摘　　要：为研究水平钢筋连接方式对复合剪力墙节点抗震性能的影响规律,设计了水平钢筋伸入暗柱或不伸入暗柱两类组合节点。在循环荷载作用下,对两类节点共4个试件分别进行了抗震试验。通过对复合剪力墙节点的受力变形、破坏特征、滞回特性、延性以及耗能能力等方面进行研究,分析了复合剪力墙连接节点的抗震性能。通过对承载及变形、延性及耗能等指标进行对比分析发现:水平钢筋连接节点的开裂、屈服及极限荷载分别提高了2.42%、10.84%和9.25%;延性系数提高了10.26%;耗能系数提高了8.70%。研究结果表明:对剪力墙节点进行合理配筋和连接,可以有效地提高节点试件的整体抗震性能。In order to study the influence of the horizontal steel bar connection method on the seismic performance of the composite shear wall joints,this paper designed two types of composite joints,which were horizontal reinforcements with or without embedded column.Under cyclic loading,a total of four specimens of two types of joints were subjected to seismic tests.By studying the deformation,failure characteristics,hysteretic characteristics,ductility and energy dissipation capabilities of the composite shear wall node,the seismic performance of the composite shear wall connection node is analysed.Through comparative analysis of bearing and deformation,ductility,energy consumption and other indicators,it is obtained that the cracking,yielding and ultimate load of the joints of horizontal steel bars are increased by 2.42%,10.84%and 9.25%respectively;the ductility coefficient is increased by 10.26%;the energy consumption coefficient has been increased by 8.70%.It can be seen that the overall seismic performance of the joint specimens can be effectively improved by reasonable reinforcement and connecting the shear wall nodes.
