摘　　要：采用非线性Hertz-damp碰撞模型,推导了滑移隔震结构(P-F和R-FBI)考虑相邻建筑物碰撞的动力方程,研究了碰撞对隔震结构和相邻建筑物的影响,并进行参数分析。分析结果表明:碰撞对基础滑移隔震结构的地震响应有明显的放大效应,在一定范围内,防震缝宽度、摩擦系数以及碰撞刚度对结构的碰撞反应有着显著的影响。Based on the nonlinear Hertz-damp collision model,dynamic equations of the sliding isolation structure(PF and R-FBI)in consideration of adjacent buildings is deduced,impact of the collision on the isolated structure and adjacent buildings is studied,and parameters of simulation is analyzed.The results show that the impact of the collision on seismic response of the base sliding structure has obvious amplification effect,the width of seismic joint,coefficient of friction,and collision rigidity has significant effects.
