| 摘 要： | 采用Kelvin碰撞模型,推导了在近断层地震作用下隔震结构与相邻建筑物相碰撞的动力方程,研究了碰撞时隔震支座的隔震效果.并将隔震建筑与限位装置、与相邻非隔震结构以及与相邻隔震结构在近断层地震作用下相碰撞时的动力响应进行了对比分析.研究表明,碰撞使得基础隔震结构的加速度反应增大,但仍小于非隔震时发生碰撞的加速度响应.通过对比分析得出地震作用时隔震建筑与两边相邻结构相碰撞的次数要远多于仅一边结构相碰撞的次数.

| Abstract: | A linear Kelvin contact model was used to simulate the impact of adjacent struct ures.The governing equations of the structural pounding system under near-faul t earthquake were set up,and the effect of isolation bearings was investigated. The impact of base-isolated structure with displacement-constraint devices,w ith base-isolated structures and with base-isolated structure were studied.Th e results showed that the pounding on the base-isolated structure leads an obvi ous magnification of its acceleration... |
