ABAQUS software is used in this paper in order to analyze the influence of the stability of the cast steel joints on the branch of the tree-shaped column.Especially focusing on the analysis of the influence of the types of nodes numbers of primary branch and cast steel node wall thickness on the calculation length coefficient of each branch.It shows that:the stability of the tree-shaped columns using the tubular joints is improved by using cast steel joints and the stability of each branch can be promoted by increasing the number of primary branch and the thickness of cast steel joint.The influence of wall thickn...
