摘　　要：本文着重讨论具有叠层橡胶支座（ＬＲＢ）基础隔震系统的多层建筑的动力响应。文中采用常用的层间剪切模型，引入退化迟滞理论分析叠层橡胶隔震器的滞回特性曲线，进而分析了具有这种类型基础隔震系统的多层建筑的地震响应，探讨了隔震系统参数对结构响应的影响。This paper studies the dynamic responses of a base-isolated multi-storey building with laminated rubber bearings, in which the structure has been idealized as a shear-type multimass system. The hysteresis curve of the laminated rubber isolator has been analyzed with degenerated-hysteresis theory. The vibration responses of a multi-storey building with this type of isolation system have been calculated, and the influence of the parameters of the isolation system on structural responses is then reported.
