| 中文摘要: |
| 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。 |
| 英文摘要: |
| The Midas finite element model is established for the engineering example, the model is analyzed by two kinds of calculation methods which are response spectrum and Pushover analysis, the earthquake seismic performance of the model is analysised under the rare earthquake and frequent earthquake, a comparative study was conducted on the calculation results. Use the static pushover curve to seek the performance point under the Pushover analysis of the structure , analysis on the appearance of plastic hinges at this moment. At the same time, the comparative analysis of the floor displacement, inter story displacement, story drift angle etc in this two cases, the above could explain the model can be very good response under the action of earthquake etc. |
