采用不同的碰撞模型,研究了摩擦型隔震结构(P-F、R-FBI和FPS)在近断层地震作用下与限位装置相碰撞的动态反应特性,给出了不同碰撞的数学表达式以及各模型中参数的具体数值;研究发现,地震中隔震结构若发生碰撞将大大增加结构的层间剪力和加速度反应,且激起结构的高阶振型;不同碰撞模型的计算结果相差在10%以内,但非线性碰撞模型花费的计算时间长,因此在实际工程中采用线性的Kelvin模型精度已足够;上部结构的非线性对碰撞反应有很大影响,碰撞时非线性结构的底层最大剪力较线性结构有很大减小,且层间存在很大的残余位移;同时还研究了基底预留宽度以及上部结构的自振周期对隔震结构碰撞反应的影响;最后提出了加设高阻尼橡胶缓冲器减小隔震结构碰撞反应的防护措施。
