| 摘 要： | 设计制作了一种摩擦摆隔震支座,并将其置于基础与上部结构之间,完成了一6层单跨钢框架摩擦摆隔震体系模拟地震振动台试验。针对不同场地从模型振动台试验和有限元计算两个方面进行了全面研究,并将两者结果进行比较。试验及有限元分析结果表明:理论分析和试验研究结果吻合较好,摩擦摆隔震装置能够有效的延长上部结构的自振周期,限制隔震层过大位移,同时具有自动回位的功能,有效减少了地震作用对上部结构的影响,隔震效果明显。

| Abstract: | A kind of FPS bearings is designed for isolating superstructure and foundation in a six-story single span steel-frame model subjected to shake table testing.Using both shake table tests and finite element analysis,different site responses were analyzed and compared.The experimental and finite element analysis results indicate that,the FPS is an effective isolation device that can lengthen the natural period and reduce the earthquake effect on upper structure. |
