为了解下列问题进行了统计研究:(i)受相同统计特性产生的人工地震波的结构其反应谱的变化;(ii)人工地震强震持续时间对结构反应的影响;(iii)在地震区进行反应的时程分析需要的地震波数量。研究结果表明柔性结构对众多具有同一统计特性的地震波 Statistical studies were conducted in order to solve the following problems: (i) changes in the response spectrum of the artificial seismic waves generated by the same statistical properties; (ii) the influence of the duration of strong earthquakes on the structural response of the artificial earthquakes; (iii) performed in the seismic zone The time-course analysis of the response requires the number of seismic waves. The results show that the flexible structure has many seismic waves with the same statistical characteristics
