摘　　要：结合工程实例建立MIDAS有限元模型,分别对模型进行反应谱和Pushover这两种计算方法分析,分析其在大震下和多遇地震下的抗震性能,对计算结果进行对比研究。利用结构在Pushover分析下得到的静力弹塑性曲线求取性能点,分析此时刻的塑性铰出现情况。同时,对两种情况下的楼层位移、层间位移、层间位移角等进行对比分析,说明该模型能很好的响应地震作用下的反应等。The Midas finite element model is established for the engineering example ,we analyzed two kinds of calculation methods which are response spectrum and Pushover analysis .The earthquake seismic performance of the model is analyzed under the rare earthquake and frequent earthquake ,and compared with the results of the study .From the static pushover curve ,we seek the performance point under the Pushover analysis of the structure ,and analyze on the appearance of plastic hinges at this moment .At the same time ,we compared the floor displacement ,inter story displacement ,story drift angle etc in this two cases , to explain the model can be very good response the action of earthquake .

关 键 词：反应谱分析 模型 对比分析
