| 摘 要： | 文章对静力弹塑性分析(push-over方法)的基本原理及实现步骤进行了简要的介绍;应用大型有限元软件MIDAS/GEN 空间结构程序对一个21层框架-剪力墙结构进行了静力弹塑性分析和抗震性能评价;结果表明,该方法可从层间位移角、塑性铰分布及变形等方面对结构进行综合的量化评价,并能揭示出结构在罕遇地震作用下的薄弱环节,是实现基于性能设计的有效方法.

| Abstract: | This paper presents the principle and calculation procedures of the method in MIDAS/GEN.A frame-shear-wall structure is analyzed and the result proves that the push-over method is effective in performance-based design since it can not only give a general assessment of the structure with regard to many points such as the plastic hinge distribution,the inelastic displacement of stories,but it can also reveal the weak points of the structure under the action of earthquakes that seldom occur. |
