为改进钢框架内填预制带竖缝钢筋混凝土剪力墙的抗震性能,将耳板引入钢框剪与内填墙的连接中。通过2个两层单跨缩尺比为1∶3的钢框架内填预制带竖缝钢筋混凝土剪力墙模型试件的拟静力试验研究,考察了耳板连接的可靠性和内填墙裂缝的开展与结构变形能力,分析了结构的破坏机理、滞回性能、刚度退化、变形及延性和耗能能力等。试验结果表明:抗剪连接件(U形筋)在梁柱节点上下耳板的连接处未发生破坏,耳板连接具有可靠的工作性能;钢框架带竖缝剪力墙结构具有良好的延性,平均位移延性系数大于3;内填墙的承载力由竖缝根部的剪切破坏控制。
In order to improve the seismic performance of prefabricated vertical reinforced concrete shear walls with steel frame, the lugs are introduced into the connection between the steel frame shear and the filling wall. Through the pseudo-static test of two prestressed reinforced concrete RC shear walls with steel frames with one-to-three scale ratio of 1: 3, the reliability of the connection and the filling Crack development and structural deformation capacity, the failure mechanism of the structure, hysteretic behavior, stiffness degradation, deformation and ductility and energy dissipation capacity were analyzed. The test results show that the shear connection (U-shaped tendons) is not damaged at the joint of the upper and lower ear plates of the beam-column joints, and the connection of the lugs has reliable working performance. The steel frame with vertical shear wall structure has good ductility, The average displacement ductility coefficient is greater than 3; the bearing capacity of the filling wall is controlled by the shear failure of the vertical root.
