多层排架结构工业厂房的静力弹塑性分析

Analysis on Pushover Analysis Method for Multi-storey Bent Industrial Structure

目前苏南地区出现了大量的多层排架结构厂房,然而国内外对这类多层排架结构的抗震性能研究却很少,这就出现了对该结构的理论研究远远落后实际工程的情况,所以对多层排架结构厂房在罕遇地震作用下的弹塑性反应研究具有重要的现实意义。本文采用Pushover分析方法,对多层排架结构进行力学模型简化,得出多层排架结构的弹性及弹塑性层间位移,和在罕遇地震作用下该结构塑性铰的出现位置及顺序等结果,进而对多层排架结构的设计和施工提出建议。

Recently there are a great mount of multi-storey industrial plants built in the south of Jiangsu province.We have done a lot of work in the single-storey industrial plant until now,but there are few theoretical achievements in this multi-storey bent structure industrial plant,the seismic behavior in especial.The theoretical research falls far behind the practical engineering.Therefore,there are great theoretical and practical significance in the analysis for the elastic-plastic behavior of multi-storey industrial plants built by bent structure under the action of the rarely earthquake.In this thesis,we use the Pushover Analysis method in order to research on the seismic behavior of the multi-storey bent structure.Simplifying the mechanical model of the multi-storey bent structure to get the displacement between stories and the locations and the order of the plastic hinges for the multi-storey bent structure in order to bring forw
