摘　　要：通过对一具有足尺节点的单层球面网壳模型静力试验和非线性有限元计算 ,分析了焊接空心鼓节点的刚度对单层网壳结构受力性能的影响 ,研究了该类节点的网壳结构非线性计算模型的适用性 ,并对焊接球承载力进行了修正 。Through the static test of a small shell with full\|scaled joints and the computation by the use of nonlinear FEM,the effect of the rigidity of truncated joints on the static behavior of single\|layer latticed shell was analyzed and the application of the mathematical model of nonlinear FEM was also studied.The designed carrying load capacity of the hollow joints was modified.It is significant for the development and application of welded hollow truncated joints in the single\|layer latticed shell.
