摘要
为探究一种新型PEC联肢墙结构的弹塑性时程分析方法,研究其应用于高层建筑的抗震性能,进行了3层对称双肢2/3缩尺试件的低周反复加载试验,对比了试验结果与有限元分析结果。研究结果表明:采用的有限元简化模型能够高效准确地对PEC联肢墙结构的屈服机制和破坏形态进行整体分析,该研究为这种新型PEC联肢墙结构在罕遇地震作用下进行弹塑性时程分析提供了可靠依据。
In order to study the elastic-plastic time history analysis method of a new type of PEC hybrid coupled wall and to study its seismic performance of tall buildings,the low cycle repeated loading test of a 3-story symmetric double 2/3 scale specimen is carried out,and the test results are compared with the finite element analysis results. The results indicate that the simplified finite element model can effectively and accurately analyze the yield mechanism and failure mode of the PEC hybrid coupled wall structure as a whole.The study provides a reliable basis for the elastic-plastic time history analysis of the new type of PEC hybrid coupled wall structure system under extreme seismic excitations.
