摘要
通过对足尺焊接空心鼓节点的试验和非线性有限元弹塑性分析 ,进行了节点的力学性能研究 ;并通过有限元计算 ,对空间受力的鼓节点进行了多参数、多工况计算 ,推导了其承载力计算公式。
Welded hollow truncated joint is a new type of joint.The static behavior of the joint has studied through the static test of a small shell with full scaled joints,and through the elastic plastic computation of nonlinear FEM.The bearing capacity of the hollow truncated joint is studied under the condition of all kinds of parameter.And the formula of bearing capacity is deduced.The results are meaningful to develop this kind of joint in the single layer latticed shell.
