摘?要:采用對比試驗研究方式,通過對同尺寸、同配筋的現澆式型鋼混凝土剪力墻試件和預制裝配式型鋼混凝土剪力墻試件的低周往復加載試驗,研究了預制裝配式型鋼混凝土剪力墻的承載能力、滯回性能、剛度退化等抗震性能,以及灌漿銷栓式套筒連接節點對型鋼混凝土剪力墻抗震性能的影響趨勢。結果表明,預制裝配式型鋼混凝土剪力墻的承載能力、剛度、耗能性能均略低于現澆式型鋼混凝土剪力墻,但基本能夠滿足結構承載和抗震要求;對連接節點的分析可知,除了銷栓的抗剪能力外,加強銷栓與套筒和型鋼之間的緊固,可以更好的提升套筒的連接性能。Abstract:Bymeansofcomparativeexperimentalresearch,thelow-cyclereciprocatingloadingtestsoncast-in-placesectionsteelconcreteshearwallspecimenandtheprefabricatedsectionsteelconcreteshearwallspecimenofthesamesizeandthesamereinforcementwereusedtostudythetheseismicperformanceofprefabricatedsectionsteelconcreteshearwall,suchassuchasload-bearingcapacity,hystereticperformance,stiffnessdegradationandtheinfluencetrendofthegroutingboltsleeveconnectiontotheprefabricatedsectionsteelconcreteshearwall.Theresultsshowthattheload-bearingcapacity,stiffnessandenergydissipationperformanceofprefabricatedsectionsteelconcreteshearwallareslightlylowerthanthoseofcast-in-placesectionsteelconcreteshearwall,butitcanbasicallymeetthestructuralload-bearingandseismicrequirements.Theanalysisofconnectionjointsshowsthatbesidestheshearcapacityofbolts,strengtheningthefasteningbetweenthebolts,sleeveandsectionsteelcanenhancetheconnectionperformanceofthesleeve.
