抗震分析反应谱法和时程分析法数值仿真比较

A Numerical Simulation Comparison between Response Spectrum Analysis and Time History Analysis

基于ANSYS有限元软件比较抗震分析反应谱法和时程分析法的地震数值仿真结果,研究二者的共同性和仿真结果的可比较性。结果表明,反应谱法和时程分析法在抗震反应计算中都体现了地震动特性和结构动态特性对结构地震响应的影响,二者在响应最值和响应频率上的仿真结果具有一致性。

Based on ANSYS FEM software,the simulation results of response spectrum analysis method and time history analysis method are compared.The concurrence of tow methods and comparability of the results are studied.The result shows that the influences of characteristics of ground motion and the structure dynamic characteristics on earthquake response are taken into account in the calculation processes of both methods,and the calculation results of the earthquake response peak values and the main response frequencies are consistent.
