| 摘 要： | 基础隔震体系分为橡胶基础隔震、滑移基础隔震和并联基础隔震体系.首先,建立该基础隔震体系结构的数学模型,隔震层采用双线性滞回模型.研究在不同隔震层屈服剪力和隔震周期时,不同隔震系统对地震反应的影响.在SIMULINK环境下对隔震结构体系进行仿真动力分析.经仿真分析表明,对于多层规则型房屋结构,经合理设计的并联基础隔震体系兼有橡胶垫和滑移基础隔震体系的优点,为最佳方案选择.

| Abstract: | The base-isolation systems consists of elastomeric,sliding and resilient-friction base isolation(R-FBI) systems.The numerical model of the base-isolation system is established.And the isolators are modeled by bi-linear hystereticmodels.The influence of the isolation systems on the response of the isolation structure is studied under the variation of parameters,such as isolator yield force and isolation time period.The simulink method is adopted to solve the dynamic differential equations.The simulation result shows that a reasponable designed R-FBI structure is an optimal scheme for the typically regular multi-storey construction.It has the advantages of elastomeric and sliding systems. |
