对按设计反应谱计算结构地震反应的建设

A PROP0SAL FOR IMPROVING THE CALCULATION PROCEDURE OF SEISMIC RESPONSE OF STRUCTURES BY EMPLOYING THE RESPONSE SPECTRUM METHOD

本文对我国现行抗震规范中结构地震反应的计算方法提出了改进意见。对按设计反应谱计算过程的详细分析表明:所建议的直接确定结构位移的公式,避免了由地震力求解位移反应的过程,因而可节约大量计算工作量。理论分析和实例计算表明,所建议的方法十分简便,其结果与规范方法完全一致。

A simple formula for calculating the displacement responses in seismicanalysis by the response spectrum method is presented in this paper.The proposed formula can greatly reduce the amount of calculation andyields exactly the same results as obtained with the method specified bythe current seismic design codes.
