Abstract：
In a swimming pool project, bifurcate cast steel nodes are used in the tree-type structure and 3D3S structure design software is used for integral modeling calculation of the swimming pool, on the following aspects. The node stress is calculated under three different working conditions, including axial force, bending moment and mutual effect of axial force and bending moment, node stress distribution characteristics and position of maximum stress are analyzed; after research on the influence of different fillet radiuses on node capacity, it is found that fillet treatment could avoid concentration of node stress, lining form may influence the value and position of maximum stress, and appropriate fillet radius could obviously reduce the concentration of node stress.
