| 摘 要： | 本文在同时考虑隔震层及其上、下部结构非线性的基础上,对一高层装配式层间隔震结构进行了动力弹塑性分析。通过分析结构地震响应,研究其不同地震波输入下的抗震性能。并通过增量动力分析(IDA)探讨高层装配式层间隔震结构在超大地震下的损伤机理和失效破坏模式,为高层层间隔震技术的发展提供了理论依据。

| Abstract: | This paper presents elastoplastic time history analysis of a high-rise prefabricated structure with inter-story isolation system.A fiber model for a real high-rise prefabricated structure was developed using PERFORM 3D,and the nonlinearity of isolation system,superstructure and substructure are taken into consideration.In order to investigate the seismic performance of the high-rise prefabricated structure under rare earthquakes,incremental dynamic analysis(IDA) is carried out for various ground motions.Seismic responses of the high-rise prefabricated structure with inter-story isolation system were analyzed.Furthermore,damage mechanism and failure mode of the inter-story isolation structure is studied,which is helpful for promoting the development of the high-rise inter-story isolation technology. |
