Abstract：
Combining with the practical project of an exhibition, the spatial cast-steel joint with three branches in the tree-like structure has been studied using ANSYS. The maximum stress distribution of joint is analyzed when the force is applied on different branch on three conditions including axial force, bending moment and the combinative action of the both. The effect of the different chamfering radius between chord and branch, and the different inside and outside chamfering radius between branches on mechanical behavior is analyzed. Study results shows that the maximum Mises stresses of the joint on three load conditions are far less than the yield strength and the joint is safe enough.
