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.
