摘要
本文介绍了由滑动摩擦元件和限位消能元件组合而成的基础滑动隔震装置,探讨了两种元件的基本性能和其匹配关系,并进行了等效质点系模型振动台试验和数值分析,提出了该体系的设计方法,试验研究表明,采用本文建议的基础滑动隔震装置,能显著地降低上部结构的地震反应,使结构的抗震性能获得显著改善。
In the paper,a base isolation system is composed of the sliding device and displacement restriclor and energy absorber is introduced.The properties and optimum scale of both devices are discussed.The shaking table tests and numerical analyses for the equivalent lumped model of mass system are conducted,and Design method of this systems is given.Test show that the earthquake response of superstructure is reduced considerably due to this base isolation system,the aseismic behavior for the structure is much improved.
