【摘要】 通过对不同参数的空间KK型方管节点的有限元计算,得出节点承载力与相关参数间的关系,并拟合出支杆的轴力系数n=-0.5(支杆受拉)时节点承载力的计算公式。另外,通过与平面K型节点对比,得出空间节点与平面节点承载力的比值。所得结论可为《钢结构设计规范》(GB 50017-2003)修订提供参考。更多还原

【Abstract】 After calculation by FEM of many multiplanar squaretube KK-joints with different parameters,it is obtained correlation between their load bearing capacity and relative parameters.At the same time,a formula to calculate capacity of KK-joint is inferred when axial force factor of branch tube n=-0.5(tensile).Moreover,through comparision of the planar K-joints,the load bearing capacity ratio of multiplanar KK-joint and planar K-joint is also obtained.Conclusions may be a reference for the modification of"Code for Design of Steel Structure"(GB 50017-2003).更多还原
