| 摘 要： | 鉴于上海环球金融中心结构体系及结构布置的复杂、结构高度及体型的超限，为了确保该建筑结构的抗震安全性和可靠性，除进行常规的计算分析外，还应对该结构进行弹塑性时程分析。本文建立了该结构的弹塑性时程分析简化模型，并编制了相应的计算程序。为了检验结构弹塑性时程分析的可靠性，首先对振动台试验的模型结构进行弹塑性时程分析，以便和试验数据进行对比。在此基础上对原型结构进行弹塑性时程分析，并对该结构进行了抗震性能评价。

| Abstract: | Because Shanghai World Financial Center is a structure with complex structural type and exceeds the code limits, besides conventional analysis, elasto-plastic time-history analysis of the structure was carried out. In order to validate the reliability of the analysis method, elasto-plastic time-history analysis for the shaking table test model of Shanghai World Financial Center building was carried out, and the comparison between theoretic analysis and test data was made. Elasto-plastic time-history analysis for the prototype structure of the building was accomplished, and accordingly the seismic performance of the structure was evaluated. |
