钢框架内填预制带竖缝钢筋混凝土剪力墙抗震性能试验研究

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。

Experimental study on seismic behavior of steel frame with prefabricated reinforced concrete infill slit shear walls

In order to inprove seismic prformance of steel frame with prefabricated reinforced concrete infill slit shear walls(SFPCW),the ear bar device was used in the connection between the steel frame and the infill wall.Two one-bay,two story,one-third scaled models of SFPCW were tested with low cyclic load.The working perfomance of ear bar connection,the cracks developmented in infill walls and deformation performance of SFPCW were investigated.And the failure mode,hysteretic behavior,stiffness degradation,deformation and ductility and energy dissipation of composite structure were analyzed.Experimental studies show that no failure occurs in the connection between the steel frame and the infill wall because ear plates below and up the beam-to-cloumn connections are added in the specimens,and the connection device of ear plate presents good working performance.The SFPCW has good ductility with the ductility factor greater than 3.And the failure of infill walls is coused by the penetrating crack along the root of slits.
