摘　　要：采用微分型滞回恢复力模型模拟隔震支座的恢复力特性,通过对基础隔震密肋壁板大开间结构动力性能的分析表明,采用隔震技术可以有效降低上部密肋壁板大开间结构的地震反应,使其既达到抗震设防的要求,又满足建筑功能的需要。The differential hysteretic restoring force model is used to simulating the characteristic of restoring force of isolation bearings. Through the analysis of dynamic properties on large bay multiribbed slab frame structure with base isolated, it is proved that the seismic response of large bay multiribbed slab frame structure could be greatly reduced by means of base isolation techniques, so that the superstructure can be achieved the seismic fortification demand and fulfilled the building functional desire.

关 键 词：微分型滞回恢复力模型 基础隔震 密肋壁板大开间结构
