昆明某小区住宅楼隔震结构设计

Seismic Isolation Design of Certain Residential Building in Kunming

该文主要介绍了昆明某住宅小区采用隔震技术时的隔震结构方案选取、隔震支座选取及布置、地震波选取、结构减震系数确定等,并采用时程分析法对隔震结构的地震反应进行了分析计算,按照规范要求对该住宅楼做了隔震设计。借助有限元软件Etabs及Satwe软件对该抗震剪力墙结构住宅楼进行了隔震和非隔震动力特性分析研究,分析结果表明隔震结构延长了结构的周期,使结构的加速度反应大大减小,隔震结构在大震作用下基本上处于弹性工作状态。以期为今后的隔震结构分析、设计工作提供一定的经验和参考。

In this paper, we describe the isolation structure scheme selection, isolation bearing selection and arrangement of seismic wave selection, structural damping coefficient determined, etc., analyze and calculate the seismic isolation structure by using time-history analysis method, combining with regulatory requirements for the residential building made isolation design. By using the finite element software Etabs and Satwe software, we describe the isolated and non-isolated dynamic characteristic of one residential building in Kunming. The analysis results show that the structure of isolated structures extended period, the structure of the acceleration response greatly decreases, isolated structure under strong earthquakes basically is still in flexible working condition. This isolation structure will provide some experience and reference for future analysis, design work.
