| 摘 要： | 以一榀具有集中塑性铰单元模型的基础隔震钢框架为模型,分别采用静力弹塑性分析方法（Push-over）和直接积分的动力弹塑性时程的方法,基于过程追踪,计算了隔震框架各损伤模式首次出现时的层间位移、隔震层位移及框架顶点位移,对比研究了基础隔震结构在地震作用下的损伤.结果表明：Push-over静力弹塑性分析方法可以作为基础...

| Abstract: | Two methods,nonlinear static procedure(Push-over analysis) and nonlinear dynamic procedure,are used to analyze the ultimate plastic damage and the performance-point plastic damage of a 6-floor based-isolated-steel frame under severe earthquake action,based on process tracking.The story drift,the displacement of isolated floor,and the top-point displacement of structure are analyzed.The results reveal that push-over analysis can be considered as an effective and simple appraisal method about isolated structu... |
