【摘要】探讨了铅芯橡胶支座胶支座(LRB)用于基础隔震体系时参数的优化配置问题,对一算例采用非线性时程分析法研究了不同地震波激励下的地震反应。结果表明,对于具体工程控震指标要求,可以通过优选LRB参数来实现。更多还原

【Abstract】 In this paper, the optimum parameter of baseisolated buildings with lead laminated rubber bearings(LRB) has been studied. The earthquake response of seismic isolation system excited by different ground motions has been investigated by the nonlinear timehistory response analysis procedure through an engineering example. The results show that seismic response of the system can be controlled by optimizing LRB parametrs for practical engineering.更多还原
