将回归得到的X形相贯节点轴向刚度、平面外弯曲刚度及平面内弯曲刚度的计算公式引入管结构分析设计软件STCAD,对某体育馆单层网壳屋盖结构进行了静力和整体稳定性分析。结果表明,X形相贯节点的刚度随着结构内力的增加而降低,节点的非刚性性能对单层网壳的变形及整体稳定性有显著影响。 The formulas of axial stiffness, out-of-plane bending stiffness and in-plane bending stiffness of X-shaped cross-connected joints were introduced into the structural design software STCAD to simulate the static and overall stability of single-storey reticulated dome roof analysis. The results show that the stiffness of X-shaped cross-joints decreases with the increase of internal forces, and the non-rigidity of joints has a significant effect on the deformation and overall stability of single-layer reticulated shells.
