building types and designA building is closely bound up with people，for it provides with the necessary space to work and live in .As classified by their use ,buildings are mainly of two types :industrial buildings and civil buildings .industrial buildings are used by various factories or industrial production while civil buildings are those that are used by people 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 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 dining alcove .the “night “rooms consist of the bedrooms .the “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 .翻译：建筑类型和设计建筑物与人们有着紧密的联系，他为人们提供必要的空间，用以工作和生活。根据适用类型不同，建筑物可以分为两类：工业建筑和民用建筑。工业建筑包括各个工厂或工业生产所使用建筑，民用建筑是指那些人们用以居住，就业，教育和其他社会活动的建筑场所。工业建筑的厂房可用于采矿业，冶金工业，机械制造，化学工业和纺织工业等各类领域的加工和制造。厂房可分为两种类型：单层的和多层的。工业建筑也属于建筑的一种。但是，工业建筑与民用建筑所用的材料和建筑方式不同。民用建筑按使用可分为两大类：住宅建筑和公共建筑。住宅建筑要适应家庭生活。每个单位应包括至少三个必要客房：起居室，厨房和厕所。公共建筑可在政治，文化活动，管理工作和其他服务，如学校，写字楼，公园，医院，商店，车站，剧院，体育馆，宾馆，展览馆，洗浴池，等等。他们都有着不同的职能，这反过来又需要不同的设计类型。房屋是用以住人的. 其基本功能是提供住房的内容，但今天人们需要更多的住房内容。一个家庭在进入一个新的社区后将知道，现有住房不仅要符合其安全，健康和舒适等标准。还要考虑其附近是否有相应的配套设施，如食品市场，学校，商店，图书馆，电影院，以及社区中心等。在60年代中期住房最重要的价值是足够大的空间和方便的出入交通。大多数家庭会首选约半英亩面积土地的家庭住宅，这样将提供足够的空间的用以业余活动。在高度工业化的国家，许多家庭的首选是那种尽可能远离市中心商业圈的住房，即使距离上班地点不得不有一段距离。相当多的家庭首选是郊区的住房，因为他们的主要目的是要远离噪音，拥挤和混乱。拥有方便的公共交通使得距离不再是一个决定性因素，因为大多数人都是开着自己的汽车去上班了。人们现在主要感兴趣的是户型，房间的大小和卧室的数目。在工程项目开始之前，要做好建筑设计和施工流程,让人提前知道该建筑建成后是什么样子以及下一步应该做什么。在建筑设计中要特别重视房间的布局，其目的是提供最大的便利与可能的用途。在一个住宅建筑设计中，布局可考虑以下三个方面： “白天” ， “夜晚”和“服务”。必须注意这些空间区域之间的连通交流。 “白天”房一般包括餐厅，起居室和厨房，但其他房间可能会增加，如书房，并有可能成为一个大厅。起居室通常是最大的，往往是一个餐厅，也或可能有厨房、凹室等。 “夜间”房间包括卧室、客房。“服务”用房间包括厨房，浴室，储藏室 ，和厕所等。厨房和储藏室需设置在一起，以方便其房间功能的使用。此外，还必须考虑各种客房的朝向问题，当然最好尽可能的将那些经常使用的房间朝南设置。然而，在考虑到周围的环境和地点、道路等多方面因素，往往很难达到最佳要求。在解决这些复杂的问题，还必须按照当地城市规划条例所涉及的对公共设施，人口密度，建筑物高度，绿化面积，建筑红线等的要求，还要考虑到有相邻建筑的情况，等等。尽管工业建筑需要符合当地城市规划条例但很少有标准化的工业楼宇。现代厂房建筑的趋势是轻质、通风。一般的钢筋混凝土结构或钢结构的工厂，可以得到一个“跌”型脊屋顶，把窗户开向北以便使分布均匀的自然采光不会直射进来造成刺眼。

我也是土木专业的，把以前我用的那个发给你参考一下。去看邮箱吧。

[外文原文] Bridge Introduction The simplest type of span is a beam bridge, consisting of a rigid beam between two supports. Today most simple beam bridges are strengthened by a truss, which is based on the triangle. Diagonal beams that extend between the horizontal and vertical beams give support against both compression and tension. Many early truss bridges were built of wood; one that was erected across the Susquehanna River in Pennsylvania in 1815 had a span of 110 meters. Iron and then steel were later used in the construction of truss bridges, still further increasing their strength. Trusses are not only strong but also light, because all unnecessary materials have been eliminated in their designs. Another type of beam bridge is the cantilever, in which a horizontal beam extends beyond its support. Cantilever bridges, like trusses, had also been built before iron and steel became available. Most cantilever bridges have two arms of truss structure that meet or support a section between them. Cantilevers enabled bridge builder to span longer distances than truss bridges. During the nineteenth century, cantilevers were frequently used to build railroad bridges. The QuebecBridge, which crosses the St. Lawrence River in Canada, is the longest cantilever bridge in the world, with a span of 540 meters. It was completed in 1917, and until 1929 it was the longest bridge of all the types in the world. [外文翻译] 桥梁简介 在两个支座间架上刚性梁组成的梁桥是最简单的桥孔结构。现在，最简单的梁桥是用以三角形为基础的桁架加固的。连接于横梁和竖梁之间的斜梁既加强了抗压能力，又加强了抗拉能力，许多早期的桁架桥是用木头建成，其中有一座建于1815年，横跨宾夕尼亚州萨斯奎哈纳河的跨度是110m。铁及其以后的钢是后来才用于建造桁架桥的，使它们的强度又进一步得到提高。桁架不仅坚固而且很轻，因为在其设计中已将所有不必要的材料去掉了。 另一种梁桥是悬臂桥，其横梁伸出于支座之外，和桁架一样，悬臂桥也是在使用铁和钢之前就已建造起来了。大多数悬臂梁桥有两个桁架式结构的臂，两个臂相交或支承着在它们之间的一个部件。悬臂使桥梁建造者们得以建造出跨度大于桁架桥的桥梁，在十九世纪，悬臂梁常常用于建造铁路桥。横跨加拿大圣劳伦斯河的魁北克桥，是世界上最长的一座悬臂桥，其跨度为540m。该桥建成于1917年，直到1929年魁北克桥桥仍是世界上各类型桥梁中最长的一座。 现代的第三种类型是钢拱桥，在其钢梁拱的上面或下面可架设车行道。拱产生强大的下推力及斜推力，因此，支承钢拱桥的桥墩须特别坚固。澳大利亚的悉尼港桥可能是最著名的钢拱桥了，其跨度是495m。新泽西和纽约的斯塔腾岛之间的贝莱桥的跨度还要长一米。 悬索桥可比其它各种桥梁跨过更长的距离。纽约的维拉察诺海峡桥是各种桥梁中最长的，有1280m的跨度，悬索桥桥面或车行道，用钢索悬吊，钢索锚固在结实的桥塔上，第一批现代化悬索桥用的是锻铁链。其中有些用了许多年，如在匈牙利的布达佩斯，横跨多瑙河的悬索桥即为一例。这座桥建成于1849年，大约在一百年之后，于第二次世界在战期间被破坏。
