使用 SAP2000对存在薄弱层的高层钢结构进行了 PUSHOVER 分析，结果表明在多遇地震作用下即使柱应力比较小，并且弹性层间位移角也满足规范要求，但在罕遇地震作用下其薄弱层弹塑性层间位移角仍有可能超出规范要求，同时还讨论了增强薄弱层抗侧刚度的方法，分析了不同场地类别对结构地震响应的影响。

In this paper,SAP2000 is used for PUSHOVER analysis of the high rise steel structure where weak story exists. The results have showed that even if the stress ratio of column is small and the elastic deformation angle meets the code requirement in the case of frequently oc-curred earthquake,the elastic-plastic deformation angle may not meet the code requirement in the case of rarely occurred earthquake. This paper also discusses the strengthening method for weak story and analyses the variation of the earthquake effect due to different sites.
