earthquake fortification meaning in English
抗震设防
Examples
- The appropriate maximum stories and the appropriate maximum height of buildings are determined by using the various of control index , such as period , shear - compression ratio , allowable value of drift angle etc when earthquake fortification intensity is 8 degree
用各项控制指标，如周期、剪压比、轴压比、层间位移角等进行对比分析，给出在8度区该结构的最大可建造层数和最大适用高度。 - The deformation analysis was made to a 12 storey reinforcement concrete structure , building in site condition ii , earthquake fortification level 8 , by a program idarc - 2d which is put forward by the state university of new york at buffalo . the strong ground motion records obtained from pacific earthquake engineering research ( peer ) stiong ground motion database . thirty - eight waves were selected from the database by sorting the site condition and peak ground acceleration a comparison was made to the thirty - eight records " response spectra and the design response spectrum . thirteen waves were selected to the deformation analysis , el - centro wave and taft wave were added as a comparison . the result of computation shows that the selected waves damaged the structure severely than the el - centro wave and taft wave
利用idarc - 2d对一建于8度类场地上的12层钢筋混凝土框架结构进行了大震下的变形验算。强震记录取自加州国家地震中心强震数据库，按场地类别和峰值加速度对数据进行分类处理，从中选出38条波进行反应谱的拟合。最终选定拟合较好的13条波进行本次试算，作为比较加入了常用的el - centro波和taft波。 - Because of its many advantages , the tapered portal frame is getting more and more application . ( ( technology code of light steel structure of portal frame ) ) ( cecs 102 : 2002 ) , our country enacted , does n ' t define conditions that tapered portal frame needs anti - earthquak - e design . but mentions in illustration of rules : when earthquake fortification intensity is 7 degree , the portal frame does n ' t need anti - earthquake checking generally ; but for 8 degree and above , horizontal just with lengthways frames both need anti - earthquake checking
楔形变截面门式刚架山于其诸多的优点得到越来越广泛的应用，我国颁布的协会标准《门式刚架轻型房屋钢结构技术规程》 ( cecs102 2002 )中没有对变截面门式刚架需要进行抗震设计的情况进行具体规定，但在后面的条文说明中提到： “当抗震设防烈度为7度时，一般不需做抗震验算；当为8度及以上时，横向刚架和纵向框架均需做抗震验算。 ” - The earthquake fortification level and the seismic performance level of structure are introduced in the thesis ; in the push - over method and quasi - static test analysis , basic concepts , development histories , the present state and their future of development ; several computing methods of structure damage and judging the grade of structure damage are simply introduced
介绍了包括地震设防水准、结构抗震性能水准等基本概念；介绍了静力弹塑性分析方法( push - over方法)和拟静力循环往复加载分析方法的概念、发展历史、现状与研究前景；并简要阐述了计算结构损伤和判断结构损伤等级的一些方法。
