摘要
等宽K型方管节点是一种外形美观、制作方便、承载力高的节点形式。本文利用非线性有限元分析的方法对等宽K型方管间隙节点进行了数值计算 ,揭示了在弦杆轴力作用下此类节点的极限承载力、变形、刚度等随各几何参数的变化规律 ,得出了一些有用的结论 ,可供工程设计参考应用。
The directly welded K-type RHS-joints have the advantages of beautiful shape, manufacture and high load-carrying capacity. In the paper, nonlinear finite element analyses on the gapped K-type full-width RHS-joints were carried out. The relations of the load-carrying capacity and stiffness of the joints with variation of geometrical parameters were discovered. Some useful suggestions are put forward, for designing reference.
