【摘要】 通过有限元软件ANSYS对空间KT型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,采用的加强方式在主管内部设置纵向加劲肋。研究结果表明这种加强方式对于空间KT型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。更多还原

【Abstract】 Numerical simulation analysis of the ultimate strength of welded space KT-type RHS stiffener joints under axial loading and bending are studied by the finite element software-ANSYS,the stiffening methods are set up longitudinal ribbed stiffener in the chord.The result is proved that it can improve the monomial strength of the space KT-type joints,and the range of strength augment is related to some geometrical parameters.更多还原
