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 finite element software SAP2000 is used to calculate the seismic resistance of Wenchuan earthquake-damaged telecom building. At the same time, three kinds of seismic calculation methods, ie, bottom shear method, mode decomposition response spectrum method and time history analysis method are compared and studied, The characteristics and scope of application. By observing the displacement between structural layers, the change of internal forces and the vibration animation process, we can get a more intuitive understanding and deeper understanding of seismic calculation.
