The parameters of random model of ground motion given in this study provide relatively reliable and accurate earthquake motion input for stochastic seismic response analysis of structures.
最后给出了规范各种工况下的地面加速度功率谱参数值，为随机抗震计算分析提供了依据。
When the stochastic seismic response of the structures is studied, lots of the earthquake records fit for the selected site are necessary to be used for initial data for structure model analysis.
在研究结构的随机地震反应时，要用大量的符合场地条件的地震记录作为输入数据。
