摘　　要：应用材料非线性和几何非线性有限元法对空间XK形节点圆管相贯节点进行了数值计算,分析了节点在荷载作用下应力的发展、变化过程及节点变形,并将分析结果与相关试验结果进行了比较,在此基础上得出一些有用的结论。The ultimate strength of tubular XK-joints is investigated numerically by using the finite element method with close reference to both material and geometrical nonlinearity. The distribution of stress and the joint deformation are analyzed. By comparing the FEM results with those of test, some useful conclusions are reasoned out.
