摘要
为了满足工程研究的需要,而现有的地震记录在数量上又不满足要求,这就要求人们根据地震动的特性来模拟合成地震动。合成地震动的研究经过几十年的探索也取得了长足进步,综合考虑到震源物理过程,传播过程以及场地条件的模拟,结合工程实际进行目标反应谱的拟和。介绍了一些合成地震动的方法,对当今以及今后合成地震动的研究方向给出一个综述。
Currently,no enough seismic records are obtained,in order to serve for the research of seismic project,so artificial ground motions are required based on the characteristic of ground motion as supplement.After development of several decades of years,the research on the artificial ground motions has made great progress.Considering the influential factors such as seismic source,propagation and site,the object response spectra are simulated with combining the engineering project.This essay introduces some meth...
