摘要
结构抗震性能化设计已在我国"超限高层建筑工程"的抗震设计中得到广泛应用,其中弹塑性时程分析方法是实现抗震性能化设计的主要途径.结合工程实例,利用PERFORM-3D软件建立了某超高层钢筋混凝土结构的弹塑性模型.基于ATC-40,FEMA-356规范,结合我国规范定义的性能目标,对关键构件和耗能构件的抗震性能进行了评估,得到整体结构响应、构件的变形及结构能量耗散情况,可用于研究按我国现行规范设计的超高层混凝土结构在罕遇地震作用下的受力特点.
the performance-based seismic design method has been widely used in structural seismic de -sign of Ultra-limit High Rise Structures , mostly by processing elasto -plastic time-history analysis .Combi-ning with an engineering example , an elasto-plastic model of one super high -rise RC building was built by PERFORM-3D.The results of the whole structure response , component deformation and energy dissipation were achieved for assessing the performance of key and energy -dissipating components , based on ATC-40 ,FE-MA356 and Chinese Code .This paper can be used for the research of the elasto -plastic deformation and stress characteristics of the super high -rise building structure designed according to current codes under rare earth-quake .
