摘　　要：在满足小震不坏的前提下,利用Midas Gen对一框架剪力墙结构进行静力弹塑性Pushover分析,采用能力谱法得到能力谱曲线与需求谱曲线的交点(即性能点),评估结构在罕遇地震作用下能否满足预先设定的目标性能,并探讨高阶振型对高层结构的影响.In the precondition of surviving minor earthquakes ,pushover analysis on a high-level architecture structure based on Midas Gen Modal was carried out in the consideration of the impact of higher modes. The intersection （that is performance point） of the capac- ity spectrum and the demand spectrum was obtained. Then the abilities of the structures to satisfy the intended goals under the rarely - occurred earthquakes were evaluated, and the influence of higher modes on high-rise structure was investigated.

关 键 词：框架-剪力墙 PUSHOVER分析 模态分析
