摘要
为研究采用钢管混凝土键连接装配式混凝土结构预制柱和预制剪力墙的力学性能,进行了3个试件的抗剪试验&对比分析了钢管混凝土键间设置与不设置钢筋混凝土块的连接方式之间及与现浇结构的荷载-位移曲线、破坏过程及应力情况&结果表明:在钢管混凝土键间设置与不设置钢筋混凝土块的连接方式,其承载力和延性均优于现浇结构,但不设置钢筋混凝土块的连接方式,其初始刚度低于现浇结构;设置钢筋混凝土块的连接方式破坏阶段明显,承载力和延性高,抗震性能好,具有工程可行性.
In ordes to study the mechanicci properties of prefabricate#ccncrete cclumns and sheas walls ccnnected with concrete filled steel tubes(CFST),the shear test was ccnducted on three specimens.One of them was set with reinforccd ccncrete block between the CFSTs,another was not,and another was a cast-in-situ ccncrete structure.The load-displaccment curves,failure proccss and stress states amongthem were ccmpared and analyzed.Theresulte showed that the bearing capacity and ductility of the ccnnection modes with oe without reinforccd ccncrete block were all bettee than that of the in-situ structure.Howevee,its initial stiffness was lowee than that of the cast-in-situ structure aoeeheconneceton modewtehoueeetnaoeced conc ee ee b oock.The connec eton modewteh eetnaoeced conceeeeboock had obetousdamageseage,htgh beaetngcapactey,good ducetoteyand ntcesetsmtcpeetoemance,whtch mtghebeteastboetn ctetoengtneeetng.
