摘　　要：相贯节点的强度计算是空间管桁结构设计中的一个重要方面。利用有限元软件ANSYS,考虑材料非线性和几何非线性,对K型方管搭接节点的极限承载力进行数值模拟研究,通过一些关系曲线得出搭接率及其他几何参数对节点承载力的影响。The intensity calculating of simple joints is one of the most important aspects in the design of space truss with hollow sections. By using the finite element method and considering material and geometrical nonlinear properties, numerical simulation analysis of the ultimate bearing capacity of lapped K type RHS joints is studied. The influence of the lapped ratio and other geometrical parameters on the ultimate bearing capacity is investigated and explained graphically.
