摘要
结合某工程实例,全面阐述了基础隔震技术的应用。采用结构分析软件SAP2000和ETABS对主体结构进行了空间模型的时程分析,隔震房屋和非隔震房屋的计算结果表明,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。通过对隔震及非隔震结构模型的地震模拟振动台试验,验证了计算分析的正确性和隔震结构的安全性,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 engineering, the application of base isolation technology is presented. The nonlinear spatial model time history analysis of the structure is investigated by SAP2000 and 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 show that the horizontal earthquake action upon the upper structure can be greatly reduced by using base isolation technique, and the horizontal distortion of the isolated building keeps elastic state under very rear earthquakes and has excellent aseismic behavior. In addition, the earthquake simulation shaking table tests of the isolated and non-isolated structural model are finished. The accuracy of calculation analysis and the security of isolated structure are verified.
