利用随机等效线性化方法 ,本文分析了地震激励下多层隔震建筑结构的动力响应。文中采用的地震波为过滤高斯白噪声 ,上部结构及叠层橡胶隔震器为线弹性 ,铅阻尼器为双线性恢复力模型。对隔震系统线性化后 ,推导了隔震结构的相对位移及绝对加速度的响应统计表达式 ,并通过算例讨论了地震波输入功率谱密度及场地卓越频率对结构响应的影响 Using stochastic equivalent linearization method, this paper analyzes the dynamic response of multi-storeyed building under seismic excitation. The seismic wave used in this paper is Gaussian white noise filter, the upper structure and laminated rubber isolator are linear elastic, and the lead damper is a bilinear restoring force model. After linearization of the isolation system, the statistical expressions of the relative displacements and the absolute accelerations of the isolated structure are deduced. The effects of the input PSD of the seismic waves and the frequency of the site on the structural response are discussed
