摘要
结合某中学教学楼实例,全面阐述了基础隔震技术的应用。采用结构分析软件ETABS对建筑结构进行了空间模型的时程分析,通过分析对比隔震房屋和非隔震房屋的计算结果,采用隔震措施可以显著降低上部结构的地震反应,隔震结构在大震作用下其水平变形基本处于弹性状态,具有较好的抗震性能。本工程为隔震技术在类似建筑中的广泛应用提供了一个良好实例。
Based on an example of a middle school teaching building,the application of base isolation technology is presented.The nonlinear spatial model time history analysis of the structure are investigated by ETABS structure analysis software,through the analysis and comparison of the computational results of isolated building and the one non-isolated building,the calculation results of the structure shows that the horizontal earthquake action upon the upper structure can be greatly reduced by using base isolation technique,the horizontal distortion of the isolated building keeps fundamental elastic state under very rear earthquakes occurred and has excellent aseismic behavior.The research and design experience provides a great example for the wide use of the isolation technology in similar engineering.
