摘要
本文以9度区某高层建筑为背景,重点介绍摩擦摆支座隔震的工作原理、设计参数以及设计流程和方法。分别采用铅芯橡胶支座和摩擦摆支座方案进行了隔震设计,以两种方案的隔震层力学简化模型的相似性为基础,比较两种隔震设计方案的异同,通过时程分析方法比较了两种隔震方案的隔震效果。研究结果表明,尽管两种支座特点迥异,但只要控制隔震层力学参数相似,便能得到相近的减震效果。
This paper presents the basic principle, design parameters and design process of isolated structure using Friction Pendulum System （FPS）, taking a high-rise building located in intensity region of 9 as study background. Based on the mechanic similarity of isolation floor, lead rubber bearings （LRB） and friction pendulum system （FPS） are used to conduct isolation design separately. Differences are compared between the two design schemes. Time history analysis （THA） is used to evaluate the isolation effect. Results illustrate that despite the different iso- lation devices, similar isolation effect can be obtained if the mechanic properties of isolation floor are in control.
