6、贝色麦转炉法的推广。Gustave,Eiffel在法国率先使用了钢结构。他为1889年巴黎博览设计的机械馆和铁塔展现了钢结构的轻巧。埃菲尔铁塔高984英尺（300米），是当时最高的建筑，直到40年后，才被美国的一系列摩天大楼超过了它的高度。,Alexandre,Gustave,Eiffel,(18321923,),was,a,French,engineer,and,architect,and,a,specialist,of,metallic,structures.,He,is,famous,for,designing,the,Eiffel,Tower,built,for,the,1889,Un

25、,trs,桁架；lateral,stability：侧向稳定性；,而后，人们摩天大楼的结构形式，有了不同的看法，又回归到采用墙承重。1962年，由Eero,Saarinen设计的在纽约建成的哥伦比亚广播大厦，5英尺宽、间距为10英尺的混凝土柱子构成了一个环形墙。这种环形墙实际上组成了一个承重墙。产生这种趋势，是因为将建筑的墙体作为一个筒体，其刚度可以非常经济地抵抗风荷载。世贸大厦是另一个采用这种方式的例子。相比之下，刚架或者垂直桁架常用来保证侧向稳定性。,Eero,Saarinen(沙里宁,)：,(August,20,1910,in,Kirkkonummi,Finland,September,

30、玻璃、塑料还有铝等。木材是重要的房屋建筑材料，由于火灾危险很少用于商业、工业或公共建筑中。,Floors.,The,construction,of,the,floors,in,a,building,depends,on,the,basic,structural,frame,that,is,used.,In,steel,skeleton,construction,floors,are,either,slabs,of,concrete,resting,on,steel,beams,or,a,deck,consisting,of,corrugated,steel,with,a,concrete,to

33、板。楼板结构取决于结构的形式。在钢结构中，楼板是支撑在钢梁上的混凝土板，或者是波纹钢板加混凝土面层的楼板。在混凝土结构中，楼板是支撑在混凝土梁上的混凝土板，或者是一系列排列紧密的双向梁（肋）加上部的混凝土薄板，板下面呈格状。,girderpost,poured,concreteprofiled,steel,sheet,secondary,beam,composite,floor,with,profiled,steel,sheetIn,an,apartment,building,for,instance,where,walls,and,columns,are,spaced,at,12,to,18

42、为可能，并且可以允许创新，例如在结构的跨度方面。,Soils,and,Foundations.,All,buildings,are,supported,on,the,ground,and,therefore,the,nature,of,the,soil,becomes,an,extremely,important,consideration,in,the,design,of,any,building.,The,design,of,a,foundation,depends,on,many,soil,factors,such,as,type,of,soil,soil,stratification,

43、thickness,of,soil,layers,and,their,compaction,and,groundwater,conditions.,Soils,rarely,have,a,single,composition;,they,generally,are,mixtures,in,layers,of,varying,thickness.,For,evaluation,soils,are,graded,according,to,particle,size,which,increased,from,silt,to,clay,to,sand,to,gravel,to,rock.,In,gen

45、n,：分层；silt,：淤泥，粉土；square,skw,：平方；metric,metrik,：公制的,米制的；compaction,kmpkn,：压缩；,土壤和地基。所有建筑都是坐落在地面上的。因此任何设计中，土壤的特性成为一项的重要考虑环节。基础设计必须考虑众多因素，例如土壤类型、土壤分层、每层的厚度及压缩性、地下水状况等。土壤很少是单一成分的，通常是不同厚度土层的混合物。为了评估土壤，根据粒径不同，土壤依次划分为粉土、粘土、沙土、碎石土和岩石。通常，大粒径的土壤可以承受更大的荷载。最硬的岩石其负载可以高达每平方英尺100吨（976.5t/m2），但是柔软的粉土就只有每平方英尺0.25吨（

46、2.44t/m2）。All,soils,beneath,the,surface,are,in,a,state,of,compaction;,that,is,they,are,under,a,pressure,that,is,equal,to,the,weight,of,the,soil,column,above,it.,Many,soils(except,for,most,sands,and,gavels),exhibit,elastic,properties,-they,deform,when,compressed,under,load,and,rebound,when,the,load,i

47、s,removed.,The,elasticity,of,soils,is,often,time-dependent,that,is,deformations,of,the,soil,occur,over,a,length,of,time,which,may,vary,from,minutes,to,years,after,a,load,is,imposed.,Over,a,period,of,time,a,building,may,settle,if,it,imposes,a,load,on,the,soil,greater,than,the,natural,compaction,weigh

49、:时间依赖，时间性的；rebound:,ribaund,弹回；Impose,impuz,：施加；settle,：沉降；heave,hi:v,：举起；squeeze,skwi:z,：压缩所有地表下的土都处于受压状态，就是说，这些土承受与其上的土柱重量相等的压力。许多土（除了大多数沙土和碎石土）显示出弹性性质受压时会变形，卸载后恢复。土壤的弹性是有时间性的，也就是说，土的变形可能发生在荷载作用后从数分钟到数年的时间长度上。如果建筑物作用在土体上的荷载高于土的天然压实重量，可能产生沉降。相反，如果建筑物作用在土体上的荷载小于土的天然压实重量，建筑物就会被举起。土壤可能在建筑的重量下产生流动，就是说，

50、它很容易被压挤出。,Due,to,both,the,compaction,and,flow,effects,building,tend,to,settle.,Uneven,settlements,exemplified,by,the,leaning,towers,in,Pisa,and,Bologna,can,have,damaging,effects-the,building,may,lean,walls,and,partitions,may,crack,windows,and,doors,may,become,inoperative,and,in,the,extreme,a,buildin
