随着我国经济的发展,建筑行业已经朝着多元化方向发展,建筑行业在我国经济发展中起着非常重要的作用。
而建筑工程管理工作直接关系到工程的质量、成本管理、人员的安全、企业的经营效益,甚至关系到企业的生死存亡,但是我国建筑工程管理在现阶段存在许多的不足:管理体制不健全。
我国大部分的建筑工程为了节约人员开支,减少了建筑工程管理机构的人员数量和质量。
管理制度深入性不足。
建筑行业的相关管理制度都是由一些著名的建筑行业专家等共同研究制定的,但是在各建筑单位中就只是一张纸,他们也都只是为了应付上级的检查,并不能应用到建筑工程管理上。
在我国建筑工程管理工作中,难以全面确立我国建筑工程管理思路体系,主要是因为我国缺乏管理理论和经验。
建立建筑工程管理思路体系是专业性较强的问题,其实施必须由资深的建筑学科专家和具有丰富工作经验的管理人员来组织,只有这样才能实现。
国外建筑行业无论是技术还是理论都比较先进,因此我国在建筑工程管理思路体系的建立过程中,必须借鉴国外的先进理念,另外,还必须吸取先进的建筑工程管理方法,并对各方面的资料加以综合和整体。
总之,要想确保我国建筑工程管理工作的有序进行,必须以健全的工程管理思路体系作为建筑工程总体管理水平提升的基本保障。
加强施工质量管理,建立合理可行的质量保证体系,将工程的质量工作落到实处。
工程施工企业要根据质量保证体系,形成行之有效的质量保证系统,树立质量方针,从而让其更加有指令性、系统性及可操作性。
要将人、材料和机械各个要素有效结合起来。
首先,人是质量控制的核心,要把人作为控制的推动力,充分调动人的积极性,树立工程质量第一的观念。
其次,施工材料作为建筑产品的主体,对材料质量的控制是工程质量控制的关键。
最后,工程施工的机械是进行施工机械化的主要标志,对现代化项目施工起到不可缺少的作用,它直接影响了施工项目的进度和质量,所以,选好用好工程机械设备非常重要。
所以,应该根据工程项目的具体特点,综合考虑各种环境因素,实施有效的施工现场控制,为保证施工质量及安全创造良好的外部条件。

The objectives of the model were the minimum cost loss due to the delay of the time limit of the projects and the minimum delay of the project with the highest priority .Then a Genetic Algorithm to solve the model was introduced. Finally, a numerical example was used to testify the feasibility of the model and the algorithm.Index Terms—Genetic Algorithm, Human Resource Allocation, Multi-project’s project’s priority .1.INTRODUCTIONMore and more enterprises are facing the challenge of multi-project management, which has been the focus among researches on project management. In multi-project environment ,the share are competition of resources such as capital , time and human resources often occur .Therefore , it’s critical to schedule projects in order tosatisfy the different resource demands and to shorten the projects’ duration time with resources constrained ,as in [1].For many enterprises ,the human resources are the most precious asset .So enterprises should reasonably and effectively allocateeach resource , especially the human resource ,in order to shorten the time and cost of projects and to increase the benefits .Some literatures have discussed the resource allocation problem in multi-project environment with resources constrained. Reference [1] designed an iterative algorithm and proposed a mathematical model of the resource-constrained multi-project scheduling .Based on work breakdown structure (WBS) and Dantzig-Wolfe decomposition method ,a feasible multi-project planning method was illustrated , as in [2] . References [3,4] discussed the resource-constrained project scheduling based on Branch Delimitation method .Reference [5] put forward the framework of human resource allocation in multi-project in Long-term ,medium-term and short-term as well as research and development(R&D) environment .Based on GPSS language, simulation model of resou rces allocation was built to get the project’s duration time and resources distribution, as in [6]. Reference [7] solved the engineering project’s resources optimization problem using Genetic Algorithms. These literatures reasonably optimized resources allocation in multi-project, but all had the same prerequisite thatthe project’s importance is the same to each other .This paper will analyze the effects of project’s priority on human resource allocation ,which is to be introduced into a mathematical model ;finally ,a Genetic Algorithm is used to solve the model. 2.EFFECTS OF PROJECTS PRIORITY ON HUMAN RESOUCE ALLOCATION AND THEAFFECTING FACTORS OF PROJECT’S PRIORITYResource sharing is one of the main characteristics of multi-project management .The allocation of shared resources relates to the efficiency and rationality of the use of resources .Whenresource conflict occurs ,the resource demand of the project with highest priority should be satisfied first. Only after that, can the projects with lower priority be considered.Based on the idea of project classification management ,this paper classifies the affecting factors of project’s priority into three categories ,as the proj ect’s benefits ,the complexity of project management and technology , and the strategic influence on the enterprise’s future development . The priority weight of the project is the function of the above three categories, as shown in (1).W=f(I,c,s…) (1)Wh ere w refers to project’s priority weight; I refers to the benefits of the project; c refers to the complexity of the project, including the technology and management; s refers to the influenceof the project on enterprise .The bigger the values of the three categories, the higher the priority is.3.HUMAN RESOURCE ALLOCATION MODEL IN MULTI-PROJECT ENVIRONMENT3.1Problem DescriptionAccording to the constraint theory, the enterprise should strictly differentiate the bottleneck resources and the non-bottleneck resources to solve the constraint problem of bottleneck resources .This paper will stress on the limited critical human resources being allocated to multi-project with definite duration times and priority.To simplify the problem, we suppose that that three exist several parallel projects and a shared resources storehouse, and the enterprise’s operation only involves one kind of c ritical human resources. The supply of the critical human resource islimited, which cannot be obtained by hiring or any other ways during a certain period .when resource conflict among parallel projects occurs, we may allocate the human resource to multi-project according to project’s priorities .The allocation of non-critical independent human resources is not considered in this paper, which supposes that the independent resources that each project needs can be satisfied.Engineering projects usually need massive critical skilled humanresources in some critical chain ,which cannot be substituted by the other kind of human resources .When the critical chains of projects at the same time during some period, there occur resource conflict and competition .The paper also supposes that the corresponding network planning of various projects have already been established ,and the peaks of each project’s resources demand have been optimized .The delay of the critical chain will affect the whole project’s duration t ime .3.2 Model HypothesesThe following hypotheses help us to establish a mathematical model:(1)The number of mutually independent projects involved inresource allocation problem in multi-project is N. Eachproject is indicated with Q i ,while i=1,2, … N.(2)The priority weights of multi-project have beendetermined ,which are respectively w 1,w 2…w n .(3)The total number of the critical human resources is R ,withr k standing for each person ,while k=1,2, …,R(4)Δki = others toprojectQ rcer humanresou i k 01(5)Resources capturing by several projects begins on time. tEi isthe expected duration time of project I that needs the critical resources to finish some task after time t ,on the premise that the human resources demand can be satisfied .tAi is the real duration time of project I that needs the critical resource to finish some task after time t .(6)According to the contract ,if the delay of the project happensthe daily cost loss due to the delay is △c i for projectI .According to the projec t’s importance ,the delay of aproject will not only cause the cost loss ,but will also damage the prestige and status of the enterprise .(while the latent cost is difficult to quantify ,it isn’t considered in this article temporarily.)(7)From the hypothesis (5) ,we can know that after time t ,thetime-gap between the real and expected duration time of project I that needs the critical resources to finish some task is △t i,( △t i=t A i-t E i). For there exists resources competition, the time –gap is necessarily a positive number.(8)According to hypotheses (6) and (7), the total cost loss ofproject I is C i (C i= △t i* △C i ).(9)The duration time of activities can be expressed by theworkload of activities divided by the quantity of resources ,which can be indicated with following expression of t A i =ηi/R i*,.In the expression , ηi refers to the workload of projects I during some period ,which is supposed to be fixed and pre-determined by the project managers on project planningphase ; R i * refers to the number of the critical human resourcesbeing allocated to projects I actually, with the equation R i * =∑=R k ki 1δexisting. Due to the resource competition theresource demands of projects with higherPriorities may be guarantee, while those projects with lower priorities may not be fully guaranteed. In this situation, the decrease of the resource supply will lead to the increase of the duration time of activities and the project, while theworkload is fixed.3.3 Optimization ModelBased on the above hypotheses, the resource allocation modelin multi-project environment can be established .Here, the optimization model is :F i =min Z i = min ∑∑==Ni i N i Ci 11ω =min i i N i i N i c t ??∑∑==11ω (2) =min ∑∑==N i i N i 11ω )E i R i ki i t - ??∑=1δη i c ? 2F =min Z 2=min ()i t ?=min )E i R i ki i t -∑=1δη (3)。

IntroductionHospital building projects, are of key importance, and involve significant investment, and usually take a long-term development period. Hospital building projects are also very complex due to the complicated requirements regarding hygiene, safety, special equipments, and handling of a large amount of data. The building process is very dynamic and comprises iterative phases and intermediate changes. Many actors with shifting agendas, roles and responsibilities are actively involved, such as: the healthcare institutions, national and local governments, project developers, financial institutions, architects, contractors, advisors, facility managers, and equipment manufacturers and suppliers. Such building projects are very much influenced, by the healthcare policy, which changes rapidly in response to the medical, societal and technological developments, and varies greatly between countries (World Health Organization, 2000). In The Netherlands, for example, the way a building project in the healthcare sector is organised is undergoing a major reform due to a fundamental change in the Dutch health policy that was introduced in 2008.The rapidly changing context posts a need for a building with flexibility over its lifecycle. In order to incorporate life-cycle considerations in the building design, construction technique, and facility management strategy, a multidisciplinary collaboration is required. Despite the attempt for establishing integrated collaboration, healthcare building projects still facesserious problems in practice, such as: budget overrun, delay, and sub-optimal quality in terms of flexibility, end-user?s dissatisfaction, and energy inefficiency. It is evident that the lack of communication and coordination between the actors involved in the different phases of a building project is among the most important reasons behind these problems. The communication between different stakeholders becomes critical, as each stakeholder possesses different setof skills. As a result, the processes for extraction, interpretation, and communication of complex design information from drawings and documents are often time-consuming and difficult. Advanced visualisation technologies, like 4D planning have tremendous potential to increase the communication efficiency and interpretation ability of the project team members. However, their use as an effective communication tool is still limited and not fully explored. There are also other barriers in the information transfer and integration, for instance: many existing ICT systems do not support the openness of the data and structure that is prerequisite for an effective collaboration between different building actors or disciplines.Building information modelling (BIM) offers an integrated solution to the previously mentioned problems. Therefore, BIM is increasingly used as an ICT support in complex building projects. An effective multidisciplinary collaboration supported by an optimal use of BIM require changing roles of the clients, architects, and contractors; new contractual relationships; and re-organised collaborative processes. Unfortunately, there are still gaps in the practical knowledge on how to manage the building actors to collaborate effectively in their changing roles, and todevelop and utilise BIM as an optimal ICT support of the collaboration.This paper presents a general review of the practical implications of building information modelling (BIM) based on literature review and case studies. In the next sections, based on literature and recent findings from European research project InPro, the framework for integrated collaboration and the use of BIM are analysed. Subsequently, through the observation of two ongoing pilot projects in The Netherlands, the changing roles of clients, architects, and contractors through BIM application are investigated. In conclusion, the critical success factors as well as the main barriers of a successful integrated collaboration using BIM are identified.2. Changing roles through integrated collaboration and life-cycle design approachesA hospital building project involves various actors, roles, and knowledge domains. In The Netherlands, the changing roles of clients, architects, and contractors in hospital building projects are inevitable due the new healthcare policy. Previously under the Healthcare Institutions Act (WTZi), healthcare institutions were required to obtain both a license and a building permit for new construction projects and major renovations. The permit was issued by the Dutch Ministry of Health. The healthcare institutions were then eligible to receive financial support from the government. Since 2008, new legislation on the management of hospital building projects and real estate has come into force. In this new legislation, a permit for hospital building project under the WTZi is no longer obligatory, nor obtainable (Dutch Ministry of Health, Welfare and Sport, 2008). This change allows more freedom from the state-directed policy, and respectively,allocates more responsibilities to the healthcare organisations to deal with the financing and management of their real estate. The new policy implies that the healthcare institutions are fully responsible to man age and finance their building projects and real estate. The government?s support for the costs of healthcare facilities will no longer be given separately, but will be included in the fee for healthcare services. This means that healthcare institutions must earn back their investment on real estate through their services. This new policy intends to stimulate sustainable innovations in the design, procurement and management of healthcare buildings, which will contribute to effective and efficient primary healthcare services.The new strategy for building projects and real estate management endorses an integrated collaboration approach. In order to assure the sustainability during construction, use, and maintenance, the end-users, facility managers, contractors and specialist contractors need to be involved in the planning and design processes. The implications of the new strategy are reflected in the changing roles of the building actors and in the new procurement method.In the traditional procurement method, the design, and its details, are developed by the architect, and design engineers. Then, the client (the healthcare institution) sends an application to the Ministry of Healthto obtain an approval on the building permit and the financial support from the government. Following this, a contractor is selected through a tender process that emphasises the search for the lowest-price bidder. During the construction period, changes often take place due to constructability problems of the design and new requirements from the client.Because of the high level of technical complexity, and moreover, decision-making complexities, the whole process from initiation until delivery of a hospital building project can take up to ten years time. After the delivery, the healthcare institution is fully in charge of the operation of the facilities. Redesigns and changes also take place in the use phase to cope with new functions and developments in the medical world.The integrated procurement pictures a new contractual relationship between the parties involved in a building project. Instead of a relationship between the client and architect for design, and the client and contractor for construction, in an integrated procurement the client only holds a contractual relationship with the main party that is responsible for both design and construction. The traditional borders between tasks and occupational groups become blurred since architects, consulting firms, contractors, subcontractors, and suppliers all stand on the supply side in the building process while the client on the demand side. Such configuration puts the architect, engineer and contractor in a very different position that influences not only their roles, but also their responsibilities, tasks and communication with the client, the users, the team and other stakeholders.The transition from traditional to integrated procurement method requires a shift of mindset of the parties on both the demand and supply sides. It is essential for the client and contractor to have a fair and open collaboration in which both can optimally use their competencies. The effectiveness of integrated collaboration is also determined by the client?s capacity and strategy to organize innovative tendering procedures.A new challenge emerges in case of positioning an architect in a partnership with the contractor instead of with the client. In case of the architect enters a partnership with the contractor, an important issues is how to ensure the realisation of the architectural values as well as innovative engineering through an efficient construction process. In another case, the architect can stand at the client?s side in a strategic advisory role instead of being the designer. In this case, the architect?s responsibility is translating client?s requirements and wishes into the architectural values to be included in the design specification, and evaluating the contractor?s proposal against this. In any of this new role, the architect holds the responsibilities as stakeholder interest facilitator, custodian of customer value and custodian of design models.The transition from traditional to integrated procurement method also brings consequences in the payment schemes. In the traditional building process, the honorarium for the architect is usually based on a percentage of the project costs; this may simply mean that the more expensive the building is, the higher the honorarium will be. The engineer receives the honorarium based on the complexity of the design and the intensity of the assignment. A highly complex building, which takes a number of redesigns, is usually favourable for the engineers in terms of honorarium. A traditional contractor usually receives the commission based on the tender to construct the building at the lowest price by meeting the minimum specifications given by the client. Extra work due to modifications is charged separately to the client. After the delivery, the contractor is no longer responsible for the long-term use of the building. In the traditional procurement method, all risks are placed with theclient.In integrated procurement method, the payment is based on the achieved building performance; thus, the payment is non-adversarial. Since the architect, engineer and contractor have a wider responsibility on the quality of the design and the building, the payment is linked to a measurement system of the functional and technical performance of the building over a certain period of time. The honorarium becomes an incentive to achieve the optimal quality. If the building actors succeed to deliver a higher added-value thatexceed the minimum client?s requirements, they will receive a bonus in accordance to the client?s extra gain. The level of transparency is also improved. Open book accounting is an excellent instrument provided that the stakeholders agree on the information to be shared and to its level of detail (InPro, 2009).Next to the adoption of integrated procurement method, the new real estate strategy for hospital building projects addresses an innovative product development and life-cycle design approaches. A sustainable business case for the investment and exploitation of hospital buildings relies on dynamic life-cycle management that includes considerations and analysis of the market development over time next to the building life-cycle costs (investment/initial cost, operational cost, and logistic cost). Compared to the conventional life-cycle costing method, the dynamic life-cycle management encompasses a shift from focusing only on minimizing the costs to focusing on maximizing the total benefit that can be gained. One of the determining factors for a successful implementation of dynamic life-cycle management is the sustainable design of the building and building components, which means that the design carriessufficient flexibility to accommodate possible changes in the long term (Prins, 1992).Designing based on the principles of life-cycle management affects the role of the architect, as he needs to be well informed about the usage scenarios and related financial arrangements, the changing social and physical environments, and new technologies. Design needs to integrate people activities and business strategies over time. In this context, the architect is required to align the design strategies with the organisational, local and global policies on finance, business operations, health and safety, environment, etc.The combination of process and product innovation, and the changing roles of the building actors can be accommodated by integrated project delivery or IPD (AIA California Council, 2007). IPD is an approach that integrates people, systems, business structures and practices into a process that collaboratively harnesses the talents and insights of all participants to reduce waste and optimize efficiency through all phases of design, fabrication and construction. IPD principles can be applied to a variety of contractual arrangements. IPD teams will usually include members well beyond the basic triad of client, architect, and contractor. At a minimum, though, an Integrated Project should include a tight collaboration between the client, the architect, and the main contractor ultimately responsible for construction of the project, from the early design until the project handover. The key to a successful IPD is assembling a team that is committed to collaborative processes and is capable of working together effectively. IPD is built on collaboration. As a result, it can only be successful if the participants share and apply common values and goals.3. Changing roles through BIM applicationBuilding information model (BIM) comprises ICT frameworks and tools that can support the integrated collaboration based on life-cycle design approach. BIM is a digital representation of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its lifecycle from inception onward (National Institute of Building Sciences NIBS, 2007). BIM facilitates time and place independent collaborative working. A basic premise of BIM is collaboration by different stakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM to support and reflect the roles of that stakeholder. BIM in its ultimate form, as a shared digital representation founded on open standards for interoperability, can become a virtual information model to be handed from the design team to the contractor and subcontractors and then to the client.BIM is not the same as the earlier known computer aided design (CAD). BIM goes further than an application to generate digital (2D or 3D) drawings. BIM is an integrated model in which all process and product information is combined, stored, elaborated, and interactively distributed to all relevant building actors. As a central model for all involved actors throughout the project lifecycle, BIM develops andevolves as the project progresses. Using BIM, the proposed design and engineering solutions can be measured against the client?s requirements and expected building performance. The functionalities of BIM to support the design process extend to multidimensional (nD), including: three-dimensional visualisation and detailing, clash detection, material schedule, planning, costestimate, production and logistic information, and as-built documents. During the construction process, BIM can support the communication between the building site, the factory and the design office– which is crucial for an effective and efficient prefabrication and assembly processes as well as to prevent or solve problems related to unforeseen errors or modifications. When the building is in use, BIM can be used in combination with the intelligent building systems to provide and maintain up-to-date information of the building performance, including the life-cycle cost.To unleash the full potential of more efficient information exchange in the AEC/FM industry in collaborative working using BIM, both high quality open international standards and high quality implementations of these standards must be in place. The IFC open standard is generally agreed to be of high quality and is widely implemented in software. Unfortunately, the certification process allows poor quality implementations to be certified and essentially renders the certified software useless for any practical usage with IFC. IFC compliant BIM is actually used less than manual drafting for architects and contractors, and show about the same usage for engineers. A recent survey shows that CAD (as a closed-system) is still the major form of technique used in design work (over 60 per cent) while BIM is used in around 20 percent of projects for architects and in around 10 per cent of projects for engineers and contractors.The application of BIM to support an optimal cross-disciplinary and cross-phase collaboration opens a new dimension in the roles and relationships between the building actors. Several most relevant issues are: the new role of a model manager; the agreement on the access right and IntellectualProperty Right (IPR); the liability and payment arrangement according to the type of contract and in relation to the integrated procurement; and the use of open international standards.Collaborative working using BIM demands a new expert role of a model manager who possesses ICT as well as construction process know-how (InPro, 2009). The model manager deals with the system as well as with the actors. He provides and maintains technological solutions required for BIM functionalities, manages the information flow, and improves the ICT skills of the stakeholders. The model manager does not take decisions on design and engineering solutions, nor the organisational processes, but his roles in the chain of decision making are focused on:the development of BIM, the definition of the structure and detail level of the model, and the deployment of relevant BIM tools, such as for models checking, merging, and clash detections;the contribution to collaboration methods, especially decision making and communication protocols, task planning, and risk management;and the management of information, in terms of data flow and storage, identification of communication errors, and decision or process (re-)tracking.Regarding the legal and organisational issues, one of the actual questions is: “In what way does the intellectual property right (IPR) in collaborative working using BIM differ from the IPR in a traditional teamwork?”. In terms of combine d work, the IPR of each element is at tached to its creator. Although it seems to be a fully integrated design, BIM actually resulted from a combination of works/elements; for instance: the outline of the building design, is created by the architect, the design for theelectrical system, is created by the electrical contractor, etc. Thus, in case of BIM as a combined work, the IPR is similar to traditional teamwork. Working with BIM with authorship registration functionalities may actually make it easier to keep track of the IPR.How does collaborative working, using BIM, effect the contractual relationship? On the one hand,collaborative working using BIM does not necessarily change the liability position in the contract nor does it obligate an alliance contract. The General Principles of BIM A ddendum confirms: …This does not effectuate or require a restructuring of contractual relationships or shifting of risks between or among the Project Participants other than as specifically required per the Protocol Addendum and its Attachments? (ConsensusDOCS, 2008). On the other hand, changes in terms of payment schemes can be anticipated. Collaborative processes using BIM will lead to the shifting of activities from to the early design phase. Much, if not all, activities in the detailed engineering and specification phase will be done in the earlier phases. It means that significant payment for the engineering phase, which may count up to 40 per cent of the design cost, can no longer be expected. As engineering work is done concurrently with the design, a new proportion of the payment in the early design phase is necessary.4. Review of ongoing hospital building projects using BIMIn The Netherlands, the changing roles in hospital building projects are part of the strategy, which aims at achieving a sustainable real estate in response to the changing healthcare policy. Referring to literature and previous research, the main factors that influence the success of the changing roles can be concluded as: the implementation of an integrated procurementmethod and a life-cycle design approach for a sustainable collaborative process; the agreement on the BIM structure and the intellectual rights; and the integration of the role of a model manager. The preceding sections have discussed the conceptual thinking on how to deal with these factors effectively. This current section observes two actual projects and compares the actual practice with the conceptual view respectively.The main issues, which are observed in the case studies, are: the selected procurement method and the roles of the involved parties within this method;the implementation of the life-cycle design approach;the type, structure, and functionalities of BIM used in the project;the openness in data sharing and transfer of the model, and the intended use of BIM in the future; and the roles and tasks of the model manager.The pilot experience of hospital building projects using BIM in the Netherlands can be observed at University Medical Centre St Radboud (further referred as UMC) and Maxima Medical Centre (further referred as MMC). At UMC, the new building project for the Faculty of Dentistry in the city of Nijmegen has been dedicated as a BIM pilot project. At MMC, BIM is used in designing new buildings for Medical Simulation and Mother-and-Child Centre in the city of Veldhoven.The first case is a project at the University Medical Centre (UMC) St Radboud. UMC is more than just a hospital. UMC combines medical services, education and research. More than 8500 staff and 3000 students work at UMC. As a part of the innovative real estate strategy, UMC has considered to use BIM for its building projects. The new development of the Faculty ofDentistry and the surrounding buildings on the Kapittelweg in Nijmegen has been chosen as a pilot project to gather practical knowledge and experience on collaborative processes with BIM support.The main ambition to be achieved through the use of BIM in the building projects at UMC can be summarised as follows: using 3D visualisation to enhance the coordination and communication among the building actors, and the user participation in design;integrating the architectural design with structural analysis, energy analysis, cost estimation, and planning;interactively evaluating the design solutions against the programme of requirements and specifications;reducing redesign/remake costs through clash detection during the design process; andoptimising the management of the facility through the registration of medical installations andequipments, fixed and flexible furniture, product and output specifications, and operational data.The second case is a project at the Maxima Medical Centre (MMC). MMC is a large hospital resulted from a merger between the Diaconessenhuis in Eindhoven and St Joseph Hospital in Veldhoven. Annually the 3,400 staff of MMC provides medical services to more than 450,000 visitors and patients. A large-scaled extension project of the hospital in Veldhoven is a part of its real estate strategy. A medical simulation centre and a women-and-children medical centre are among the most important new facilities within this extension project. The design has been developed using 3D modelling with several functionalities of BIM.The findings from both cases and the analysis are as follows.Both UMC and MMC opted for a traditional procurement method in which the client directly contracted an architect, a structural engineer, and a mechanical, electrical and plumbing (MEP) consultant in the design team. Once the design and detailed specifications are finished, a tender procedure will follow to select a contractor. Despite the choice for this traditional method, many attempts have been made for a closer and more effective multidisciplinary collaboration. UMC dedicated a relatively long preparation phase with the architect, structural engineer and MEP consultant before the design commenced. This preparation phase was aimed at creating a common vision on the optimal way for collaboration using BIM as an ICT support. Some results of this preparation phase are: a document that defines the common ambition for the project and the collaborative working process and a semi-formal agreement that states the commitment of the building actors for collaboration. Other than UMC, MMC selected an architecture firm with an in-house engineering department. Thus, the collaboration between the architect and structural engineer can take place within the same firm using the same software application.Regarding the life-cycle design approach, the main attention is given on life-cycle costs, maintenance needs, and facility management. Using BIM, both hospitals intend to get a much better insight in these aspects over the life-cycle period. The life-cycle sustainability criteria are included in the assignments for the design teams. Multidisciplinary designers and engineers are asked to collaborate more closely and to interact with the end-users to address life-cycle requirements. However, ensuring the building actors to engage in an integrated collaboration to generate sustainable design solutions that meet the life-cycle。

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 consideration s .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 of his 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 toapproximate 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 emphasis will 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 specific form 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.1.Reinforced ConcretePlain concrete is formed from a hardened mixture of cement ,water ,fine aggregate, coarse aggregate (crushed stone or gravel),air, and often other admixtures. The plastic mix is placed and consolidated in the formwork, then cured to facilitate the acceleration of the chemical hydration reaction lf the cement/water mix, resulting in hardened concrete. The finished product has high compressive strength, and low resistance to tension, such that its tensile strength is approximately one tenth lf its compressive strength. Consequently, tensile and shear reinforcement in the tensile regions of sections has to be provided to compensate for the weak tension regions in the reinforced concrete element.It is this deviation in the composition of a reinforces concrete section from the homogeneity of standard wood or steel sections that requires a modified approach to the basic principles of structural design. The two components of the heterogeneous reinforced concrete section are to be so arranged and proportioned that optimal use is made of the materials involved. This is possible because concrete can easily be given any desired shape by placing and compacting the wet mixture of the constituent ingredients are properly proportioned, the finished product becomes strong, durable, and, in combination with the reinforcing bars, adaptable for use as main members of any structural system.The techniques necessary for placing concrete depend on the type of member to be cast: that is, whether it is a column, a bean, a wall, a slab, a foundation. a mass columns, or an extension of previously placed and hardened concrete. For beams, columns, and walls, the forms should be well oiled after cleaning them, and the reinforcement should be cleared of rust and other harmful materials. In foundations, the earth should be compacted and thoroughly moistened to about 6 in. in depth to avoid absorption of the moisture present in the wet concrete. Concrete should always be placed in horizontal layers which are compacted by means of high frequency power-driven vibrators of either the immersion or external type, as the case requires, unless it is placed by pumping. It must be kept in mind, however, that over vibration can be harmful since it could cause segregation of the aggregate and bleeding of the concrete.Hydration of the cement takes place in the presence of moisture at temperatures above 50°F. It is necessary to maintain such a condition in order that the chemical hydration reaction can take place. If drying is too rapid, surface cracking takes place. This would result in reduction of concrete strength due to cracking as well as the failure to attain full chemical hydration.It is clear that a large number of parameters have to be dealt with in proportioning a reinforced concrete element, such as geometrical width, depth, area of reinforcement, steel strain, concrete strain, steel stress, and so on. Consequently, trial and adjustment is necessary in the choice ofconcrete sections, with assumptions based on conditions at site, availability of the constituent materials, particular demands of the owners, architectural and headroom requirements, the applicable codes, and environmental reinforced concrete is often a site-constructed composite, in contrast to the standard mill-fabricated beam and column sections in steel structures.A trial section has to be chosen for each critical location in a structural system. The trial section has to be analyzed to determine if its nominal resisting strength is adequate to carry the applied factored load. Since more than one trial is often necessary to arrive at the required section, the first design input step generates into a series of trial-and-adjustment analyses.The trial-and –adjustment procedures for the choice of a concrete section lead to the convergence of analysis and design. Hence every design is an analysis once a trial section is chosen. The availability of handbooks, charts, and personal computers and programs supports this approach as a more efficient, compact, and speedy instructional method compared with the traditional approach of treating the analysis of reinforced concrete separately from pure design.2. EarthworkBecause earthmoving methods and costs change more quickly than those in any other branch of civil engineering, this is a field where there are real opportunities for the enthusiast. In 1935 most of the methods now in use for carrying and excavating earth with rubber-tyred equipment did not exist. Most earth was moved by narrow rail track, now relatively rare, and the main methods of excavation, with face shovel, backacter, or dragline or grab, though they are still widely used are only a few of the many current methods. To keep his knowledge of earthmoving equipment up to date an engineer must therefore spend tine studying modern machines. Generally the only reliable up-to-date information on excavators, loaders and transport is obtainable from the makers.Earthworks or earthmoving means cutting into ground where its surface is too high ( cuts ), and dumping the earth in other places where the surface is too low ( fills). Toreduce earthwork costs, the volume of the fills should be equal to the volume of the cuts and wherever possible the cuts should be placednear to fills of equal volume so as to reduce transport and double handlingof the fill. This work of earthwork design falls on the engineer who lays out the road since it is the layout of the earthwork more than anything else which decides its cheapness. From the available maps ahd levels, the engineering must try to reach as many decisions as possible in the drawing office by drawing cross sections of the earthwork. On the site when further information becomes available he can make changes in jis sections and layout,but the drawing lffice work will not have been lost. It will have helped him to reach the best solution in the shortest time.The cheapest way of moving earth is to take it directly out of the cut and drop it as fill with the same machine. This is not always possible, but when it canbe done it is ideal, being both quick and cheap. Draglines, bulldozers and face shovels an do this. The largest radius is obtained with thedragline,and the largest tonnage of earth is moved by the bulldozer, though only over short distances.The disadvantages of the dragline are that it must dig below itself, it cannot dig with force into compacted material, it cannot dig on steep slopws, and its dumping and digging are not accurate.Face shovels are between bulldozers and draglines, having a larger radius of action than bulldozers but less than draglines. They are anle to dig into a vertical cliff face in a way which would be dangerous tor a bulldozer operator and impossible for a dragline. Each piece of equipment should be level of their tracks and for deep digs in compact material a backacter is most useful, but its dumping radius is considerably less than that of the same escavator fitted with a face shovel.Rubber-tyred bowl scrapers are indispensable for fairly level digging where the distance of transport is too much tor a dragline or face shovel. They can dig the material deeply ( but only below themselves ) to a fairly flat surface, carry it hundreds of meters if need be, then drop it and level it roughly during the dumping. For hard digging it is often found economical to keep a pusher tractor ( wheeled or tracked ) on the digging site, to push each scraper as it returns to dig. As soon as the scraper is full,the pusher tractor returns to the beginning of the dig to heop to help the nest scraper.Bowl scrapers are often extremely powerful machines;many makers build scrapers of 8 cubic meters struck capacity, which carry 10 m ³ heaped. The largest self-propelled scrapers are of 19 m ³struck capacity ( 25 m ³ heaped )and they are driven by a tractor engine of 430 horse-powers.Dumpers are probably the commonest rubber-tyred transport since they can also conveniently be used for carrying concrete or other building materials. Dumpers have the earth container over the front axle on large rubber-tyred wheels, and the container tips forwards on most types, though in articulated dumpers the direction of tip can be widely varied. The smallest dumpers have a capacity of about 0.5 m ³, and the largest standard types are of about 4.5 m ³. Special types include the self-loading dumper of up to 4 m ³ and the articulated type of about 0.5 m ³. The distinction between dumpers and dump trucks must be remembered .dumpers tip forwards and the driver sits behind the load. Dump trucks are heavy, strengthened tipping lorries, the driver travels in front lf the load and the load is dumped behind him, so they are sometimes called rear-dump trucks.3.Safety of StructuresThe principal scope of specifications is to provide general principles and computational methods in order to verify safety of structures. The “ safety factor ”, which according to modern trends is independent of the nature and combination of the materials used, can usually be defined as the ratio between the conditions. This ratio is also proportional to the inverse of the probability ( risk ) of failure of the structure.Failure has to be considered not only as overall collapse of the structure but also asunserviceability or, according to a more precise. Common definition. As the reaching of a “ limit state ” which causes the construction not to accomplish the task it was designed for. Ther e are two categories of limit state :(1)Ultimate limit sate, which corresponds to the highest value of the load-bearing capacity. Examples include local buckling or global instability of the structure; failure of some sections and subsequent transformation of the structure into a mechanism; failure by fatigue; elastic or plastic deformation or creep that cause a substantial change of the geometry of the structure; and sensitivity of the structure to alternating loads, to fire and to explosions.(2)Service limit states, which are functions of the use and durability of the structure. Examples include excessive deformations and displacements without instability; early or excessive cracks; large vibrations; and corrosion.Computational methods used to verify structures with respect to the different safety conditions can be separated into:(1)Deterministic methods, in which the main parameters are considered as nonrandom parameters.(2)Probabilistic methods, in which the main parameters are considered as random parameters.Alternatively, with respect to the different use of factors of safety, computational methods can be separated into:(1)Allowable stress method, in which the stresses computed under maximum loads are compared with the strength of the material reduced by given safety factors.(2)Limit states method, in which the structure may be proportioned on the basis of its maximum strength. This strength, as determined by rational analysis, shall not be less than that required to support a factored load equal to the sum of the factored live load and dead load ( ultimate state ).The stresses corresponding to working ( service ) conditions with unfactored live and dead loads are compared with prescribed values ( service limit state ) . From the four possible combinations of the first two and second two methods, we can obtain some useful computational methods. Generally, two combinations prevail:(1)deterministic methods, which make use of allowable stresses.(2)Probabilistic methods, which make use of limit states.The main advantage of probabilistic approaches is that, at least in theory, it is possible to scientifically take into account all random factors of safety, which are then combined to define the safety factor. probabilistic approaches depend upon :(1) Random distribution of strength of materials with respect to the conditions of fabrication and erection ( scatter of the values of mechanical properties through out the structure );(2) Uncertainty of the geometry of the cross-section sand of the structure ( faults andimperfections due to fabrication and erection of the structure );(3) Uncertainty of the predicted live loads and dead loads acting on the structure;(4)Uncertainty related to the approximation of the computational method used ( deviation of the actual stresses from computed stresses ).Furthermore, probabilistic theories mean that the allowable risk can be based on several factors, such as :(1) Importance of the construction and gravity of the damage by its failure;(2)Number of human lives which can be threatened by this failure;(3)Possibility and/or likelihood of repairing the structure;(4) Predicted life of the structure.All these factors are related to economic and social considerations such as：(1) Initial cost of the construction;(2) Amortization funds for the duration of the construction;(3) Cost of physical and material damage due to the failure of the construction;(4) Adverse impact on society;(5) Moral and psychological views.The definition of all these parameters, for a given safety factor, allows construction at the optimum cost. However, the difficulty of carrying out a complete probabilistic analysis has to be taken into account. For such an analysis the laws of the distribution of the live load and its induced stresses, of the scatter of mechanical properties of materials, and of the geometry of the cross-sections and the structure have to be known. Furthermore, it is difficult to interpret the interaction between the law of distribution of strength and that of stresses because both depend upon the nature of the material, on the cross-sections and upon the load acting on the structure. These practical difficulties can be overcome in two ways. The first is to apply different safety factors to the material and to the loads, without necessarily adopting the probabilistic criterion. The second is an approximate probabilistic method which introduces some simplifying assumptions ( semi-probabilistic methods ) .文献翻译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。

by various factories or industrial production while civil buildings are those that are used by people for dwelling, employment ,education and other social activities .Key words: industrial buildings; civil buildings; social activitiesA building is closely bound up with people，for it provides with the necessary space to work and live in .As classified by their use ,buildings are mainly of two types :industrial buildings and civil buildings .industrial buildings are used by various factories or industrial production while civil buildings are those that are used by people for dwelling ,employment ,education and other social activities .Industrial buildings are factory buildings that are available for processing and manufacturing of various kinds ,in such fields as the mining industry ,themetallurgical industry ,machine building ,the chemical industry and the textile industry . factory buildings can be classified into two types single-story ones and multi-story ones .the construction of industrial buildings is the same as that of civil buildings .however ,industrial and civil buildings differ in the materials used and in the way they are used .Civil buildings are divided into two broad categories: residential buildings and public buildings .residential buildings should suit family life .each flat should consist of at least three necessary rooms : a living room ,a kitchen and a toilet .public buildings can be used in politics ,cultural activities ,administration work and other services,suchasschools,officebuildings,parks ,hospitals ,shops ,stations ,theatres ,gym nasiums ,hotels ,exhibition halls ,bath pools ,and so on .all of them have different functions ,which in turn require different design types as well.Housing is the living quarters for human beings .the basic function of housing is to provide shelter from the elements ,but people today require much more that of their housing .a family moving into a new neighborhood will to know if the available housing meets its standards of safety ,health ,and comfort .a family will also ask how near the housing is to grain shops ,food markets ,schools ,stores ,the library ,a movie theater ,and the community center .In the mid-1960’s a most important value in housing was sufficient space both inside and out .a majority of families preferred single-family homes on about half an acre of land ,which would provide space for spare-time activities .in highly industrialized countries ,many families preferred to live as far out as possible from the center of a metropolitan area ,even if the wage earners had to travel some distance to their work .quite a large number of families preferred country housing to suburban housing because their chief aim was to get far away from noise ,crowding ,and confusion .the accessibility of public transportation had ceased to be a decisive factor in housing because most workers drove their cars to work .people we’re chiefly interested in the arrangement and size of rooms and the number of bedrooms .Before any of the building can begin ,plans have to be drawn to show what the building will be like ,the exact place in which it is to go and how everything is to be done.An important point in building design is the layout of rooms ,which should provide the greatest possible convenience in relation to the purposes for which they are intended .in a dwelling house ,the layout may be considered under three categories : “day”, “night” ,and “services” .attention must be paid to the provision of easy communication between these areas .the “day”rooms generally include a dining-room ,sitting-room and kitchen ,but other rooms ,such as a study ,may be added ,and there may be a hall .the living-room ,which is generally the largest ,often serves as a dining-room ,too ,or the kitchen may have a d ining alcove .the “night” rooms consist the roost.t he “services” comprise the kitchen ,bathrooms ,larder ,and water-closets .the kitchen and larder connect the services with the day rooms .It is also essential to consider the question of outlook from the various rooms ,and those most in use should preferably face south as possible .it is ,however ,often very difficult to meet the optimum requirements ,both on account of the surroundings and the location of the roads .in resolving these complex problems ,it is also necessary to follow the local town-planning regulations which are concerned with public amenities ,density of population ,height of buildings ,proportion of green space to dwellings ,building lines ,the general appearance of new properties in relation to the neighbourhood ,and so on .There is little standardization in industrial buildings although such buildings still need to comply with local town-planning regulations .the modern trend is towards light ,airy factory buildings .generally of reinforced concrete or metal construction ,a factory can be given a “shed ”type ridge roof ,incorporating windows facing north so as to give evenly distributed natural lighting without sun-glare .Architectural design development so far, is no longer content merely to live and businesses use natural resources are becoming scarce in today's society, energy saving, environmentally friendly building construction to become the development trend of the future. Market has been as energy conservation, green building the driving force,the recent century represented a harmonious environment, real estate sellingenergy-saving also proves this point. This also means that ordinary people had alienated the energy saving type of real estate, gradually unfold the mystery, to the public.Water reuse and efficient use of water resources technologyReflections Harmony century urban life, the introduction of green, energy-saving building construction concept, the full use of geographical terrain and climate, natural advantages, according to human comfort requirements and weather conditions for construction planning and design, Kunming bring a “non-green , uncooperative”, the life of the proposal, environmental protection into a harmonious way of life.Deep sense of crisis of water scarcity, water conservation harmony century by water reuse treatment systems. “Water”, also known as “recycled water” or “back water”, water reuse is the main form of eff icient use of water resources. “Harmony Century” water reuse treatment systems throughout the real estate sub-quality implementation of all water emissions, returning after a biological focus, depth filtration UV disinfection treatment process, used for toilet flushing, car washing, cleaning, and to meet the landscape and a huge pool green eco-system needs, efficient use of water resources, water cost savings of more households.Impermeable layer of drainage technique with noise“Harmony Century” the introduction of the same layer emission technologies, to achieve the same floor of the main drainage branch pipe and branch pipes are not across the floor drain in the floor within the same established connection to the main drainage pipe.The traditional approach, there are a number of drainage construction, it is hard to solve the problem: noise can interfere with the drainage upstairs downstairs; floor are many holes, the downstairs when the fire could spread to the upstairs; maintenance, when renovation of damage to the downstairs ceilings; sewage poured into the trap as a result of health problems; leaks, clogged affect the downstairs tenants, disputes.“Harmony Century” using the same drainage system, installed only in the civil riser, interior designers can be free of the bathroom layout, drainage branch pipe inthe renovation by interior design drawings for installation. As a result, not only solved the problem of traditional drainage patterns to achieve the clarity of property rights, each household has a fully independent health space, tenants will not be the upper interference, while still meeting the personalized decoration, personalized decoration . Solar energy saving lamp“Harmony Century” will be back in two years ago, solar lighting in the planning, is the first application of solar lighting in Kunming than real estate, energy-saving environmental protection played a role model.Solar energy street lights, without power because of their influence, without ditching embedding, not consumption of conventional energy, as long as the sunny spot to be installed and so on. Harmony century, the first to use solar lights, charging at night during the day, no external power supply, safety and energy conservation pollution; the process of charging and switching lights from the microcomputer intelligent control, automatic lights dark, dawn, turn off the lights automatically, without manual operation, stable and reliable , long life, full of energy saving; solar power supply systems over ad hoc charge, discharge, anti-reverse and lightning, etc., more secure and reliable operation.Thermal insulation of aerated concrete brick insulation, noise, radiation Aerated concrete is a new type of light porous materials, it is light weight, good insulation properties, high strength, shock resistance, sound insulation performance, high temperature and so on.Since only the weight of aerated concrete brick and sand-lime brick is equivalent to 1 / 3 of ordinary concrete, 1 / 5, greatly reducing the weight of body building, built to improve the seismic performance of buildings.We can see from the structure, the internal structure of aerated concrete, like bread, like a large number of evenly distributed closed pores, so in general do not have the sound-absorbing building materials performance。

The principle is that the larger size but the thickness must be smaller geometric features should be presented to the plate, the force is close to cylindrical. The wall shear wall structure is a flat component. Its exposure to the force along the plane level of the role of shear and moment, must also take into account the vertical pressure. Operate under the combined action of bending moments and axial force and shear force by the cantilever deep beam under the action of the force level to look into the bottom mounted on the basis of. Shear wall is divided into a whole wall and the associated shear wall in the actual project, a whole wall for example, such as general housing construction in the gable or fish bone structure film walls and small openings wall. Coupled Shear walls are connected by the coupling beam shear wall. But because thegeneral coupling beam stiffness is less than the wall stiffness of the limbs, so. Wall limb alone is obvious. The central beam of the inflection point to pay attention to the wall pressure than the limits of the limb axis. Will form a short wide beams, wide column wall limb shear wall openings too large component at both ends with just the domain of variable cross-section rod in the internal forces under the action of many Wall limb inflection point Therefore, the calculations and construction shouldAccording to approximate the frame structure to consider. The design of shear walls should be based on the characteristics of a variety of wall itself, and different mechanical characteristics and requirements, wall of the internal force distribution and failure modes of specific and comprehensive consideration of the design reinforcement and structural measures. Frame shear wall structure design is to consider the structure of the overall analysis for both directions of the horizontal and vertical effects. Obtain the internal force is required in accordance with the bias or partial pull normal section force calculation. The wall structure of the frame shear wall structural design of the content frame high-rise buildings, in the actual project in the use of the most seismic walls have sufficient quantities to meet the limits of the layer displacement, the location is relatively flexible. Seismic wall for continuous layout, full-length through. Should be designed to avoid the wall mutations in limb length and alignment is not up and down the hole. The same time. The inside of thehole margins column should not be less than 300mm in order to guarantee the length of the column as the edge of the component and constraint edge components. The bi-directional lateral force resisting structural form of vertical and horizontal wall connected. Each other as the affinity of the shear wall. For one, two seismic frame shear walls, even beam high ratio should not greater than 5 and a height of not less than 400mm. Midline column and beams, wall midline should not be greater than the column width of 1/4, in order to reduce the torsional effect of the seismic action on the column. Otherwise can be taken to strengthen the stirrup ratio in the column to make up. If the shear wall shear span than the big two. Even the beam cross-height ratio greater than 2.5, then the design pressure of the cut should not make a big 0.2. However, if the shear wall shear span ratio of less than two coupling beams span of less than 2.5, then the shear compression ratio is not greater than 0.15. The other hand, the bottom of the frame shear wall structure to enhance the design should not be less than 200mm and not less than storey 1/16, other parts should not be less than 160mm and not less than storey 1/20. Around the wall of the frame shear wall structure should be set to the beam or dark beam and the side column to form a border. Horizontal distribution of shear walls can from the shear effect, this design when building higher longer or frame structure reinforcement should be appropriately increased, especially in the sensitive parts of the beam position or temperature,stiffness change is best appropriately increased, then consideration should be given to the wall vertical reinforcement, because it is mainly from the bending effect, and take in some multi-storey shear wall structure reinforced reinforcement rate - like less constrained edge of the component or components reinforcement of the edge component.

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

While the style was conceived early in the 20th century and heavily promoted by a few architects, architectural educators and exhibits, very few Modern buildings were built in the first half of the century. For three decades after the Second World War, however, it became the dominant architectural style for institutional and corporate building.1. OriginsSome historians see the evolution of Modern architecture as a social matter, closely tied to the project of Modernity and hence to the Enlightenment, a result of social and political revolutions.Others see Modern architecture as primarily driven by technological and engineering developments, and it is true that the availability of new building materials such as iron, steel, concrete and glass drove the invention of new building techniques as part of the Industrial Revolution. In 1796, Shrewsbury mill owner Charles Bage first used his "fireproof design, which relied on cast iron and brick with flag stone floors. Such construction greatly strengthened the structure of mills, which enabled them to accommodate much bigger machines. Due to poor knowledge of iron's properties as a construction material, a number of early mills collapsed. It was not until the early 1830s that Eaton Hodgkinson introduced the section beam, leading to widespread use of iron construction, this kind of austere industrial architecture utterly transformed the landscape of northern Britain, leading to the description, πDark satanic millsπof places like Manchester and parts of West Yorkshire. The Crystal Palace by Joseph Paxton at the Great Exhibition of 1851 was an early example of iron and glass construction; possibly the best example is the development of the tall steel skyscraper in Chicago around 1890 by William Le Baron Jenney and Louis Sullivan∙ Early structures to employ concrete as the chief means of architectural expression (rather than for purely utilitarian structure) include Frank Lloyd Wright,s Unity Temple, built in 1906 near Chicago, and Rudolf Steiner,s Second Goetheanum, built from1926 near Basel, Switzerland.Other historians regard Modernism as a matter of taste, a reaction against eclecticism and the lavish stylistic excesses of Victorian Era and Edwardian Art Nouveau.Whatever the cause, around 1900 a number of architects around the world began developing new architectural solutions to integrate traditional precedents (Gothic, for instance) with new technological possibilities- The work of Louis Sullivan and Frank Lloyd Wright in Chicago, Victor Horta in Brussels, Antoni Gaudi in Barcelona, Otto Wagner in Vienna and Charles Rennie Mackintosh in Glasgow, among many others, can be seen as a common struggle between old and new.2. Modernism as Dominant StyleBy the 1920s the most important figures in Modern architecture had established their reputations. The big three are commonly recognized as Le Corbusier in France, and Ludwig Mies van der Rohe and Walter Gropius in Germany. Mies van der Rohe and Gropius were both directors of the Bauhaus, one of a number of European schools and associations concerned with reconciling craft tradition and industrial technology.Frank Lloyd Wright r s career parallels and influences the work of the European modernists, particularly via the Wasmuth Portfolio, but he refused to be categorized with them. Wright was a major influence on both Gropius and van der Rohe, however, as well as on the whole of organic architecture.In 1932 came the important MOMA exhibition, the International Exhibition of Modem Architecture, curated by Philip Johnson. Johnson and collaborator Henry-Russell Hitchcock drew together many distinct threads and trends, identified them as stylistically similar and having a common purpose, and consolidated them into the International Style.This was an important turning point. With World War II the important figures of the Bauhaus fled to the United States, to Chicago, to the Harvard Graduate School of Design, and to Black Mountain College. While Modern architectural design never became a dominant style in single-dwelling residential buildings, in institutional and commercial architecture Modernism became the pre-eminent, and in the schools (for leaders of the profession) the only acceptable, design solution from about 1932 to about 1984.Architects who worked in the international style wanted to break with architectural tradition and design simple, unornamented buildings. The most commonly used materials are glass for the facade, steel for exterior support, and concrete for the floors and interior supports; floor plans were functional and logical. The style became most evident in the design of skyscrapers. Perhaps its most famous manifestations include the United Nations headquarters (Le Corbusier, Oscar Niemeyer, Sir Howard Robertson), the Seagram Building (Ludwig Mies van der Rohe), and Lever House (Skidmore, Owings, and Merrill), all in New York. A prominent residential example is the Lovell House (Richard Neutra) in Los Angeles.Detractors of the international style claim that its stark, uncompromisingly rectangular geometry is dehumanising. Le Corbusier once described buildings as πmachines for living,∖but people are not machines and it was suggested that they do not want to live in machines- Even Philip Johnson admitted he was πbored with the box∕,Since the early 1980s many architects have deliberately sought to move away from rectilinear designs, towards more eclectic styles. During the middle of the century, some architects began experimenting in organic forms that they felt were more human and accessible. Mid-century modernism, or organic modernism, was very popular, due to its democratic and playful nature. Alvar Aalto and Eero Saarinen were two of the most prolific architects and designers in this movement, which has influenced contemporary modernism.Although there is debate as to when and why the decline of the modern movement occurred, criticism of Modern architecture began in the 1960s on the grounds that it was universal, sterile, elitist and lacked meaning. Its approach had become ossified in a πstyleπthat threatened to degenerate into a set of mannerisms. Siegfried Giedion in the 1961 introduction to his evolving text, Space, Time and Architecture (first written in 1941), could begin ,,At the moment a certain confusion exists in contemporary architecture, as in painting; a kind of pause, even a kind of exhaustion/1At the Metropolitan Museum of Art, a 1961 symposium discussed the question πModern Architecture: Death or Metamorphosis?11In New York, the coup d r etat appeared to materialize in controversy around the Pan Am Building that loomed over Grand Central Station, taking advantage of the modernist real estate concept of πair rights,∖[l] In criticism by Ada Louise Huxtable and Douglas Haskell it was seen to ,,severπthe Park Avenue streetscape and πtarnishπthe reputations of its consortium of architects: Walter Gropius, Pietro Belluschi and thebuilders Emery Roth & Sons. The rise of postmodernism was attributed to disenchantment with Modern architecture. By the 1980s, postmodern architecture appeared triumphant over modernism, including the temple of the Light of the World, a futuristic design for its time Guadalajara Jalisco La Luz del Mundo Sede International; however, postmodern aesthetics lacked traction and by the mid-1990s, a neo-modern (or hypermodern) architecture had once again established international pre-eminence. As part of this revival, much of the criticism of the modernists has been revisited, refuted, and re-evaluated; and a modernistic idiom once again dominates in institutional and commercial contemporary practice, but must now compete with the revival of traditional architectural design in commercial and institutional architecture; residential design continues to be dominated by a traditional aesthetic.中文译文:现代建筑现代建筑，不被混淆与‘当代建筑’，是一个词给了一些建筑风格有类似的特点，主要的简化形式,消除装饰等.虽然风格的设想早在20世纪,并大量造就了一些建筑师、建筑教育家和展品，很少有现代的建筑物，建于20世纪上半叶.第二次大战后的三十年，但最终却成为主导建筑风格的机构和公司建设.1起源一些历史学家认为进化的现代建筑作为一个社会问题，息息相关的工程中的现代性, 从而影响了启蒙运动，导致社会和政治革命.另一些人认为现代建筑主要是靠技术和工程学的发展，那就是获得新的建筑材料，如钢铁，混凝土和玻璃驱车发明新的建筑技术，它作为工业革命的一部分.1796年，Shrewsbury查尔斯bage首先用他的‘火’的设计，后者则依靠铸铁及砖与石材地板.这些建设大大加强了结构，使它们能够容纳更大的机器.由于作为建筑材料特性知识缺乏,一些早期建筑失败.直到1830年初，伊顿Hodgkinson预计推出了型钢梁，导致广泛使用钢架建设，工业结构完全改变了这种窘迫的面貌,英国北部领导的描述，〃黑暗魔鬼作坊〃的地方如曼彻斯特和西约克郡.水晶宫由约瑟夫paxton的重大展览，1851年,是一个早期的例子, 钢铁及玻璃施工；可能是一个最好的例子，就是1890年由William乐男爵延长和路易沙利文在芝加哥附近发展的高层钢结构摩天楼.早期结构采用混凝土作为行政手段的建筑表达（而非纯粹功利结构），包括建于1906年在芝加哥附近，劳埃德赖特的统一宫，建于1926 年瑞士巴塞尔附近的鲁道夫斯坦纳的第二哥特堂,.但无论原因为何，约有1900多位建筑师，在世界各地开始制定新的建筑方法,将传统的先例（比如哥特式）与新的技术相结合的可能性.路易沙利文和赖特在芝加哥工作,维克多奥尔塔在布鲁塞尔，安东尼高迪在巴塞罗那，奥托瓦格纳和查尔斯景mackintosh格拉斯哥在维也纳，其中之一可以看作是一个新与旧的共同斗争.2现代主义风格由1920年代的最重要人物，在现代建筑里确立了自己的名声.三个是公认的柯布西耶在法国，密斯范德尔德罗和瓦尔特格罗皮乌斯在德国.密斯范德尔德罗和格罗皮乌斯为董事的包豪斯，其中欧洲有不少学校和有关团体学习调和工艺和传统工业技术.赖特的建筑生涯中，也影响了欧洲建筑的现代艺术,特别是通过瓦斯穆特组合但他拒绝被归类与他们.赖特与格罗皮乌斯和Van der德罗对整个有机体系有重大的影响.在1932年来到的重要moma展览,是现代建筑艺术的国际展览，艺术家菲利普约翰逊. 约翰逊和合作者亨利-罗素阁纠集许多鲜明的线索和趋势，内容相似,有一个共同的目的, 巩固了他们融入国际化风格这是一个重要的转折点.在二战的时间包豪斯的代表人物逃到美国，芝加哥，到哈佛大学设计黑山书院.当现代建筑设计从未成为主导风格单一的住宅楼，在成为现代卓越的体制和商业建筑，是学校（专业领导）的唯一可接受的，设计解决方案，从约1932年至约1984 年.那些从事国际风格的建筑师想要打破传统建筑和简单的没有装饰的建筑物。

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

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

This paper explores the potential effects of AI on various industries, including healthcare, manufacturing, and transportation, and the implications for employment. The findings suggest that while AI has the potential to automate repetitive tasks and increase productivity, it may also lead to job displacement and a shift in job requirements. The paper concludes with a discussion on the importance of upskilling and retraining for workers to adapt to the changing job market.1. IntroductionArtificial intelligence (AI) refers to the development of computer systems that can perform tasks that typically require human intelligence. AI has made significant advancements in recent years, with applications in various industries, such as healthcare, manufacturing, and transportation. As AI technology continues to evolve, concerns arise about its impact on the job market. This paper aims to explore the potential effects of AI on employment and discuss the implications for workers.2. Potential Effects of AI on the Job Market2.1 Automation of Repetitive TasksOne of the major impacts of AI on the job market is the automation of repetitive tasks. AI systems can perform tasks faster and moreaccurately than humans, particularly in industries that involve routine and predictable tasks, such as manufacturing and data entry. This automation has the potential to increase productivity and efficiency, but also poses a risk to jobs that can be easily replicated by AI.2.2 Job DisplacementAnother potential effect of AI on the job market is job displacement. As AI systems become more sophisticated and capable of performing complex tasks, there is a possibility that workers may be replaced by machines. This is particularly evident in industries such as transportation, where autonomous vehicles may replace human drivers, and customer service, where chatbots can handle customer inquiries. While job displacement may lead to short-term unemployment, it also creates opportunities for new jobs in industries related to AI.2.3 Shifting Job RequirementsWith the introduction of AI, job requirements are expected to shift. While AI may automate certain tasks, it also creates a demand for workers with the knowledge and skills to develop and maintain AI systems. This shift in job requirements may require workers to adapt and learn new skills to remain competitive in the job market.3. Implications for EmploymentThe impact of AI on employment is complex and multifaceted. On one hand, AI has the potential to increase productivity, create new jobs, and improve overall economic growth. On the other hand, it may lead to job displacement and a shift in job requirements. To mitigate the negative effects of AI on employment, it is essentialfor workers to upskill and retrain themselves to meet the changing demands of the job market.4. ConclusionIn conclusion, the rapid development of AI has significant implications for the job market. While AI has the potential to automate repetitive tasks and increase productivity, it may also lead to job displacement and a shift in job requirements. To adapt to the changing job market, workers should focus on upskilling and continuous learning to remain competitive. Overall, the impact of AI on employment will depend on how it is integrated into various industries and how workers and policymakers respond to these changes.。

(1989). The Poetics of City and Nature: T oward a New Aesthetic for UrbanDesign. Places, 6(1), 82.Keywords:places, placemaking, architecture, environment, landscape, urban design, public realm, planning, design, aesthetic, poetics, Anne Whiston SpirnThe city has been compared to a poem, a sculpture, a machine. But the city is more than a text,and more than an artistic or technological. It is a place where natural forces pulse and millions of people live—thinking,feeling,dreaming,doing. An aesthetic of urban design must therefore be rooted in the normal processes of nature and of living.I want to describe the dimensions of such an aesthetic. This aesthetic encompasses both nature and culture; it embodies function,sensory perception, and symbolic meaning; and it embraces both the making of things and places and the sensing, using, and contemplating of them. This aesthetic is concerned equally with everyday things and with art: with small things, such as fountains, gardens, and buildings, and with large systems, such as those that transport people or carry wastes. This aesthetic celebrates motion and change, encompasses dynamic processes rather than static objects and scenes, and embraces multiple rather than singular visions. This is not a timeless aesthetic, but one that recognizes both the flow of passing time and the singularity of the moment in time, and one that demands both continuity and revolution.Urban form evolves in time,in predictable and unpredictable ways, the result of complex, overlapping, and interweaving dialogues. These dialogues are all present and ongoing; some are sensed intuitively;others are clearly legible. Together, they comprise the context of a place and all those who dwell within it.This idea of dialogue, with its embodiment of time, purpose, communication, and response, os central to this aesthetic.Concomitant with the need for continuity in the urban landscape is the need for revolution. Despite certain constants of nature and human nature, we live in a worldunimaginable to societies of the past. Our perceptions of nature, the quality of its order,and the nature of time and space are changing, as is our culture, provoking the reassessment of old forms and demanding new ones. The vocabulary of forms—buildings, streets, and parks—that are often deferred to as precedents not only reflects a response to cultural processes and values of the time in which those forms were created. Some of these patterns and forms sill express contemporary purposes and values, but they are abstractions. What are the forms that express contemporary cosmology, that speak to us in an age in which photographs of atomic particles and of galaxies are commonplace, in which time and space are not fixed, but relative, and in which we are less certain of our place in the universe than we once were? Conceiving of new forms that capture the knowledge, beliefs, purposes, and values of contemporary society demands that we return to the original source of inspiration, be it nature or culture,rather than the quotation or transformation of abstractions of the past.Time,Change,and Rhythm"For the artist," observed Paul Klee," dialogue with nature remains a conditiosine que non. The artist is a man, himself nature and part of nature in natural space." Before humans built towns and cities, our habitat was ordered primarily by nature's processes. The most intimate rhythms of the human body are still conditioned by the natural world outside ourselves: the daily path of the sun, alternating light with dark; the monthly phases of the moon, tugging the tides; and the annual passage of the seasons.In contrast to the repetitive predictability of daily and seasonal change is the immensity of the geological time scale. From a view of the world that measured the age of the earth in human generations, we have come to calculate the earth's age in terms of thousands of millions of years and have developed theories of the earth itself. The human life span now seems but a blip, and the earth but a small speck in the universe.The perception of time and change is essential to developing a sense of who we are, where we have come form, and where we are going, as individuals, societies, and species. Design that fosters and intensifies the experience of temporal and spatial scales facilitates both a reflection upon personal change and identity and a sense of unity with a larger whole. Design that juxtaposes and contrasts nature's order and human order prompts contemplation of what if means to be human. Design that resonates with a place's natural and cultural rhythms, that echoes, amplifies, clarifies, or extends them, contributes to a sense of rootedness in space time.Process,Pattern,and FormGreat,upright, red rocks,thrust from the earth,rising hundreds of feet, strike the boundary between mountain and plain along the Front Range of the Rockies. Red Rocks Amphitheater is set in these foothills, its flat stage dwarfed by the red slabs that frame it and the panoramic view out across the city of Denver, Colorado and the Great Plains. The straight lines of the terraced seats, cut from sandstone to fit the human body, and the tight curve of the road, cut to fit the turning car, seem fragile next to the rocks' awesome scale and magnificent geometry.Denver is a city of high plains, Nestled up against these foothills, it rests on sedimentsmany hundreds of feet deep, their fine grains eroded from the slopes of ancient mountains that once rested atop the Rockies, their peaks high above the existing mountains. The red slabs are the ruined roots of those ancient mountain peaks, remnants of rock layers that once arched high over the Rockies we know today. As the eye follows the angle of their thrust and completes that arc, one is transported millions of years into the past. This is the context of Denver, a context in space and time created by the enduring rhythm of nature's processes and recorded in patterns in the land. The amphitheater affords not only a view of the city, but also a prospect for reflecting upon time, change, and the place of man and city in nature.When we neglect natural processes in city design, we not only risk the intensification of natural hazards and the degradation of natural resources, but also forfeit a sense of connection to a larger whole beyond ourselves. In contrast, places such as Red Rocks Amphitheater provoke a vivid experience of natural processes that permits us to extend our imagination beyond the limits of human memory into the reaches of geological and astronomical time and to traverse space from the microscopic to the cosmic. However permanent rock may seem, it is ultimately worn smooth by water and reduced finally to dust. The power of a raindrop, multiplied by the trillions over thousands into plains. The pattern of lines etched by the water in the sand of a beach echos the pattern engraved on the earth by rivers over time.These are the patterns that connect. They connect us to scales of space and time beyond our grasp; they connect our bodies and minds to the pulse of the natural world outside our skin. The branching riverbed cut by flowing water and the branching tree within which the sap rises are patterns that mirror the branching arteries and veins through which our blood courses.Patterns formed by nature's processes and their symmetry across scales have long been appreciated by close observers of the natural world. Recent developments in science afford new insights into the geometry of form generated by dynamic processes, be they natural or cultural, and point to new directions for design.The forms of mountain ranges, riverbanks, sand dunes, trees, and snow crystals, are poised, jelled, at a moment in time, the physical embodiment of dynamic processes. Their beauty consists of a peculiar combination of order and disorder, harmoniously arranged, and the fact that their forms are at equilibrium, at any given moment, with the processes that produced them. Such forms and the phenomenon of their symmetry across scales of time and space, have recently been described by a new geometry,"fractal" geometry, which one of its originators, Benoit Mandelbrot calls "the geometry of nature"—"pimply,""pocky,""tortuous," and "intertwined." A sensibility steeped in classical geometry perceivers these forms as too complex to descibe.However, as fractals, such patterns can be described with simplicity, the result of repetitive processes, such as bifurcation and development. The variety of forms that stem from the same process os the result of response to differing conditions of context, of to the interaction with other processes.Strange and wonderful forms, mirroring those of nature, have been created by repeating a single computer program. Early in the process, the resulting form, as seen on the computer screen appears chaotic; gradually an order unfolds. Such experiments are thesubject of a new field,coined Chaos by its pioneers, who feel that they are defining a new paradigm. Their subjects are diverse, their objective is to identify the underlying order in seemingly random fluctuations. Many of those working in field have expressed their aesthetic attraction to the mathematics of fractal geometry in contrast to what they term the "Euclidean sensibility."This is a geometry foreign to that of Euclid, with its lines and planes, circles and spheres, triangles and cones. Euclidean geometry is an abstraction of reality; its beauty lies in smooth, clean, ideal shapes. It is a geometry based on the belief that rest, not motion, is the natural state; it describes three-dimensional space but neglects time.That does not mean that we should avoid using Euclidean geometry in the design of landscapes. Indeed, such use may heighten our perception of the natural forms of rivers and trees and the processes that produce them, especially when it is employed as a visual counterpoint that both expresses and contrasts with those forms.In Dinan, France, a monumental are of poplars takes its inspiration from the sweeping out the irregularities of the river bank. The are represents the idea of that sweep. Through the abstraction and echo of the horizontal form in the vertical dimension, in what is clearly a line inscribed by humans on the landscape, the experience of the river's meander is intensified. Though set in a tight,evenly-spaced row along the banks of the river, the individual trees assert their own quirky growth, which is seen more clearly in contrast to the regularity of their placement.The interplay of different processes is also a subject of current research on "chaos." Computer drawings illustrate the patterns that result when several rhythms, such as radio frequencies or planetary orbits, come together. Perhaps this is the contemporary version of the "music of the spheres." They resemble a topographic contour map,prompting the realization that land form results from a similar interplay among multiple forces and processes, including gravity, water flow, and weather. Cultural processes also engage natural processes on the land; the rhythms of food production and transportation, for example, interact with the flow of wind and water to mold a landscape. The patterns that result vary in response to the specific context of natural environment, culture, and the idiosyncrasies of individuals.It is nature and culture together, as interacting processes, that render a place particular. Natural processes operating over time give rise to the initial form of the land and comprise the base rhythm to which the cultural processes respond, introducing new and changing themes, weaving an intricate pattern, punctuated here and there by high points of nature and art. Every urban landscape is a symphony of complex harmonies, which, although they can be savored at any given moment,evolve continually in time, in both predictable and unpredictable ways, in response natural processes and changing human purposes. It is a symphony in which all the dwellers of the city are composers and players.Making, Caring, Thinking, DwellingThe process of dwelling,an irreducible fact of every culture, is an aesthetic act, entailing being and doing, a correspondence between nature and culture. Through cultivation and construction, individuals and societies forge a place within nature that reflects their own identities—their needs, values, and dream. Making and caring for a place,as well as contemplating these labors and their meanings, comprise the aesthetic experience of dwelling.This concept, as explored by the philosopher Heidegger, has important implications for designers and planners of human settlements. A major issue for designers is how to relinquish control (whether to enable others to express themselves or to permit nature's processes to take their course) while still maintaining an aesthetically pleasing order. The pleasing quality of the allotment gardens of community gardens that are popular in both European and North American cities depends upon a gridded framework of plots. Each garden plot is a whole in itself, an improvisation on similar themes by different individuals. Yet all are part of a whole unified by materials, structure, and the process of cultivation.In Granada, Spain, allotment gardens lie within the Alhambra and Generalife. The gardens rest within a highly organized framework of walls and terraces, and enliven the scene rather than detract from it. They complement the formal gardens and courtyards,where vegetables and nut and fruit trees are planted among flowers and vines. There is no arbitrary separation in this Moorish garden between ornamental and productive, between pleasurable and pragmatic,between sacred and secular.It is possible to create urban landscapes that capture a sense of complexity and underlying order,that express a connection to the natural and cultural history of the place, and that are adaptable to meet changing needs. The solution lies in an understanding of the processes that underlie these patterns, and there are some principles that can be derived for urban design:establish a framework that lends overall structure—not an arbitrary framework, but one congruent with the "deep" structure of a place, define a vocabulary of forms that expresses natural and cultural processes, the encourage a symphony of variations in response to the conditions of a particular locale and the needs of specific people. The result should be a dynamic, coherent whole that can contine to evolve to meet changing neeeds and desires and that also connects the present with the past.The Fens, in Boston, is such a place. As originally conceived and constructed in the 1880s and '90s ,the Fens and its extension in the Riverway were innovative models for public open space that integrated engineering, economics, and aesthetics. The Fens and the Riverway created an integrated system of park, parkway, storm drain, flood detention basin, and streetcar line that formed the skeleton for the growth of adjacent neighborhoods.Frederick Law Olmsted and his partners designed the Fens as a salt water marsh that would function as a flood control reservoir and that would be a counterpoint to the surrounding city. This marsh was human construct dug out of polluted mudflats, but it was designed to appear like a natural salt marsh around which the city had happened to grow. Time and chang, process and purpose are expressed by its shape-a bowl with an irregular edge-and the pattern of plants-bands of grasses and shrubs variably tolerant of fluctuating water levels; even when riverflow was low, its form recalled that it was designed to receive.Olmsted's imitation of nature represents a divergence from the then prevailing pastoral and formal styles, both of which were domesticated landscapes and abstractions of nature. The fens and the Riverway, in their time, represented a new aesthetic for the urban districts which grew up around them, of sufficient scale to hold their own against the large buildings at their edge, and recalling the original condition of the land prior to colonial。

建筑文化根植于人居自然环境之中不同的地域自然有不同的自然环境：地形地貌、日照角度、日月潮汐、水流风势、气温、气压、食物、土地、水质、植被等等。
作为人与自然中介的建筑,对外应有利于形成小区外部环境，对内应有利于保障人居的室内环境。
这些建筑像植物一样，落地生根,合天时,合地利，适宜于地区自然环境的要求,与大自然融为一体。
在东南亚和南亚各国,在中国的海南岛和台湾岛，椰林茂密，气候炎热,人们用椰树叶、棕榈叶盖起了适应热带雨林的茅草房、小木楼,通风、凉爽、轻盈、简洁,建起了热带雨林建筑。
在中亚、西亚，在中国的西部高寒地区,人们用石块垒砌、依山就势盖起了石板建筑，避风、挡雪、保温、御寒,筑成了高原山地建筑。
如中国的西藏、青海、四川等少数民族在中国西部依山就势建起了各式各样的山地建筑群。
在中国的黄土高原，漠北戈壁，雨量稀少，气候干燥，人们利用山边、土坡挖洞筑房,建起了具有鲜明特色的生土建筑。
甘肃敦煌艺术陈列馆把建筑埋入山坡下,半开敞式入口,山坡挡墙甬道,生土式建筑特征十分明显。
在美国的东部，在澳大利亚,在中国的南方,雨量充沛，气候温和，人们用木材、砖瓦依山就势，因地制宜,盖起了遮阳避雨、通风透气、造型别致的湿热地区建筑。
这些建筑形式多样，风格各异，适宜于不同地区自然环境,与风景、林木、地形融为一体，形成了根植于自然环境的各种建筑文化。
建筑既要根植于自然环境,又要服从于自然环境,这是建筑师必须遵循的一条基本原则。
社会时空环境差异造成建筑文化的多元化不同的地域、不同的国家、不同的民族,有不同的社会历史形态。
欧洲国家、美洲国家、亚洲与非洲等发展中国家，国度不同，宗教信仰不同，经济发展状况不同,各地区的文化习俗也不同。
不同地区的人居社会时空环境的差异，造成了建筑文化的时空性和多元性，因而产生了古代的或现代的中国建筑文化、俄罗斯建筑文化、东南亚建筑文化、欧美建筑文化、非洲建筑文化等等。
欧洲的古希腊建筑、北非的古埃及建筑、南亚的古印度建筑、古代中国建筑是世界民族建筑文化的历史源流。

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

德黑兰市的发展全市已长成了一定的规模性和复杂性，以这样的程度，空间管理需要另外的手段来处理城市组织和不断发展的复杂性，并为城市总体规划做准备。
第二次世界大战后，在盟军占领国家的期间，有一个时期的民主化，在冷战时开始的政治紧张局势之后，它们互相斗争对石油的控制权。
这个时期已经结束于1953年，结果是由政变产生了伊朗王，那个后来担任了25年的行政君主的人。
随着高出生率和农村向城市迁移，德黑兰和其他大城市增长加剧甚至比以前更快地。
到1956年，德黑兰的人口上升到150万，到了1966至300万， 1976至450万，其规模也从1934年46平方公里到1976年的250平方公里。
从石油行业的收入增长创造的盈余资源，需要流通和经济的吸收。
50年代中期，特别是在工业化的驱动下德黑兰许多大城市有了新工作。

毕业设计（论文）外文文献原文及译文Chapter 11. Cipher Techniques11.1 ProblemsThe use of a cipher without consideration of the environment in which it is to be used may not provide the security that the user expects. Three examples will make this point clear.11.1.1 Precomputing the Possible MessagesSimmons discusses the use of a "forward search" to decipher messages enciphered for confidentiality using a public key cryptosystem [923]. His approach is to focus on the entropy (uncertainty) in the message. To use an example from Section 10.1(page 246), Cathy knows that Alice will send one of two messages—BUY or SELL—to Bob. The uncertainty is which one Alice will send. So Cathy enciphers both messages with Bob's public key. When Alice sends the message, Bob intercepts it and compares the ciphertext with the two he computed. From this, he knows which message Alice sent.Simmons' point is that if the plaintext corresponding to intercepted ciphertext is drawn from a (relatively) small set of possible plaintexts, the cryptanalyst can encipher the set of possible plaintexts and simply search that set for the intercepted ciphertext. Simmons demonstrates that the size of the set of possible plaintexts may not be obvious. As an example, he uses digitized sound. The initial calculations suggest that the number of possible plaintexts for each block is 232. Using forward search on such a set is clearly impractical, but after some analysis of the redundancy in human speech, Simmons reduces the number of potential plaintexts to about 100,000. This number is small enough so that forward searches become a threat.This attack is similar to attacks to derive the cryptographic key of symmetric ciphers based on chosen plaintext (see, for example, Hellman's time-memory tradeoff attack [465]). However, Simmons' attack is for public key cryptosystems and does not reveal the private key. It only reveals the plaintext message.11.1.2 Misordered BlocksDenning [269] points out that in certain cases, parts of a ciphertext message can be deleted, replayed, or reordered.11.1.3 Statistical RegularitiesThe independence of parts of ciphertext can give information relating to the structure of the enciphered message, even if the message itself is unintelligible. The regularity arises because each part is enciphered separately, so the same plaintext always produces the same ciphertext. This type of encipherment is called code book mode, because each part is effectively looked up in a list of plaintext-ciphertext pairs.11.1.4 SummaryDespite the use of sophisticated cryptosystems and random keys, cipher systems may provide inadequate security if not used carefully. The protocols directing how these cipher systems are used, and the ancillary information that the protocols add to messages and sessions, overcome these problems. This emphasizes that ciphers and codes are not enough. The methods, or protocols, for their use also affect the security of systems.11.2 Stream and Block CiphersSome ciphers divide a message into a sequence of parts, or blocks, and encipher each block with the same key.Definition 11–1. Let E be an encipherment algorithm, and let Ek(b) bethe encipherment of message b with key k. Let a message m = b1b2…, whereeach biis of a fixed length. Then a block cipher is a cipher for whichE k (m) = Ek(b1)Ek(b2) ….Other ciphers use a nonrepeating stream of key elements to encipher characters of a message.Definition 11–2. Let E be an encipherment algorithm, and let Ek(b) bethe encipherment of message b with key k. Let a message m = b1b2…, whereeach bi is of a fixed length, and let k = k1k2…. Then a stream cipheris a cipher for which Ek (m) = Ek1(b1)Ek2(b2) ….If the key stream k of a stream cipher repeats itself, it is a periodic cipher.11.2.1 Stream CiphersThe one-time pad is a cipher that can be proven secure (see Section 9.2.2.2, "One-Time Pad"). Bit-oriented ciphers implement the one-time pad by exclusive-oring each bit of the key with one bit of the message. For example, if the message is 00101 and the key is 10010, the ciphertext is01||00||10||01||10 or 10111. But how can one generate a random, infinitely long key?11.2.1.1 Synchronous Stream CiphersTo simulate a random, infinitely long key, synchronous stream ciphers generate bits from a source other than the message itself. The simplest such cipher extracts bits from a register to use as the key. The contents of the register change on the basis of the current contents of the register.Definition 11–3. An n-stage linear feedback shift register (LFSR)consists of an n-bit register r = r0…rn–1and an n-bit tap sequence t =t 0…tn–1. To obtain a key bit, ris used, the register is shifted one bitto the right, and the new bit r0t0⊕…⊕r n–1t n–1 is inserted.The LFSR method is an attempt to simulate a one-time pad by generating a long key sequence from a little information. As with any such attempt, if the key is shorter than the message, breaking part of the ciphertext gives the cryptanalyst information about other parts of the ciphertext. For an LFSR, a known plaintext attack can reveal parts of the key sequence. If the known plaintext is of length 2n, the tap sequence for an n-stage LFSR can be determined completely.Nonlinear feedback shift registers do not use tap sequences; instead, the new bit is any function of the current register bits.Definition 11–4. An n-stage nonlinear feedback shift register (NLFSR)consists of an n-bit register r = r0…rn–1. Whenever a key bit is required,ris used, the register is shifted one bit to the right, and the new bitis set to f(r0…rn–1), where f is any function of n inputs.NLFSRs are not common because there is no body of theory about how to build NLFSRs with long periods. By contrast, it is known how to design n-stage LFSRs with a period of 2n– 1, and that period is maximal.A second technique for eliminating linearity is called output feedback mode. Let E be an encipherment function. Define k as a cryptographic key,(r) and define r as a register. To obtain a bit for the key, compute Ekand put that value into the register. The rightmost bit of the result is exclusive-or'ed with one bit of the message. The process is repeated until the message is enciphered. The key k and the initial value in r are the keys for this method. This method differs from the NLFSR in that the register is never shifted. It is repeatedly enciphered.A variant of output feedback mode is called the counter method. Instead of using a register r, simply use a counter that is incremented for every encipherment. The initial value of the counter replaces r as part of the key. This method enables one to generate the ith bit of the key without generating the bits 0…i – 1. If the initial counter value is i, set. In output feedback mode, one must generate all the register to i + ithe preceding key bits.11.2.1.2 Self-Synchronous Stream CiphersSelf-synchronous ciphers obtain the key from the message itself. The simplest self-synchronous cipher is called an autokey cipher and uses the message itself for the key.The problem with this cipher is the selection of the key. Unlike a one-time pad, any statistical regularities in the plaintext show up in the key. For example, the last two letters of the ciphertext associated with the plaintext word THE are always AL, because H is enciphered with the key letter T and E is enciphered with the key letter H. Furthermore, if theanalyst can guess any letter of the plaintext, she can determine all successive plaintext letters.An alternative is to use the ciphertext as the key stream. A good cipher will produce pseudorandom ciphertext, which approximates a randomone-time pad better than a message with nonrandom characteristics (such as a meaningful English sentence).This type of autokey cipher is weak, because plaintext can be deduced from the ciphertext. For example, consider the first two characters of the ciphertext, QX. The X is the ciphertext resulting from enciphering some letter with the key Q. Deciphering, the unknown letter is H. Continuing in this fashion, the analyst can reconstruct all of the plaintext except for the first letter.A variant of the autokey method, cipher feedback mode, uses a shift register. Let E be an encipherment function. Define k as a cryptographic(r). The key and r as a register. To obtain a bit for the key, compute Ek rightmost bit of the result is exclusive-or'ed with one bit of the message, and the other bits of the result are discarded. The resulting ciphertext is fed back into the leftmost bit of the register, which is right shifted one bit. (See Figure 11-1.)Figure 11-1. Diagram of cipher feedback mode. The register r is enciphered with key k and algorithm E. The rightmost bit of the result is exclusive-or'ed with one bit of the plaintext m i to produce the ciphertext bit c i. The register r is right shifted one bit, and c i is fed back into the leftmost bit of r.Cipher feedback mode has a self-healing property. If a bit is corrupted in transmission of the ciphertext, the next n bits will be deciphered incorrectly. But after n uncorrupted bits have been received, the shift register will be reinitialized to the value used for encipherment and the ciphertext will decipher properly from that point on.As in the counter method, one can decipher parts of messages enciphered in cipher feedback mode without deciphering the entire message. Let the shift register contain n bits. The analyst obtains the previous n bits of ciphertext. This is the value in the shift register before the bit under consideration was enciphered. The decipherment can then continue from that bit on.11.2.2 Block CiphersBlock ciphers encipher and decipher multiple bits at once, rather than one bit at a time. For this reason, software implementations of block ciphers run faster than software implementations of stream ciphers. Errors in transmitting one block generally do not affect other blocks, but as each block is enciphered independently, using the same key, identical plaintext blocks produce identical ciphertext blocks. This allows the analyst to search for data by determining what the encipherment of a specific plaintext block is. For example, if the word INCOME is enciphered as one block, all occurrences of the word produce the same ciphertext.To prevent this type of attack, some information related to the block's position is inserted into the plaintext block before it is enciphered. The information can be bits from the preceding ciphertext block [343] or a sequence number [561]. The disadvantage is that the effective block size is reduced, because fewer message bits are present in a block.Cipher block chaining does not require the extra information to occupy bit spaces, so every bit in the block is part of the message. Before a plaintext block is enciphered, that block is exclusive-or'ed with the preceding ciphertext block. In addition to the key, this technique requires an initialization vector with which to exclusive-or the initial plaintext block. Taking Ekto be the encipherment algorithm with key k, and I to be the initialization vector, the cipher block chaining technique isc 0 = Ek(m⊕I)c i = Ek(mi⊕ci–1) for i > 011.2.2.1 Multiple EncryptionOther approaches involve multiple encryption. Using two keys k and k' toencipher a message as c = Ek' (Ek(m)) looks attractive because it has aneffective key length of 2n, whereas the keys to E are of length n. However, Merkle and Hellman [700] have shown that this encryption technique can be broken using 2n+1encryptions, rather than the expected 22n(see Exercise 3).Using three encipherments improves the strength of the cipher. There are several ways to do this. Tuchman [1006] suggested using two keys k and k':c = Ek (Dk'(Ek(m)))This mode, called Encrypt-Decrypt-Encrypt (EDE) mode, collapses to a single encipherment when k = k'. The DES in EDE mode is widely used in the financial community and is a standard (ANSI X9.17 and ISO 8732). It is not vulnerable to the attack outlined earlier. However, it is vulnerable to a chosen plaintext and a known plaintext attack. If b is the block size in bits, and n is the key length, the chosen plaintext attacktakes O(2n) time, O(2n) space, and requires 2n chosen plaintexts. The known plaintext attack requires p known plaintexts, and takes O(2n+b/p) time and O(p) memory.A second version of triple encipherment is the triple encryption mode [700]. In this mode, three keys are used in a chain of encipherments.c = Ek (Ek'(Ek''(m)))The best attack against this scheme is similar to the attack on double encipherment, but requires O(22n) time and O(2n) memory. If the key length is 56 bits, this attack is computationally infeasible.11.3 Networks and CryptographyBefore we discuss Internet protocols, a review of the relevant properties of networks is in order. The ISO/OSI model [990] provides an abstract representation of networks suitable for our purposes. Recall that the ISO/OSI model is composed of a series of layers (see Figure 11-2). Each host, conceptually, has a principal at each layer that communicates with a peer on other hosts. These principals communicate with principals at the same layer on other hosts. Layer 1, 2, and 3 principals interact only with similar principals at neighboring (directly connected) hosts. Principals at layers 4, 5, 6, and 7 interact only with similar principals at the other end of the communication. (For convenience, "host" refers to the appropriate principal in the following discussion.)Figure 11-2. The ISO/OSI model. The dashed arrows indicate peer-to-peer communication. For example, the transport layers are communicating with each other. The solid arrows indicate the actual flow of bits. For example, the transport layer invokes network layer routines on the local host, which invoke data link layer routines, which put the bits onto the network. The physical layer passes the bits to the next "hop," or host, on the path. When the message reaches the destination, it is passed up to the appropriatelevel.Each host in the network is connected to some set of other hosts. They exchange messages with those hosts. If host nob wants to send a message to host windsor, nob determines which of its immediate neighbors is closest to windsor (using an appropriate routing protocol) and forwards the message to it. That host, baton, determines which of its neighbors is closest to windsor and forwards the message to it. This process continues until a host, sunapee, receives the message and determines that windsor is an immediate neighbor. The message is forwarded to windsor, its endpoint.Definition 11–5. Let hosts C0, …, Cnbe such that Ciand Ci+1are directlyconnected, for 0 i < n. A communications protocol that has C0 and Cnasits endpoints is called an end-to-end protocol. A communications protocolthat has Cj and Cj+1as its endpoints is called a link protocol.The difference between an end-to-end protocol and a link protocol is that the intermediate hosts play no part in an end-to-end protocol other than forwarding messages. On the other hand, a link protocol describes how each pair of intermediate hosts processes each message.The protocols involved can be cryptographic protocols. If the cryptographic processing is done only at the source and at the destination, the protocol is an end-to-end protocol. If cryptographic processing occurs at each host along the path from source to destination, the protocolis a link protocol. When encryption is used with either protocol, we use the terms end-to-end encryption and link encryption, respectively.In link encryption, each host shares a cryptographic key with its neighbor. (If public key cryptography is used, each host has its neighbor's public key. Link encryption based on public keys is rare.) The keys may be set on a per-host basis or a per-host-pair basis. Consider a network with four hosts called windsor, stripe, facer, and seaview. Each host is directly connected to the other three. With keys distributed on a per-host basis, each host has its own key, making four keys in all. Each host has the keys for the other three neighbors, as well as its own. All hosts use the same key to communicate with windsor. With keys distributed on a per-host-pair basis, each host has one key per possible connection, making six keys in all. Unlike the per-host situation, in the per-host-pair case, each host uses a different key to communicate with windsor. The message is deciphered at each intermediate host, reenciphered for the next hop, and forwarded. Attackers monitoring the network medium will not be able to read the messages, but attackers at the intermediate hosts will be able to do so.In end-to-end encryption, each host shares a cryptographic key with each destination. (Again, if the encryption is based on public key cryptography, each host has—or can obtain—the public key of each destination.) As with link encryption, the keys may be selected on a per-host or per-host-pair basis. The sending host enciphers the message and forwards it to the first intermediate host. The intermediate host forwards it to the next host, and the process continues until the message reaches its destination. The destination host then deciphers it. The message is enciphered throughout its journey. Neither attackers monitoring the network nor attackers on the intermediate hosts can read the message. However, attackers can read the routing information used to forward the message.These differences affect a form of cryptanalysis known as traffic analysis.A cryptanalyst can sometimes deduce information not from the content ofthe message but from the sender and recipient. For example, during the Allied invasion of Normandy in World War II, the Germans deduced which vessels were the command ships by observing which ships were sending and receiving the most signals. The content of the signals was not relevant; their source and destination were. Similar deductions can reveal information in the electronic world.第十一章密码技术11．1问题在没有考虑加密所要运行的环境时，加密的使用可能不能提供用户所期待的安全。

第一部部分外文文献原文部分中文2000字New thinking of contemporary western architecturalaestheticsOne of the most striking features of aesthetics of contemporary western architecture, is the change of aesthetic thinking. It is a rich epoch-making revolutionary change. As we know, the aesthetic thought of modern architecture, basically confined to the overallthinking, linear thinking, rational thinking this fixed,and even can be said to be rigid frame, it is difficult tobreak through the shackles of functionalism, rationalism. However, at present, in and promote the dual influence ofwestern contemporary philosophical and scientific thought, had the historical transformation of aesthetic thinking of contemporary architecture. It is completely out of thegeneral, linear and rational thinking inertia, towards anew thinking for a more contemporary nature's way.Non overall thinkingModern architectural geometry hegemony and pure aesthetics basically is a kind of in a flagrant way"oppressive totalisation" (his words) to control and guide the construction of aesthetic trend. When V enturi, Philip? Johnson et al to challenge the "oppressive totalisation", when the modern movement has become thriving in the construction field, modern unified pattern was quicklybroken, overall tanked. Unfortunately, when the postmodern architecture emerge in large numbers, the architects soon felt, they are likely to be as Jaspers said, "from a situation into another kind of situation", from an overall fall into another kind of overall. This replaces the aesthetic revolution another tyranny in a dictatorship, is a contemporary architects and scientists do not want to see, most cannot accept, therefore, all sorts of new architectural concepts since the anti-modernist movementuntil the emergence of resistance, all to the overall,pursuit diversity as a preventive and expel any form ofaesthetic autocracy charm monster banner.Adorno (Theodor W ? Adoeno, German philosopher) said, "the liberation of mankind does not mean to become a general". In order to carry out the communication and understanding between different races of human, reallyneed a standard of value, common ideals andcommon feelings,however, this does not mean that, human's political institutions, customs should follow the same general. Onthe aesthetic, specifically, on art and architecture, the general can only is an inert strength, even can say, it is the most terrible enemy of creativity.Terrible place overall is, it has a periodic attackmorbid inertial forces. When a art of totality was a fatal blow when, often is another kind of overall quietly out of. So Adorno thinks, if art is always a radical, it is always conservative. The strengthening phase separation and the dominant spirit of the illusion, "which in practice isinvalid and complicit did not reduce disaster is apparently painful". It was in one direction, and lost in the otherdirection; if art to bypass the disgraced historical logic, then it will have to pay a high price for this free, oneof which is difficult to meet the reproduction of historical logic. Adorno to escape from the overall hasbeen holding a contradiction, suspicion and even pessimistic attitude. He said, we can ignore the totality, but overall did not ignore us. As if the general is a kindof come a nd go like a shadow, as the shadow follows the form, unable to get rid of stuff. In his view, fled the totalityis neither possible nor necessary. Because you are against the general, "get in one direction, and lost in anotherdirection". However, most architects do not agree with his point of view, their ability to hope that through improvethe architects attention, perception and choice, give full play to the architect of the autonomy and capture and expression ability difference, in order to escape from the trap of totality.Philip? Judi Di ou (Philip Jodidio) Stephen Holzerknown as the ideological Architects (Steven Holl) said:"the unified construction and its compliance technique or style, irrational open let it to a place. It should be the same tendency to resist standardization...... New buildings must be formed in this way: it is a cross-cultural continuous adaptation, and poetic performance and personal environment and community adaptation." Holzer clearly opposed to any form of identity or overall, his ideal architecture, is both personal survival culture situation and environmental situation, but also has a certain heterogeneity architecture.Mofuxisi firm commanding general Tom Men has alwaysbeen a personal independence ofconduct is known, althoughhe did not like Bernard Tschumi and Michael Sorkin (Michael Sorkin), call ugly building, but he to architectural formand style and he ignored almost of the building structureand spatial attention as famous. He mounted the spell,false postmodernism with deep aversion, to the 80's popular false pluralism is a contemptuous disregard. He once said, "today, we have the common value system of evaluation ofour diverse world, in this world, the reality is chaotic, unpredictable, so it is unknown. The adventure has becomeour principles of operation...... One o f the central themes of today's building, is about an architect can in our environment, corrosion of autonomy, our sense of self and personal mental psychological and social forces independent action problem from within." Main and his researchers cooperation, attaches great importance to the art creation and personal independence. In their view, the individual should not be affected by the grand narrative(Grand Narrative) influence, should not be subject to themacro rationality, and should follow the guidelines forcreating self pure mission, go "narrative" that personalized road. Only in this way, the building can getrid of the same sex and overall cycle.With the design of Vienna Z bank G. Domini (Gunther Domenig), and the blue sky group Wolf? S (Wolf Prix) apparently Rex the building as a kind of narration andexpression of art. He sincerely hopes to the architect'sdesign and the writer's creation, fully draw, revelationand expression of complexity and diversity of our world.He said: "we should find a enough to reflect the complexity of the diversity of our world and society.第二部位中文对照翻译部分当代西方建筑美学新思维当代西方建筑美学最显著的特征之一，就是审美思维的变化。
