摘　　要：为了研究不同拼缝构造形式的自密实混凝土叠合剪力墙在低周反复荷载试验下的抗震性能,试验设计了4片不同构造形式的墙体,对比各试件试验过程所表现出的破坏特征,并对试件的滞回曲线、骨架曲线等抗震性能指标进行分析。结果表明:不同拼缝构造形式的自密实混凝土叠合剪力墙具有相似的破坏形态和刚度退化能力,但配置工字型钢的墙体延性性能最好;拼缝构造形式采用双柱或工字型钢能提高墙体的耗能能力,增强墙体的抗震性能。In order to study the seismic performance of self-compacting concrete composite shear walls with different joint seams under low reversed cyclic loading tests,4 different types of wall were designed.The failure characteristics of different specimen were compared,and the seismic behavior indexes such as the hysteretic curves and skeleton ones of the specimens were analyzed.Test results indicated that different joint seam forms of self-compacting concrete composite shear walls had similar failure mode and rigidity degradation,while the composite shear wall with H-profile steel showed better ductility performance.The joint seam of double column or H-profile steel structure could enhance structural integrity and improve the bearing capacity of walls.
