摘要
针对目前普通隔震支座隔震减震效果较弱的问题,提出了一种新型组合系统的隔震装置以此来减轻地震动对结构的影响;基于组合装置的组成和受力变形特性建立恢复力模型,并进一步进行了力学参数分析,最后对组合隔震装置进行数值模拟。分析结果表明,该新型组合隔震装置具有较好的减震耗能效果,可同时控制结构在地震作用下的加速度响应与隔震层位移。
In view of the weak vibration isolation effect of common isolation bearings,a new type of seismicisolation device of combined system is proposed in this paper to reduce the impact of ground motion on thestructure.The resilience model was established based on the composition and force deformation characteristicsof the combined device,and the mechanical parameters were further analyzed.Finally,the combined isolationdevice was numerically simulated.The analysis results show that the new combined seismic isolation device hasbetter damping energy consumption effect,and can simultaneously control the acceleration response of thestructure under earthquake action and the displacement of the isolation layer.
