of traditional shear wall are overcome and the use space of shear wall structures is enlarged effectively. Besides the architectural convenience, the staggered shear wall has other advantages. Although the stiffness of every shear wall is changed along vertical direction, the sum stiffness of whole structure is even along vertical direction when adjacent shear walls are set on staggered locations. The whole structural deformation is basically bending style. Form the analysis of reference,the staggered shear wall has stronger whole stiffness, less top-storey displacement(decreasing by about 58%),and less relative storey displacement comparing with traditional coupled shear wall.Under the same horizontal load, the staggered shear wall structure could effectively cut down the internal force of coupled beam and embedded column, at the same time the structural seismic performance is improved.1 2Working Mechanism of New Type Shear Wall StructureUnder the vertical load, this structure effect is the same as ordinary frame-shear wall structure, that is, the shear wall and column act together to resist the vertical load. Because the stiffness of every span shear wall is large and the deformation is small, the bending deformation and moment of columns are very small. Under lateral load, the structure deformation is uniform, thereby it can improve the whole stiffness effectively and the higher capability resisting lateral load is obtained.The main cause is the particular arrangement method of walls, which could be explained as follows: firstly, the lateralshearing force transfer mechanism is different from traditional shear wall. The lateral shearing force on top edge of shear wall is transferred to under layer floor slab though the bottom edge of wall, then to under storey adjacent shear wall through the under storey floor slab. At last, the lateral shearing force is transferred to ground floor shear wall and foundation.By this way,the lateral shearing force transfer mechanism is special, in which every floor slab transfer the lateral shearing force of itself floor and above floor.But in traditional shear wall directly. This structure makes the best use of the peculiarity that the slab stiffness is very strong to transfer and resist lateral shear. Although the shear walls are not up bottom in sequence, the slabs which has larger stiffness participate in the work transferring and resisting lateral shear force from the top to the down,from the floor middle part to edge, and from the edge to middle part in whole structure.It corresponds to a space integer structure with large lateral stiffness connected all shear walls by slabs, which have been cut in every story and span. It has been proved in author’s paper that the whole structure will occur integer-bending deformation under lateral force action,while every storey shear walls will occur integer bending without local bending. Secondly, in every piece of staggered shear wall (shown in Figure 2),the shear wall arrangement forms four large X diagonal brace along adcb,cfed, ehgf, gjih (dashed as shown in Figure 2).Because the shear walls forming X diagonal brace have large stiffness and strength, the X diagonal brace stiffness is strong. In addition, both the edge beams and columns around the boundary form bracing ‘frame”with large lateral stiffness. Hence, the structural integer stiffness is greatly improved.Due to the above main reasons, this structure is considered to have particular advantages compared with traditional shear wall structure in improving structural lateral stiffness. It can provide larger using space, and reduce the material, earthquake action as well as dead weight.Also, it can provide larger lateral stiffness, which will benefit the structural lateral capability. In author’s paper and in this paper the example calculating results indicates that lateral stiffness of this structure are double of coupled shear wall structure ,and nearly equal to integer shear wall structure (light small than the latter).Aseismic analysis and construction measures in a buildingexampleIn order to study dynamic characteristics and aseismic performances in this structural system, the staggered shear wall will be used as all cross walls in the large bay shear wall structure without internal longitudinal walls.Example. Thereis a nine-storey reinforcement concrete building, which is large bay shear wall struvture, shown in figure3. here,walls columns, beams, and slabs are all cast-in-situ. The thickness t=240mm is used for shear walls from 1 to 3 stories, while thickness t=200mm is used for shear walls from 4 to 9 stories.

The modulus of elasticity is assumed to be E=2.1*10E7kN/2m and G=1.05*10E7 kN /2m .

Recent renowned projects like the 50-storey Manulife Tower, the 62-storey Cheung Kong Center, the 80-storey “Center”,the 88-storey International Financial Center, and a number of recent residential buildings exceeding 60-storey tall, are without exception, using curtain wall as their external envelope.Using thin wall as external envelope for tall buildings has always been a challenge to designers and builders, in particular in terms of cost, energy, water-tightness, installation, dimensional and structural stability, interfacing arrangement with other building components and maintenance etc. Making use of the Hong Kong’s experience, the writer wish to highlight some local practices and summarize how such thin wall systems are designed and installed.USING CURTAIN WALL IN BUILDIGNS OF HONG KONGHigh-rise buildings started to spring up in the skyline of Hong Kong since the 1970’s in parallel with her economic take-off from a traditional manufacturing-based industrial economy and transforming herself into an world-renowned international financial centre. High-rise buildings by that time were concentrated in the commercial districts like Central in the Hong Kong Island and Tsim Sha Tsui on the Kowloon Peninsula side.The first generation of buildings using what-so-called a curtain wall system can hardly be described as a full system which is usually of proprietary design. The pioneer systems were just external façade/walling designed by local architects and with materials supplied by localmanufacturers. The common systems used by that time were in majority stick-type, spandrel and cover, or unit-in-frame systems, constructed of aluminum sections, sometimes incorporated with large areas of stone slabs to cover up solid walls. They were popular due to their highly adaptability, low cost, easy to design-and-install nature.More deluxe commercial buildings were built in the late 70’s as the economy of Hong Kong growing hotter and hotter. Developers tended to request for systems with higher performance as the external envelop for their buildings, in terms both of appearance, material, construction and maintenance concerns.Due to the relative lack of experience at that stage, the performance of these second generation curtain wall systems (from late 70’s to mid 80’s)could still hardly described as satisfactory. Problems like seepage, staining, deformation, deterioration and rapid aging of the jointing materials, were very common to many walling cases, often to a condition that made repair and maintenance almost impossible. The replacement of these walling systems not only costly, but also created great disruption to the normal utilization of the building users, and at the same time badly lowered the property value of the entire premises.The third generation of curtain wall systems roughly started in the mid/late 80’s, by the time Hong Kong was experiencing her economic climax before the handing over of her sovereignty backto China in 1997. Accommodated experience in the application of curtain wall systems in high-performance buildings contributed solidly in the process of perfecting these systems. Throughout the period, the design and production teams, as well as the manufacturers and the engineering supporting teams, were growing more mature in the mastering of the local situation and market. Most problems appeared in the previous cases have been much effectively taken care of. Systems of this generation are in general much more satisfactorily received by most users.WHAT IS A CURTAIN WALLMetal and glass curtain wall systems have found growing favour in modern architecture. They are easily distinguished from other types of claddings by their thin mullions of horizontal and vertical metallic bars surrounding an all glass or metal panel. The curtain wall system has evolved rapidly over the last two decades, especially with respect to weather control performance. The early systems presented frequent rain penetration problems; water stain patches would form on the outside or condensation on the inside mullion surfaces; glazing seals were sometimes pumped out of the rabbet of sealed double glazing window units. However, most of these difficulties were eventually overcome with improved detail design of the system components. Today, most curtain wall manufacturers offer a quality product line of components which can be used to create one of the best overall exterior wall systems.A curtain wall system is a lightweight exterior cladding which is hung on the building structure, usually from floor to floor. It can provide a variety of exterior appearances but is characterized by narrowly spaced vertical and horizontal caps with glass or metal infill panels. These systems provide a finished exterior appearance and most often a semi-finished interior as well. They are also designed to accommodate structural deflections, control wind-driven rain and air leakage, minimize the effects of solar radiation and provide for maintenance-free long term performance. Most of today's metal curtain wall systems are constructed of lightweight aluminum or its alloys, althoughsome may be of steel.COMMON TYPES OF CURTAIN WALL SYSTEMSExternal wall with large area of glazed portion that carries no superimposed load except wind load is usually termed as curtain wall. Traditionally curtain wall consists of a metal frame system infill with vision or opaque panels, that serves to provide glazing for window openings as well as to cover-up structures like columns, slabs and beams, or sometimes even sections of solid wall.There are many ways to serve the purpose, depending on a number of factors such as the design and budget for the project, layout and shape of the building structure, as well as other architectural or structural requirements. According to the American Architectural Manufacturers Association, curtain wall systems can be classified in five types, namely, the stick system, unit system, unit and mullion system, panel system, and the column-cover-and-spandrel system. However, due to the introduction of high-performance framing/articulation products and high-strength structural glass, some newer forms of curtain wall systems such as large-area glazed wall using spider clips, bow mullions, hangers or cable stiffeners as supports and connections, are new systems that cannot easily be classified using traditional concepts.Stick systemCurtain wall in stick system is a cladding and exterior wall system which is hung on the building structure from floor to floor. It is assembled from various components to include steel or aluminum anchors, mullions (vertical load taking member), rails vision glass, spandrel panels, insulation and metal backing pans. For the fixing of the system, there are various hardware components such as anchors, connectors, brackets, cramps, setting blocks, corner blocks, gaskets and sealants etc.This system has the following merits/demerits:Merits-Low cost, components can be made in standard design and stocked as proprietary product for use in bulk quantity.-Shorter time for design and fabrication.-Fairly easy to fit the shape and form of a building.-Require relatively simple sections to form the mullions and the backing frame.-The design of the infilling panels can be very flexible and form various combination using different materials to provide the appearance or fulfill other functional requirements.-With the provision of the spandrel panel (the opaque portion) in the design, more colour or design options can be achieved.-Installation of the system only requires simple tool like a manually operated pulley set-up.-Easier to carry out replacement, alteration and maintenance. Demerits-System is designed on a job-by-job basis-More labour-intensive in the fixing and installation process-Higher risk of leaking due to the existence of large amount of in-situ joints between mullion and panels.-Involvement of large number of framing members coming from the mullion, transom or other framing parts that make the fixing at spot quite troublesome and inconsistent.-Less fashionable for the design limited basically to monotonous grid without the elegance that other systems may achieve.Unit SystemUnit systems are composed of modulated panels that are fabricated in factory and delivered to site in one-piece for installation. The panels are fully provided with all the glazing and/or the spandrel panels, incorporated with the required insulation and other architectural features, thus requiring very limited second-fixed installation works on site. The panels are usually spanned in a floor-to-floor arrangement and may be designed in a number of standard/optional panels such as fully glazed, glazed with opaque panels, fully opaque in metal or stone slab, louvered panels, or other special modules like the corner or bayed units. In order to get the best benefit of using this system, units are often produced to an optimistic large size so as to minimize the number of units used.This system has the following merits/demerits:Merits-Easy to install merely by securing the modulated panels onto the building exterior using fixing/connection devices which are usually very dimensionally flexible.-Saving up a lot of manpower due to ease of installation.-Higher performance units can be produced to meet stringent requirements due to bettercontrol under factory environment.-Preferably to be used in buildings with large walling area for the economy of scale in production as well as the elimination of countless assembly of minor components on site. Demerits-It takes longer lead time to carry out the coordination, design and fabrication of the system/units.-Require higher dimensional accuracy in the building structure for the fixing of the units.-Lifting appliances may be required to assist the hoisting and installation of the large-sized walling units-Difficult to carry out replacement or maintenance due to the interlocking nature of the modulated units.Unit and mullion systemThis is a combination of the stick system and the unit system and may be regarded as a compromise of the two. It is more suitable for use in medium-sized projects so as to balance the factors of lead time, ease of installation and economy of scale.Panel systemA panel curtain wall system is similar to a unit system, the difference being that a panel system has homogeneous sheet or cast panel with few joints and may not have separate mullions. Unit systems are made up of smaller components fabricated together to form much complex panels that capable to perform heavier duties or other more specific requirements. However, due to the relative simplicity of the system, curtain wall of panel system design may not be able to fulfill the usual requirements most high-rise buildings required under Hong Kong’s environment. Its use is therefore more limited to certain kinds of buildings like those of standardized design for low-income classes or for buildings of industrial purposes. In this case, the panels can be constructed of sheet materials and manufactured in large quantity in very low cost.Column-cover-and-spandrel systemColumn-cover-and-spandrel system consists of column covers, which are usually made of alloyed aluminum, metal sheet or other laminated/fibre-reinforced sheet, and with glazing components and spandrel panels that fit between them. It resembles certain similarity to a unit-and-mullion system except that the structure of the building is exemplified by the column covers.With the exception of the stick system and the unit system, other curtain wall systems are seldom used in Hong Kong.Structural glazing systemThe merit of using structural glazing system as external wall is to minimize the unglazed elements as much as possible, leaving glass panel almost as the only glazed surface on the wall. This can be done by providing larger mullion supports which span outward away frm the structural floor of a building. Special clamping devices such as a spider bracket can be used to hold the glazing panel in position. Structural sealant is used to seal up the gap between the glazing panels.DESIGN PRINCIPLES FOR EXTERNAL WALLA building enclosure may be broadly defined as a set of interconnecting elements which separate the outside from the inside. These elements would include exterior walls, a roof, other components such as windows and doors, and sometimes exposed floors. The function of a building enclosure is to control the penetration of snow, wind, rain and sun to the inside and to contain the desired indoor climate. The enclosure must meet many individual requirments but for the purpose of this paper they are limited to the following six:control of air flow,control of heat flow,control over the entry of rain and snow,control of sunlight and other forms of radiant energy,control of water vapour diffusion,accommodation of building movements.The requirement for air tightness and consequently air leakage control is met by most curtain wall systems because the air barrier of the wall is inherent in the structural properties of glass and aluminum or steel tubes that comprise the system. The continuity of the air barrier (Figure 1) is achieved by the continuity of the glass panel through the air seal at the shoulder flanges of the tubular mullion, and through the aluminum section to the other flange surface. The air seal between the lower shoulder flange of the curtain wall mullion and the metal pan of the spandrel panel provides continuity of air tightness to the air barrier metal pan and on to the next mullion connection. Such assemblies are regularly tested using air pressure to determine the structural properties of the glass, metal, and seals and to determine the equivalent leakage area (ELA) that remains. In addition, the Architectural Aluminium Manufacturers Association imposes upon its members many other requirements including a specification that the system must not leak more than.30L/sperm2 of wall at a pressure difference equivalent to a 40 km/h wind.Thermal Insulation (Control of heat flow)The control of heat flow is generally achieved through the use of insulation. Although it is not apparent from the exterior, the curtain wall system uses considerable insulation usually behind spandrel glass or any opaque panels. Because of the materials used in the structure, i.e., glass and metal, which are highly conductive, the system must also contend with potential condensation on the interior surfaces. To curtail this effect, most curtain wall systems incorporate two distinct features: first, a sealed double glazed window or an insulated metal pan and second, a thermally broken mullion, usually with a PVC plastic insert and more recently, a foamed-in-place polyurethane connection. A sealed double glazed window unit can accommodate an indoor humidity up to about 35% at an outdoor temperature of -25 ° C with little condensation appearing on the glass. Similarly, the thermal break in the aluminum or steel mullion ensures that the surfacetemperature of the structural mullion will remain well above the dew point temperature of the air for most building types, except for high humidity indoor environments such as in swimming pools or computer centers. The thermal break also ensures that the structural mullion is thermally stable, that is, not subject to extremes of expansion and contraction.MAINTENANCE CONSIDERATIONMaintenance for curtain wall is a long-term consideration involving both the quality of design, control during construction and adequate maintenance throughout the life span. Once failure occurs in the curtain wall it will be very expensive to have the defects rectified and at the same time causing great disturbance to the building users. Below are some common problem sources where failures usually occur.1.D esign failure – selection and appropriateness of the system, non-compliance to design and performance standards, imperfection in the jointing design and detailing, improper use of materials etc.2.C onstruction and structural failure –wrong location or method of fixing, improper anchorage and connection provision (including failure in welding), failure in the walling components, unpredicted deflection or deformation appears in the background structure, poor supervision and workmanship.3.A ging and deterioration –discolouring and surface damaging due to weather action; corrosion due to air pollution, acid rain, or electro-chemical effect to dissimilar metals; aging and hardening of the glazing compound or sealing gasket, deteriorating of the insulating materials that lead to further dampening of the walling materials/components, disfiguring or loosening of the fixing and connections, loosening or broken-off of the glazing or other fitting items.Curtain wall systems should be inspected regularly after they have been installed in buildings. Proper maintenance and repair are essential to keep them in a safe condition. Inspectionarrangement should be made in particularly before and after typhoons. The below signs are recommended to observe closely during each inspection.-Sign of distress and deterioration of the entire wall system,-cracked, loose or missing glass panels,-bulging, bowing, separation, delamination, rotation, displacement of panels,-marks of water, staining and rust,-damaged and missing parts, corrosion, loosening or other defects,-extrusion, wrinkle, split, missing or other signs of deterioration of the sealing materials.-moisture appears around or behind the curtain wall.CONCLUSIONThe application of curtain wall systems in super-highrise buildings is a big topic. Within the scope of this paper it can only cover a very little of the key issues. Having witnessed the evolution of using curtain wall in Hong Kong for the past 2 to 3 decades, a general trend, as summarized below, can be observed.-Starting from low-cost, local-design and manufactured walling products in the early systems to the imported, deluxe, tailor-designed proprietary systems in recent years.-Starting from simple requirements fulfilling just very basic functional needs of buildings to very specialized products or systems that can meet any stringent requirements as set by designer, engineers or environmental experts.-The old systems were mainly stick systems due to more simple in design and production. Though labour-intensive, the relatively much cheaper labour cost at that time still made it worked acceptably. Contemporary systems are using mainly unit systems that make installation very easy and labour saving, though the design quality and coordination with other building activities are much more demanding.-The old systems that have been used in the first and second generations often inherited with quite a lot of design imperfections and latent defects; while new systems are more reliable, some can be regarded as almost maintenance-free.Traditional external walling methods using applied-onto products such as tile or spray-on coating are still dominating in Hong Kong. However, it is notable that the use of curtain wall is gaining its popularity quite rapidly among designers and developers due to its unreplaceable attractiveness as well as slim and fashionable appearance.Further development and improvement in the use of curtain wall systems is an ongoing process in Hong Kong. The areas of improvement may be aiming at the development of more specific functioned, more reliable and long-life systems. Such targets may be achieved by the use of more advanced glass products, sealing compounds, gaskets or in the development of more sophisticated connecting systems; as well as the introduction of other additional functions that curtain wall may take up like the incorporation of photo-cell onto panels of wall, the providing of automatic/robotic machine in the system for external wall cleansing, or curtain wall capable to perform light show at night. Meanwhile, the continual improvement of workmanship and refinement of work detailing in particular to the areas directly in touch with the building structure or other building finishes, is a prime concern to the ensurance of a good curtain wall system, that sometimes project executives may easily overlooked.中文译文：超高层建筑幕墙系统的结构与性能香港城市大学，建筑科学与技术部Raymond WM Wong引言几十年来超高层建筑的建设在香港一直非常活跃。
