摘　　要：为研究多层端板连接装配式钢筋混凝土框架(以下简称多层框架)结构的抗震性能,基于3榀1/2缩尺框架(XJ、ZP-1、ZP-2)试验,验证了有限元分析的准确性,按照现行规范设计了1榀2跨3层的端板连接装配式钢筋混凝土框架,运用ABAQUS有限元软件分析了在低周往复位移作用下结构的受力特性、刚度退化、耗能性能和延性系数。结果表明:在地震作用下,1榀2跨3层端板连接装配式钢筋混凝土框架结构的承载能力、耗能能力等受力性能均优于现浇框架结构,但其中柱受压损伤发展较快,这使得框架承载力和刚度下降较为迅速。To study the seismic performance of multi-story end-plate connected prefabricated reinforced concrete frame structures,based on the testing of three half of one scale frame specimens(XJ,ZP-1,ZP-2),the accuracy of finite element analysis was validated.A three-story end-plate connected prefabricated reinforced concrete frame with two spans according to current regulations was designed.The ABAQUS software was applied to analyze the structural response characteristics,stiffness degradation,energy dissipation performance and ductility coefficient under low-cycle reciprocating displacements.The results show that for the three-story end-plate connected prefabricated reinforced concrete frame structure,the load-bearing capacity and energy dissipation capability during seismic events are superior to the cast-in-place frame structure.However,the compression damage development of the central column is faster,leading to a rapid decrease in bearing capacity and stiffness of the frame.
