摘要：本文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。

Abstract: 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 capacity 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.
