摘　　要：以某多层钢筋混凝土框架结构及其隔震层为研究对象,设计了具有总相同水平刚度的使用摩擦摆支座(FPB)为主的隔震层及使用铅芯橡胶支座(LRB)配合滑动支座(SLD)的混合隔震层,对原结构进行了基础隔震设计,并进行了8度小震及大震下的非线性时程分析。分析结果表明:基础隔震对结构的层间位移角、楼面加速度、层间剪力有较好的控制作用。This paper studied a multi-storied RC frame structure and its isolation layer.A isolation layer mainly composed of FPB and another composed of LRB and SLD with the same vertical bearing capacity and total horizontal stiffness were designed and were used in the base isolation design of the frame structure,and the nonlinear time-history analysis under 8 degree frequent earthquake and major earthquake was made to verify the effects.The result shows that：base isolation has a mitigation effect on the interstory drift ratio,story acceleration and interstory shear force.
