摘要

对一并联复合隔震结构模型进行了振动台试验研究,通过逐渐增加摩擦滑板的数量来调整隔震层摩擦承压比的大小。分析了复合隔震体系不同摩擦承压比对隔震层滞回特性、基底剪力系数以及复合隔震体系非线性性能的影响。试验结果表明:复合隔震结构的非线性特性与摩擦承压比的大小及地震烈度大小有关,在合理的摩擦承压比取值范围内复合隔震结构具有良好的隔震性能。
A modle of parallel composite isolation,which the friction pressure ratio of isotation is changed by increasing the number of friction skateboarding,is tested to simulate the earthquake on shaking table in this paper.The influences of the hysteresis characeeristics,basal shear coefficient and the nonlinear properties of composite isolation system in different friction pressure ratio are analyzed.Experiment results show: the nonlinear properties of composite isolation system depend on friction pressure ratio and earthquake fore,and composite isolation system can provide good isolation performance in reasonable friction pressure ratio.
