摘　　要：通过有限元软件ANSYS对设有双T加劲板连接件的方钢管混凝土柱—钢梁节点进行了空间非线性分析,研究节点区在单调荷载和低周反复荷载作用下的受力机理,指出方钢管混凝土柱—钢梁节点具有优良的延性及耗能能力,且加劲板的设置有效地降低了节点区的应力集中。The article carries out space nonlinear analysis of concrete filled rectangular steel tubular column-steel beam joint installed with double T-type reinforced plate through finite element .software ANSYS, studies the force mechanism of joint zone trader monotonic loading and low cyclic loading, and points out that concrete filled rectangular steel tubular-steel beam joint has well ductility and energy dissipation and the installation of reinforced plate effectively reduce the stress concentration of joint zone.
