为考察结构体系隔振前后性能的变化规律,本文采用EATBS软件建立某商场框架结构体系的有限元模型,结合地震作用下剪力作用的响应和时程曲线反应谱进行隔震设置,对周期、层间剪力等计算参数进行分析验证。基于此开展了地震波作用下的时程分析,结果表明隔震后的结构基底剪力满足承载力的要求,隔震支座的反力均满足规范的要求,可为同类工程的隔震设计提供可靠的技术参考。
In order to investigate the variation of performance before and after vibration isolation, this paper uses EATBS software to establish the finite element model of a shopping mall frame structure system, and combines with the response of shear force under earthquake action and the time history curve response spectrum, Layer shear and other calculation parameters for analysis and verification. Based on this, the time-history analysis under seismic wave is carried out. The results show that the base shear of the post-isolation structure meets the requirements of bearing capacity. The reaction force of the isolation bearings meets the requirements of the standard and can be provided for isolation design of similar projects Reliable technical reference.
