【摘要】 本文基于结构随机振动理论,考虑土-结构间的动力相互作用,对框架结构、框剪结构和筒体结构等三种不同结构体系的随机地震反应问题进行了计算,探讨了土-结构相互作用因素对上述三种不同结构体系随机地震反应的影响,分析了三种不同结构体系在位移功率谱响应、加速度功率谱响应和位移方差响应的差异。更多还原

【Abstract】 Based on the structural random vibration theory and three-dimensional finite element method, random seismic responses of three different type of structural systems have been analysed taking into account the soil-structure interaction. According the calculating results, statistic behavior of the maximal random seismic responses for stuctures under differnet seismic exitations is investigated.更多还原
