摘要

竖向近断层地震动作用下易造成隔震结构内部非结构系统产生地震响应放大现象。为研究近断层地震动下隔震结构-内部非结构的动力反应控制机理，建立了竖向地震动下隔震结构-内部非结构耦合系统分析模型。采用非线性时程反应分析方法分析了附加竖向准零刚度系统的非结构元件的响应控制效果。基于能量分析方法建立了竖向近断层地震动作用下隔震结构-内部非结构耦合系统能量平衡方程。研究结果表明对于不同自振频率的隔震系统，当采用竖向准零刚度对非结构元件进行地震响应控制时，减震效果较好。有控系统的竖向弹性恢复能和阻尼耗能要大于无控结构，通过选取合适的阻尼比可有效控制非结构元件的地震响应。

Abstract

Near-fault vertical ground motions tend to cause the amplification of seismic responses of nonstructural components in an isolated structure. To study the mechanism of dynamic response control for nonstructural components in the isolated structure under near-fault vertical ground motions, a model for the base isolated structure-nonstructural coupling system was established. The seismic response control effect of nonstructural components with the quasi zero stiffness of isolation system was analyzed by using the non-linear time history response analysis method. Based on the energy analysis method, the energy balance equation for the base isolated structure-nonstructural coupling system was established. The results show that when using the vertical quasi zero stiffness system, the seismic isolation efficiency of nonstructural components is remarkable for the base isolation system with different natural frequency. The vertical elastic recovery and damping energy of the seismic isolated structure model with quasi zero stiffness are much bigger than those of the base isolated structure with fixed nonstructural component system. It is beneficial to control near-fault vertical seismic responses of nonstructural components by setting reasonable damping ratio.
