摘要

应用有限元软件SAP2000对汶川地震什邡受损电信大楼进行抗震计算,同时对3种抗震计算方法,即底部剪力法、振型分解反应谱法、时程分析法进行比较研究,总结出其各自的特点和适用范围。通过观察结构层间位移、内力的变化以及振动动画过程,可对抗震计算有更加直观的认识与深入的理解。
The seismic calculation of the damaged telecom building in Shifang under 5.12 earthquake is carried out by finite element soft SAP2000,then three seismic calculation methods are compared,such as equivalent base shear method,mode analysis method and time-history method.The equivalent base shear method is the most simple,which can be the method of estimation and approximate treatment in the preliminary design phase.The mode analysis method is the main method,which can calculate the high-rise buildings,and the time-history method is a compensation method,which can calculate the complex high-rise building.At last the characters and the scope of application of above three methods are summarized.According to the changes of the storey drift,force and seismic animation,the intuitive and in-depth understanding could be derived.
