摘要
基础隔震能有效减轻结构地震响应.但在近断层脉冲型地震作用下,隔震结构的隔震层会发生较大位移,导致隔震结构侧倾失稳.本文采用弹簧限位装置进行软碰撞限位,利用软件SAP2000计算近断层地震作用下限位隔震结构的动力响应,分析限位装置不同预留距离、不同限位刚度对隔震层最大位移和上部结构最大层间位移的影响.
The base isolation is effective to reduce earthquake responses of super-structure.The near-field pulse-type ground motion will bring about large deformation of base isolation layer.The base isolated buildings will buckle instability.The spring limiting devices are used to limit deformation of isolation layer.The dynamic responses of limiting isolated buildings is calculated by means of software for calculation SAP 2000 under near-field ground motion.The influences of different parameters of limiting devices,namely reserve space and limiting stiffness to maximum displacements of isolation layer and super-structure are analyzed.
