摘　　要：在建立了基础隔震结构动力反应方程的基础之上,通过数值模拟,对纯摩擦滑移隔震结构体系的地震反应进行了计算和分析,研究了该体系中摩擦因数的变化对隔震效果的影响。结果表明:当摩擦因数取较小值时,各楼层的加速度和层间剪力较小,隔震效果良好;反之,则隔震效果不佳。Pure sliding friction and seismic response of structural system were calculated and analyzed by numerical simulation based on dynamic response equations of base-isolated structures.The effect of friction coefficient on the isolation was discussed.The results showed that when the friction coefficient is of small value,the acceleration of each floor and the shear force between them are small,and isolation is good.On the contrary,the isolation is ineffective.
