摘  要：在地震高烈度区，相比于传统抗震结构，隔震结构拥有更优异的抗震性能。为了探究传统隔震体系、单一隔震体系以及复合隔震体系对于结构动力特性的影响，采用不同的连接单元模拟传统支座，橡胶隔震支座以及摩擦滑移隔震支座,建立了基于SAP2000的三个等效模型，并对其进行了模态分析、反应谱分析和非线性时程分析。结果表明，隔震支座的使用以及多种隔震支座的合理布置对于结构的自振周期有明显的提高，对于结构受到的层间剪力有着明显的削弱，结构受到地震波的加速度反应也有很大程度的降低。

Abstract: Compared to traditional anti-seismic structure, the isolation structure has more excellent seismic performance. In order to study the structural dynamic influence of traditional isolation system, single isolation system and the composite isolation system, different connection unit of simulate traditional bearings, lead-rubber bearings and friction sliding bearings are used to establish three equivalent models based on SAP2000 and conducts modal analysis, response spectrum analysis and nonlinear time history analysis. The result shows that the use of isolation bearings and a variety of isolation bearings of reasonable arrangement will obviously increase the period of structure, weaken the structure interlayer shear of structure and greatly reduce the seismic acceleration response of structure.
