钢球-限位系统隔离结构水平地震的效果分析

摘要
本文对基底设置钢球、基础限制位移的隔震系统进行了理论分析,研究了摩擦系数、限位大小和限位装置刚度对结构地震响应的影响.对纯摩擦基础隔震系统,结构地震反应与结构周期和地震卓越周期无关,而基础位移的限定又使结构的反应依赖于地震波及限位装置刚度,并在一定程度上改善了地震力对结构的作用.
In this paper, theoretic analysis is done to a new earthquake isolation system with steel rolling in base and limiting displacement. The influence of the fricting coefficient, gap dimension and stop stiffness is studied. The structural response is independent of the periods of structure and earthquake waves ,but the gap can create an extremly high acceleration response.
