摩擦滑移隔震结构的减震分析

Seismic isolation analysis of structures with base sliding isolation

研究了摩擦滑移支撑结构的动力响应。采用Newmark法,对一个算例结构在加摩擦隔震前、后两种情况下,分别进行了动力反应分析和比较,结果表明,摩擦滑移隔震技术具有明显的隔震效果。

The response of structures with friction sliding supports is studied in this paper.Using Newmark's method,dynamic response of a example structure with base sliding isolation is analyzed,and it is compared with dynamic response of fixed base structure.The analysis results indicate that base sliding isolation has obviously isolating effect.
