摘要

通过在钢筋混凝土剪力墙边缘设置边框,利用边框对墙板的约束效应,可明显提高剪力墙的延性,改善其抗震性能。边框的形式主要有钢筋混凝土边框、型钢混凝土边框、钢管混凝土边框等,其中,钢管混凝土组合剪力墙具有经济性好、施工方便等优点。应用ANSYS有限元程序对钢管混凝土组合剪力墙的滞回性能进行计算和分析,结果表明这种结构体系具有良好的延性和耗能能力。
Because of the composite effect of boundary members,such as RC frame members,SRC frame members and CFST frame members,seismic behavior,including ductility,of RC(reinforced concrete) shear walls will be improved enormously.There are many merits by using CFST(concrete filled steel tube) frame as boundary members because of its relative economy,convenience of construction and superior bearing capacity.Hysteretic behavior of a CFST frame-reinforced concrete infilled wall has been analysed in this paper.Results show that this kind of composite system has a good ductility and energy dissipation capacity.
