K形方管加强节点的承载力性能研究

The research of ultimate strength of welded K-type RHS joints

通过有限元软件ANSYS对K形方管相贯焊接加强节点的轴力和弯矩作用下的极限承载力进行了数值模拟研究,研究结果表明三种加强方式对K形节点的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. It was proved that three kinds strenth methods can all improve the monomial strength of the ioints of K-type, and the range of augment was related to some geometrical parameters.
