摘　　要：钢管混凝土边框剪力墙是一种新型剪力墙,它将混凝土剪力墙侧向刚度和承载力大的优势与钢管混凝土柱抗震延性好的优势相组合.为了确保抗震安全,需充分发挥钢管混凝土边框柱与钢筋混凝土剪力墙组合的优势,合理设置二者之间的抗剪连接键.为了研究不同形式连接键的连接性能,对6个1/2缩尺的带不同形式连接键的模型试件进行了低周反复荷载试验研究,对比分析了各模型的承载力、耗能、滞回特性及破坏特征.试验表明:经过合理设计的连接键能保证钢管混凝土边框柱与剪力墙之间具有可靠连接,使二者共同工作.Shear wall with concrete filled steel tube columns is a new kind of shear wall,which can fully display the advantages of the big lateral stiffness of concrete shear wall and good seismic behavior of concrete filled steel tube column.In order to bring the advantages into full play and guarantee seismic safety,it is important to design a reasonable shear connection between constructional measures.For studying working performance of connection of constructional measures,experiments of 6 joint models with different connection constructional measures have been done by applying low frequency circle load.The load-carrying capacity, energy dissipation,hysteretic properties and the failure features of each moedl are contrastively analyzed.The experiment indicates that safe connection between concrete filled steel tube column and concrete shear wall can be assured by adopting reasonable connection of constructional measures.
