【摘要】 通过考虑叠层橡胶支座和巨-子控制结构体系的非线性特性及相互影响,建立了结构体系模型,并通过改变叠层橡胶支座刚度、阻尼等动力参数,进行巨-子控制结构体系地震响应时程分析,对采用叠层橡胶支座隔震的巨-子控制结构体系的地震响应规律和特点进行了系统的研究。研究结果表明:叠层橡胶支座的刚度、阻尼等动力特性对应用叠层橡胶支座巨-子控制结构体系的减震效果起重要作用。更多还原

【Abstract】 In this paper,the characteristics of seismic response of Mega-sub structural system with laminate-rubber bearings are investigated by using nonlinear time-history analysis.The dynamic parameters of laminate-rubber bearings and the seismic input are changed.The nonlinear properties and interactive effect of laminate-rubber bearing and Mega-sub structural system are also considered.The results show that the rigidity and damping of the laminated rubber isolation bearings are important factors of damping effect of Mega-sub structural system.更多还原
