High-Rise Buildings
Introduction
It is difficult to define a high-rise building . One may say that a low-rise building ranges from 1 to 2 stories . A medium-rise building probably ranges between 3 or 4 stories up to 10 or 20 stories or more .
Although the basic principles of vertical and horizontal subsystem design remain the same for low- , medium- , or high-rise buildings , when a building gets high the vertical subsystems become a controlling problem for two reasons . Higher vertical loads will require larger columns , walls , and shafts . But , more significantly , the overturning moment and the shear deflections produced by lateral forces are much larger and must be carefully provided for .
The vertical subsystems in a high-rise building transmit accumulated gravity load from story to story , thus requiring larger column or wall sections to support such loading . In addition these same vertical subsystems must transmit lateral loads , such as wind or seismic loads , to the foundations. However , in contrast to vertical load , lateral load effects on buildings are not linear and increase rapidly with increase in height . For example under wind load , the overturning moment at the base of buildings varies approximately as the square of a buildings may vary as the fourth power of buildings height , other things being equal. Earthquake produces an even more pronounced effect.
When the structure for a low-or medium-rise building is designed for dead and live load , it is almost an inherent property that the columns , walls , and stair or elevator shafts can carry most of the horizontal forces . The problem is primarily one of shear resistance . Moderate addition bracing for rigid frames in“short”buildings can easily be provided by filling certain panels ( or even all panels ) without increasing the sizes of the columns and girders otherwise required for vertical loads.
Unfortunately , this is not is for high-rise buildings because the problem is primarily resistance to moment and deflection rather than shear alone . Special structural arrangements will often have to be made and additional structural material is always required for the columns , girders , walls , and slabs in order to made a high-rise
buildings sufficiently resistant to much higher lateral deformations .
As previously mentioned , the quantity of structural material required per square foot of floor of a high-rise buildings is in excess of that required for low-rise buildings . The vertical components carrying the gravity load , such as walls , columns , and shafts , will need to be strengthened over the full height of the buildings . But quantity of material required for resisting lateral forces is even more significant .
With reinforced concrete , the quantity of material also increases as the number of stories increases . But here it should be noted that the increase in the weight of material added for gravity load is much more sizable than steel , whereas for wind load the increase for lateral force resistance is not that much more since the weight of a concrete buildings helps to resist overturn . On the other hand , the problem of design for earthquake forces . Additional mass in the upper floors will give rise to a greater overall lateral force under the of seismic effects .
In the case of either concrete or steel design , there are certain basic principles for providing additional resistance to lateral to lateral forces and deflections in high-rise buildings without too much sacrifire in economy .
1.Increase the effective width of the moment-resisting subsystems . This is
very useful because increasing the width will cut down the overturn force
directly and will reduce deflection by the third power of the width increase ,
other things remaining cinstant . However , this does require that vertical
components of the widened subsystem be suitably connected to actually
gain this benefit.
2.Design subsystems such that the components are made to interact in the
most efficient manner . For example , use truss systems with chords and
diagonals efficiently stressed , place reinforcing for walls at critical
locations , and optimize stiffness ratios for rigid frames .
3.Increase the material in the most effective resisting components . For
example , materials added in the lower floors to the flanges of columns and
connecting girders will directly decrease the overall deflection and increase
the moment resistance without contributing mass in the upper floors where
the earthquake problem is aggravated .
4.Arrange to have the greater part of vertical loads be carried directly on the
primary moment-resisting components . This will help stabilize the
buildings against tensile overturning forces by precompressing the major
overturn-resisting components .
5.The local shear in each story can be best resisted by strategic placement if
solid walls or the use of diagonal members in a vertical subsystem .
Resisting these shears solely by vertical members in bending is usually less
economical , since achieving sufficient bending resistance in the columns
and connecting girders will require more material and construction energy
than using walls or diagonal members .
6.Sufficient horizontal diaphragm action should be provided floor . This will
help to bring the various resisting elements to work together instead of
separately .
7.Create mega-frames by joining large vertical and horizontal components
such as two or more elevator shafts at multistory intervals with a heavy
floor subsystems , or by use of very deep girder trusses .
Remember that all high-rise buildings are essentially vertical cantilevers which are supported at the ground . When the above principles are judiciously applied , structurally desirable schemes can be obtained by walls , cores , rigid frames, tubular construction , and other vertical subsystems to achieve horizontal strength and rigidity . Some of these applications will now be described in subsequent sections in the following .
Shear-Wall Systems
When shear walls are compatible with other functional requirements , they can be economically utilized to resist lateral forces in high-rise buildings . For example , apartment buildings naturally require many separation walls . When some of these are designed to be solid , they can act as shear walls to resist lateral forces and to carry the vertical load as well . For buildings up to some 20storise , the use of shear walls is common . If given sufficient length ,such walls can economically resist lateral forces up to 30 to 40 stories or more .
However , shear walls can resist lateral load only the plane of the walls ( i.e.not in a diretion perpendicular to them ) . There fore ,it is always necessary to provide shear walls in two perpendicular directions can be at least in sufficient orientation so that lateral force in any direction can be resisted . In addition , that wall layout should reflect consideration of any torsional effect .
In design progress , two or more shear walls can be connected to from L-shaped or channel-shaped subsystems . Indeed , internal shear walls can be connected to from a rectangular shaft that will resist lateral forces very efficiently . If all external shear walls are continuously connected , then the whole buildings acts as tube , and connected , then the whole buildings acts as a tube , and is excellent Shear-Wall Seystems resisting lateral loads and torsion .
Whereas concrete shear walls are generally of solid type with openings when necessary , steel shear walls are usually made of trusses . These trusses can have single diagonals , “X”diagonals , or“K”arr angements . A trussed wall will have its members act essentially in direct tension or compression under the action of view ,
and they offer some opportunity and deflection-limitation point of view , and they offer some opportunity for penetration between members . Of course , the inclined members of trusses must be suitable placed so as not to interfere with requirements for wiondows and for circulation service penetrations though these walls .
As stated above , the walls of elevator , staircase ,and utility shafts form natural tubes and are commonly employed to resist both vertical and lateral forces . Since these shafts are normally rectangular or circular in cross-section , they can offer an efficient means for resisting moments and shear in all directions due to tube structural action . But a problem in the design of these shafts is provided sufficient strength around door openings and other penetrations through these elements . For reinforced concrete construction , special steel reinforcements are placed around such opening .In steel construction , heavier and more rigid connections are required to resist racking at the openings .
In many high-rise buildings , a combination of walls and shafts can offer excellent resistance to lateral forces when they are suitably located ant connected to one another . It is also desirable that the stiffness offered these subsystems be more-or-less symmertrical in all directions .
Rigid-Frame Systems
In the design of architectural buildings , rigid-frame systems for resisting vertical and lateral loads have long been accepted as an important and standard means for designing building . They are employed for low-and medium means for designing buildings . They are employed for low- and medium up to high-rise building perhaps 70 or 100 stories high . When compared to shear-wall systems , these rigid frames both within and at the outside of a buildings . They also make use of the stiffness in beams and columns that are required for the buildings in any case , but the columns are made stronger when rigidly connected to resist the lateral as well as vertical forces though frame bending .
Frequently , rigid frames will not be as stiff as shear-wall construction , and therefore may produce excessive deflections for the more slender high-rise buildings designs . But because of this flexibility , they are often considered as being more ductile and thus less susceptible to catastrophic earthquake failure when compared with ( some ) shear-wall designs . For example , if over stressing occurs at certain portions of a steel rigid frame ( i.e.,near the joint ) , ductility will allow the structure as a whole to deflect a little more , but it will by no means collapse even under a much
larger force than expected on the structure . For this reason , rigid-frame construction is considered by some to be a “best”seismic-resisting type for high-rise steel buildings . On the other hand ,it is also unlikely that a well-designed share-wall system would collapse.
In the case of concrete rigid frames ,there is a divergence of opinion . It true that if a concrete rigid frame is designed in the conventional manner , without special care to produce higher ductility , it will not be able to withstand a catastrophic earthquake that can produce forces several times lerger than the code design earthquake forces . therefore , some believe that it may not have additional capacity possessed by steel rigid frames . But modern research and experience has indicated that concrete frames can be designed to be ductile , when sufficient stirrups and joinery reinforcement are designed in to the frame . Modern buildings codes have specifications for the so-called ductile concrete frames . However , at present , these codes often require excessive reinforcement at certain points in the frame so as to cause congestion and result in construction difficulties 。Even so , concrete frame design can be both effective and economical 。
Of course , it is also possible to combine rigid-frame construction with shear-wall systems in one buildings ，For example , the buildings geometry may be such that rigid frames can be used in one direction while shear walls may be used in the other direction。
Summary
Above states is the high-rise construction ordinariest structural style. In the design process, should the economy practical choose the reasonable form as far as possible.

高层建筑
前沿
高层建筑的定义很难确定。可以说2-3层的建筑物为底层建筑，而从3-4层地10层或20层的建筑物为中层建筑，高层建筑至少为10层或者更多。
尽管在原理上，高层建筑的竖向和水平构件的设计同低层及多层建筑的设计没什么区别，但使竖向构件的设计成为高层设计有两个控制性的因素：首先，高层建筑需要较大的柱体、墙体和井筒；更重要的是侧向里所产生的倾覆力矩和剪力变形要大的多，必要谨慎设计来保证。
高层建筑的竖向构件从上到下逐层对累积的重力和荷载进行传递，这就要有较大尺寸的墙体或者柱体来进行承载。同时，这些构件还要将风荷载及地震荷载等侧向荷载传给基础。但是，侧向荷载的分布不同于竖向荷载，它们是非线性的，并且沿着建筑物高度的增加而迅速地增加。例如，在其他条件都相同时，风荷载在建筑物底部引起的倾覆力矩随建筑物高度近似地成平方规律变化，而在顶部的侧向位移与其高度的四次方成正比。地震荷载的效应更为明显。
对于低层和多层建筑物设计只需考虑恒荷载和部分动荷载时，建筑物的柱、墙、楼梯或电梯等就自然能承受大部分水平力。所考虑的问题主要是抗剪问题。对于现代的钢架系统支撑设计，如无特殊承载需要，无需加大柱和梁的尺寸，而通过增加板就可以实现。
不幸的是，对于高层建筑首先要解决的不仅仅是抗剪问题，还有抵抗力矩和抵抗变形问题。高层建筑中的柱、梁、墙及板等经常需要采用特殊的结构布置和特殊的材料，以抵抗相当高的侧向荷载以及变形。
如前所述，在高层建筑中每平方英尺建筑面积结构材料的用量要高于低层建筑。支撑重力荷载的竖向构件，如墙、柱及井筒，在沿建筑物整个高度方向上都应予以加强。用于抵抗侧向荷载的材料要求更多。
对于钢筋混凝土建筑，虽着建筑物层数的增加，对材料的要求也随着增加。应当注意的是，因混凝土材料的质量增加而带来的建筑物自重增加，要比钢结构增加得多，而为抵抗风荷载的能力而增加的材料用量却不是呢么多，因为混凝土自身的重量可以抵抗倾覆力矩。不过不利的一面是混凝土建筑自重的增加，将会加大抗震设计的难度。在地震荷载作用下，顶部质量的增加将会使侧向荷载剧增。
无论对于混凝土结构设计，还是对于钢结构设计，下面这些基本的原则都有
助于在不需要增加太多成本的前提下增强建筑物抵抗侧向荷载的能力。
1.增加抗弯构件的有效宽度。由于当其他条件不变时能够直接减小扭
矩，并以宽度增量的三次幂形式减小变形，因此这一措施非常有效。
但是必须保证加宽后的竖向承重构件非常有效地连接。
2.在设计构件时，尽可能有效地使其加强相互作用力。例如，可以采用
具有有效应力状态的弦杆和桁架体系；也可在墙的关键位置加置钢
筋；以及最优化钢架的刚度比等措施。
3.增加最有效的抗弯构件的截面。例如，增加较低层柱以及连接大梁的
翼缘截面，将可直接减少侧向位移和增加抗弯能力，而不会加大上层
楼面的质量，否则，地震问题将更加严重。
4.通过设计使大部分竖向荷载，直接作用于主要的抗弯构件。这样通过
预压主要的抗倾覆构件，可以使建筑物在倾覆拉力的作用下保持稳
定。
5.通过合理地放置实心墙体及在竖向构件中使用斜撑构件，可以有效地
抵抗每层的局部剪力。但仅仅通过竖向构件进行抗剪是不经济的，因
为使柱及梁有足够的抗弯能力，比用墙或斜撑需要更多材料和施工工
作量。
6.每层应加设充足的水平隔板。这样就会使各种抗力构件更好地在一起
工作，而不是单独工作。
7.在中间转换层通过大型竖向和水平构件及重楼板形成大框架，或者采
用深梁体系。
应当注意的是，所有高层建筑的本质都是地面支撑的悬臂结构。如何合理地运用上面所提到的原则，就可以利用合理地布置墙体、核心筒、框架、筒式结构和其他竖向结构分体系，使建筑物取得足够的水平承载力和刚度。本文后面将对这些原理的应用做介绍。
剪力墙结构
在能够满足其他功能需求时，高层建筑中采用剪力墙可以经济地进行高层建筑的抗侧向荷载设计。例如，住宅楼需要很多隔墙，如果这些隔墙都设计为实例的，那么他们可以起到剪力墙的作用，既能抵抗侧向荷载，又能承受竖向荷载。对于20层以上的建筑物，剪力墙极为常见。如果给与足够的宽度，剪力墙能够有效地抵抗30-40层甚至更多的侧向荷载。
但是，剪力墙只能抵抗平行于墙平面的荷载（也就是说不能抵抗垂直于墙的荷载）。因此有必要经常在两个相互垂直的方向设置剪力墙，或者在尽可能多的方向布置，以用来抵抗各个方向的侧向荷载。并且，墙体设计还应考虑扭转的问题。
在设计过程中，两片或者更多的剪力墙会布置成L型或者槽形。实际上，四片内剪力墙可以被联结成矩形，以更有效地抵抗侧向荷载。如果所有外部剪力墙都连接起来，整个建筑物就像是一个筒体，将会具有很强的抵抗水平荷载和抵抗
扭矩的能力。
通常混凝土就剪力墙都是实体的，并在有要求时开洞，而钢筋剪力墙常常是做成桁架式。这些桁架上可能布置成蛋单斜撑、X斜撑及K斜撑。在侧向力作用下这些桁架的组合构件受到或拉或压力。从强度和变形控制角度来说，桁架有着很好的功效，并且管道可以在构件之间穿过。当然，钢桁架墙的斜向构件在墙体上要正确放置，以免妨碍开窗、循环以及管道穿墙。
如上所述，电梯强、楼梯间及设备竖井都可以形成筒状体，常常用它们既抵抗竖向荷载又抵抗水平荷载。这些筒的横断面一般驶矩形或圆形，由于筒结构作用，筒状结构能够有效地进行各个方向上的抗弯和抗剪。不过在这样的结构设计中存在的问题是，如何保证在门洞口和其他孔洞的强度。对于钢筋混凝土结构，通过使用特殊的钢筋配置在这些孔洞的周围。对于钢剪力墙，则要求在开洞处加强节点连接，以抵抗洞口变形。
对于很多高层建筑，如果墙体和筒架进行合理地安排与连接，会起到很好的抵抗侧向荷载的作用。还要求由这些结构分体系提供的刚度在各个方向上应大体对称。
框架结构
在建筑物结构设计中，用于抵抗竖向和水平荷载的框架结构，常作为一个重要且标准的型式而被采用。它适用于低层、多层建筑物，亦可用于70-100层高的高层建筑物。同剪力墙结构相比，这种结构更适合在建筑物的内部或者外围的墙体上开设矩形孔洞。同时它还能充分利用建筑物内在任何情况下都要采用的梁和柱的刚度，但当柱子与梁刚性连接时，通过框架受弯来抵抗水平和竖向荷载会使这些柱子的承载能力变得更大。
大多情况下，框架的刚度不如剪力墙，因此对于细长的建筑物将会出现过度变形。但正是因为其柔性，使得其与剪力墙结构相比具有更大的延性，因而地震荷载下不易发生事故。例如，如果框架局部出现超应力时，那么其延性就会允许整个结构出现倒塌事故。因此，框架结构常被视为最好的高层抗震结构。另一方面，设计得好的剪力墙结构也不可能倒塌。
对于混凝土框架结构，还存在较大的分歧。的确。如果在混凝土框架设计时不进行特殊的延性设计，那么他将很难承受比设计标准值大很多倍的地震荷载的冲击。因此，很多人认为它不具备钢框架所具备的超载能力。不过最新的研究i 和实验表明，当混凝土中放入充分的钢箍和节点钢筋时，混凝土框架框架也能表现出很好的延性。新建筑规范对所谓延性混凝土框架有专门的规定。然而，这些规范往往要求在框架的某处增设过多的钢筋，这就增加了施工的难度。尽管这
样，混凝土框架设计还是具备既经济又实用的特性。
当然，还可以在建筑结构设计中，将框架结构和剪力墙结构结合起来使用。例如，在房屋建筑上使用框架，而在另一方向上可以使用剪力墙。
结论
以上所述就是高层建筑最普通的结构形式。在设计过程中，应尽可能经济实用地选择合理的形式。
PA VEMENT PROBLEMS CAUSED BY COLLAPSIBLE SUBGRADES By Sandra L. Houston,1 Associate Member, ASCE (Reviewed by the Highway Division) ABSTRACT: Problem subgrade materials consisting of collapsible soils are com- mon in arid environments, which have climatic conditions and depositional and weathering processes favorable to their formation. Included herein is a discussion of predictive techniques that use commonly available laboratory equipment and testing methods for obtaining reliable estimates of the volume change for these problem soils. A method for predicting relevant stresses and corresponding collapse strains for typical pavement subgrades is presented. Relatively simple methods of evaluating potential volume change, based on results of familiar laboratory tests, are used. INTRODUCTION When a soil is given free access to water, it may decrease in volume, increase in volume, or do nothing. A soil that increases in volume is called a swelling or expansive soil, and a soil that decreases in volume is called a collapsible soil. The amount of volume change that occurs depends on the soil type and structure, the initial soil density, the imposed stress state, and the degree and extent of wetting. Subgrade materials comprised of soils that change volume upon wetting have caused distress to highways since the be- ginning of the professional practice and have cost many millions of dollars in roadway repairs. The prediction of the volume changes that may occur in the field is the first step in making an economic decision for dealing with these problem subgrade materials. Each project will have different design considerations, economic con- straints, and risk factors that will have to be taken into account. However, with a reliable method for making volume change predictions, the best design relative to the subgrade soils becomes a matter of economic comparison, and a much more rational design approach may be made. For example, typical techniques for dealing with expansive clays include: (1) In situ treatments with substances such as lime, cement, or fly-ash; (2) seepage barriers and/ or drainage systems; or (3) a computing of the serviceability loss and a mod- ification of the design to "accept" the anticipated expansion. In order to make the most economical decision, the amount of volume change (especially non- uniform volume change) must be accurately estimated, and the degree of road roughness evaluated from these data. Similarly, alternative design techniques are available for any roadway problem. The emphasis here will be placed on presenting economical and simple methods for: (1) Determining whether the subgrade materials are collapsible; and (2) estimating the amount of volume change that is likely to occur in the 'Asst.

开挖工程支撑体系的发展 1.引言 几乎所有土木工程建设项目（如建筑物，道路，隧道，桥梁，污水处理厂，管道，下水道）都涉及泥土挖掘的一些工程量。往往由于由相邻的结构，特性线，或使用权空间的限制，必须要一个土地固定系统，以允许土壤被挖掘到所需的深度。历史上，许多挖掘支撑系统已经开发出来。其中，现在比较常见的几种方法是：板桩，钻孔桩墙，泥浆墙。 土地固定系统的选择是由技术性能要求和施工可行性（例如手段，方法）决定的，包括执行的可靠性，而成本考虑了这些之后，其他问题也得到解决。通常环境后果（用于处理废泥浆和钻井液如监管要求）也非常被关注（邱阳、1998）。 土地固定系统通常是建设项目的较大的一个组成部分。如果不能按时完成项目，将极大地影响总成本。通常首先建造支撑，在许多情况下，临时支撑系统是用于支持在挖掘以允许进行不断施工，直到永久系统被构造。临时系统可以被去除或留在原处。 打桩时，因撞击或振动它们可能会被赶入到位。在一般情况下，振动是最昂贵的方法，但只适合于松散颗粒材料，土壤中具有较高电阻（例如，通过鹅卵石）的不能使用。采用打入桩系统通常是中间的成本和适合于软沉积物（包括粘性和非粘性），只要该矿床是免费的鹅卵石或更大的岩石。 通常，垂直元素（例如桩）的前安装挖掘工程和水平元件（如内部支撑或绑回）被安装为挖掘工程的进行下去，从而限制了跨距长度，以便减少在垂直开发弯矩元素。在填充情况下，桩可先设置，从在斜坡的底部其嵌入悬挑起来，安装作为填充进步水平元素（如搭背或土钉）。如果滞后是用来保持垂直元素之间的土壤中，它被安装为挖掘工程的进行下去，或之前以填补位置。 吉尔- 马丁等人（2010）提供了一个数值计算程序，以获取圆形桩承受轴向载荷和统一标志（如悬臂桩）的单轴弯矩的最佳纵筋。他们开发的两种优化流程：用一个或两个直径为纵向钢筋。优化增强模式允许大量减少的设计要求钢筋的用量，这些减少纵向钢筋可达到50％相对传统的，均匀分布的加固方案。 加固桩集中纵向钢筋最佳的位置在受拉区。除了节约钢筋，所述非对称加强钢筋图案提高抗弯刚度，通过增加转动惯量的转化部分的时刻。这种增加的刚性可能会在一段时间内增加的变形与蠕变相关的费用。评估相对于传统的非对称加强桩的优点，对称，钢筋桩被服务的条件下全面测试来完成的，这种试验是为了验证结构的可行性和取得的变形的原位测量。 基于现场试验中，用于优化的加强图案的优点浇铸钻出孔（CIDH）在巴塞罗那的

From the basic physiological needs gradually to meet the psychological and cultural fields of promoting a higher level, the residential area is not only the function of living, but also people's thinking and feelings of the local exchange. Therefore, the strengthening of exchanges between the residential areas of space construction, increase residential neighbourhood affinity, should be developed in the planning and construction of residential areas should also consider the issue. How to conduct exchanges between the residential areas of space planning and design, improve people's quality of life, the author of his own real estate development
项目成本控制 一、引言 项目是企业形象的窗口和效益的源泉。随着市场竞争日趋激烈，工程质量、文明施工要求不断提高，材料价格波动起伏，以及其他种种不确定因素的影响，使得项目运作处于较为严峻的环境之中。由此可见项目的成本控制是贯穿在工程建设自招投标阶段直到竣工验收的全过程，它是企业全面成本管理的重要环节，必须在组织和控制措施上给于高度的重视，以期达到提高企业经济效益的目的。 二、概述 工程施工项目成本控制，指在项目成本在成本发生和形成过程中，对生产经营所消耗的人力资源、物资资源和费用开支，进行指导、监督、调节和限制，及时预防、发现和纠正偏差从而把各项费用控制在计划成本的预定目标之内，以达到保证企业生产经营效益的目的。 三、施工企业成本控制原则 施工企业的成本控制是以施工项目成本控制为中心，施工项目成本控制原则是企业成本管理的基础和核心，施工企业项目经理部在对项目施工过程进行成本控制时，必须遵循以下基本原则。 3.1 成本最低化原则。施工项目成本控制的根本目的，在于通过成本管理的各种手段，促进不断降低施工项目成本，以达到可能实现最低的目标成本的要求。在实行成本最低化原则时，应注意降低成本的可能性和合理的成本最低化。一方面挖掘各种降低成本的能力，使可能性变为现实；另一方面要从实际出发，制定通过主观努力可能达到合理的最低成本水平。 3.2 全面成本控制原则。全面成本管理是全企业、全员和全过程的管理，亦称“三全”管理。项目成本的全员控制有一个系统的实质性内容，包括各部门、各单位的责任网络和班组经济核算等等，应防止成本控制人人有责，人人不管。项目成本的全过程控制要求成本控制工作要随着项目施工进展的各个阶段连续 进行，既不能疏漏，又不能时紧时松，应使施工项目成本自始至终置于有效的控制之下。 3.3 动态控制原则。施工项目是一次性的，成本控制应强调项目的中间控制，即动态控制。因为施工准备阶段的成本控制只是根据施工组织设计的具体内容确
building types and design A 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 ,the metallurgical industry ,machine building ,the chemical industry and the textile industry . factory buildings can be classified into two types single-story ones and multi-story ones .the construction of industrial buildings is the same as that of civil buildings .however ,industrial and civil buildings differ in the materials used and in the way they are used . Civil buildings are divided into two broad categories: residential buildings and public buildings .residential buildings should suit family life .each flat should consist of at least three necessary rooms : a living room ,a kitchen and a toilet .public buildings can be used in politics ,cultural activities ,administration work and other services ,such as schools, office buildings, parks ,hospitals ,shops ,stations ,theatres ,gymnasiums ,hotels ,exhibition halls ,bath pools ,and so on .all of them have different functions ,which in turn require different design types as well. Housing is the living quarters for human beings .the basic function of housing is to provide shelter from the elements ,but people today require much more that of their housing .a family moving into a new neighborhood will to know if the available housing meets its standards of safety ,health ,and comfort .a family will also ask how near the housing is to grain shops ,food markets ,schools ,stores ,the library ,a movie theater ,and the community center . In the mid-1960’s a most important value in housing was sufficient space both inside and out .a majority of families preferred single-family homes on about half an acre of land ,which would provide space for spare-time activities .in highly industrialized countries ,many families preferred to live as far out as possible from the center of a metropolitan area ,even if the wage earners had to travel some distance to 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.

附件1：外文资料翻译译文 抗侧向荷载的结构体系 常用的结构体系 若已测出荷载量达数千万磅重，那么在高层建筑设计中就没有多少可以进行极其复杂的构思余地了。确实，较好的高层建筑普遍具有构思简单、表现明晰的特点。 这并不是说没有进行宏观构思的余地。实际上，正是因为有了这种宏观的构思，新奇的高层建筑体系才得以发展，可能更重要的是：几年以前才出现的一些新概念在今天的技术中已经变得平常了。 如果忽略一些与建筑材料密切相关的概念不谈，高层建筑里最为常用的结构体系便可分为如下几类： 1.抗弯矩框架。 2.支撑框架，包括偏心支撑框架。 3.剪力墙，包括钢板剪力墙。 4.筒中框架。 5.筒中筒结构。 6.核心交互结构。 7. 框格体系或束筒体系。 特别是由于最近趋向于更复杂的建筑形式，同时也需要增加刚度以抵抗几力和地震力，大多数高层建筑都具有由框架、支撑构架、剪力墙和相关体系相结合而构成的体系。而且，就较高的建筑物而言，大多数都是由交互式构件组成三维陈列。 将这些构件结合起来的方法正是高层建筑设计方法的本质。其结合方式需要在考虑环境、功能和费用后再发展，以便提供促使建筑发展达到新高度的有效结构。这并
不是说富于想象力的结构设计就能够创造出伟大建筑。正相反，有许多例优美的建筑仅得到结构工程师适当的支持就被创造出来了，然而，如果没有天赋甚厚的建筑师的创造力的指导，那么，得以发展的就只能是好的结构，并非是伟大的建筑。无论如何，要想创造出高层建筑真正非凡的设计，两者都需要最好的。 虽然在文献中通常可以见到有关这七种体系的全面性讨论，但是在这里还值得进一步讨论。设计方法的本质贯穿于整个讨论。设计方法的本质贯穿于整个讨论中。 抗弯矩框架 抗弯矩框架也许是低，中高度的建筑中常用的体系，它具有线性水平构件和垂直构件在接头处基本刚接之特点。这种框架用作独立的体系，或者和其他体系结合起来使用，以便提供所需要水平荷载抵抗力。对于较高的高层建筑，可能会发现该本系不宜作为独立体系，这是因为在侧向力的作用下难以调动足够的刚度。 我们可以利用STRESS，STRUDL 或者其他大量合适的计算机程序进行结构分析。所谓的门架法分析或悬臂法分析在当今的技术中无一席之地，由于柱梁节点固有柔性，并且由于初步设计应该力求突出体系的弱点，所以在初析中使用框架的中心距尺寸设计是司空惯的。当然，在设计的后期阶段，实际地评价结点的变形很有必要。 支撑框架 支撑框架实际上刚度比抗弯矩框架强，在高层建筑中也得到更广泛的应用。这种体系以其结点处铰接或则接的线性水平构件、垂直构件和斜撑构件而具特色，它通常与其他体系共同用于较高的建筑，并且作为一种独立的体系用在低、中高度的建筑中。
7 Rigid-Frame Structures A rigid-frame high-rise structure typically comprises parallel or orthogonally arranged bents consisting of columns and girders with moment resistant joints. Resistance to horizontal loading is provided by the bending resistance of the columns, girders, and joints. The continuity of the frame also contributes to resisting gravity loading, by reducing the moments in the girders. The advantages of a rigid frame are the simplicity and convenience of its rectangular form.Its unobstructed arrangement, clear of bracing members and structural walls, allows freedom internally for the layout and externally for the fenestration. Rig id frames are considered economical for buildings of up to' about 25 stories, above which their drift resistance is costly to control. If, however, a rigid frame is combined with shear walls or cores, the resulting structure is very much stiffer so that its height potential may extend up to 50 stories or more. A flat plate structure is very similar to a rigid frame, but with slabs replacing the girders As with a rigid frame, horizontal and vertical loadings are resisted in a flat plate structure by the flexural continuity between the vertical and horizontal components. As highly redundant structures, rigid frames are designed initially on the basis of approximate analyses, after which more rigorous analyses and checks can be made. The procedure may typically inc lude the following stages: 1. Estimation of gravity load forces in girders and columns by approximate method. 2. Preliminary estimate of member sizes based on gravity load forces with arbitrary increase in sizes to allow for horizontal loading. 3. Approximate allocation of horizontal loading to bents and preliminary analysis of member forces in bents. 4. Check on drift and adjustment of member sizes if necessary. 5. Check on strength of members for worst combination of gravity and horizontal loading, and adjustment of member sizes if necessary. 6. Computer analysis of total structure for more accurate check on member strengths and drift, with further adjustment of sizes where required. This stage may include the second-order P-Delta effects of gravity loading on the member forces and drift.. 7. Detailed design of members and connections.
