摘　　要：针对短肢剪力墙抗震性能相对较弱的缺点,将新型的约束型配钢方式引入短肢剪力墙的边缘构件中,并沿墙肢高度方向每隔一定的间距设置无粘结预应力钢绞线,施加横向预应力,以使剪力墙边缘构件核心区的混凝土在竖向荷载作用下处于双向甚至三向的受压状态;并利用通用有限元软件ABAQUS计算,得到该种结构在反复荷载作用下的骨架曲线,计算曲线与试验曲线进行了比较,吻合较好;同时分析了不同预应力施加值对结构抗震性能的影响。According to the faults of short-shear walls＇ seismic performance, new members of the edge with steel tube are introduced to short-shear wails, transverse prestressing is exevted along the wall high direction and the certain spacing in order to make the concrete structural core edge on the vertical load in two-way even three to take pressure condition. And the skeleton curves in the iterative load are derived by the ABAQUS software, and the simulated curves agree well with the experimental results. Also the influence of the bearing capacity and seismic behavior under the different size of prestressed force is analyzed.
