摘　　要：为分析T形柱边节点承载力,采用ANSYS软件对其进行非线性有限元分析.通过与试验结果的对比,验证计算结果的可行性.分析了节点水平箍筋对节点承载力的影响,结果表明,水平箍筋的数量、截面积及钢筋强度等级的提高可以大幅提高节点承载力.同时,以斜压杆原理对现有的节点剪力公式进行了改进.To study T - shaped exterior joints of RC column, the FEM program ANSYS is applied to the nonlinear analysis on them. The comparison between experimentation and computation shows that the result is available. The effect of stirrups on the shear bearing capacity of the joints has been studied. It is indicated that enhancing the number, area, strength grade of stirrups can greatly promote the bearing capacity of joints, and an improved formula is presented based on the theory of truss.
