摘　　要：通过有限元软件ANSYS对K形方管相贯焊接加强节点轴力和弯矩作用下的极限承载力进行了数值模拟研究,采用的加强方式为主管壁加厚、在主管内部设置横向和纵向加劲肋。研究结果表明三种加强方式对于K形方管节点的单项承载力都有不同程度的提高作用,且提高幅度与几何参数有关。Using the finite element software-ANSYS, numerical simulation analysis of the ultimate strength of Welded K-type RHS stiffener Joints under axial loading and bending are studied, the stiffener methods in this paper are increasing the thickness of chord and setting transverse or longitudinal fibbed stiffener in the chord. It was proved that they can all improve the monomial strength of the joints, and the range of augment was related to some geometrical parameters.
