Wang Liucheng2 Yu Fuli2 (1.School of Civil Engineering Zhejiang Industry Polytechnic College Shaoxing Zhejiang 312000 China; 2.Zhejiang Jinggong Steel Building Group Co.Ltd.Shaoxing Zhejiang 312030 China Abstract:At present the analysis of stiffener thickness influence on bearing capacity of welded ball joints is not so much.So far there are no any specifications of structural design specify the influence degree of stiffener thickness on bearing capacity of welded ball joints.How to select the thickness of stiffener economically and safely is a question worth considering.In order to effectively evaluate stiffener thickness influence on bearing capacity of ring stiffened rib this paper applies the finite element software ABAQUS to establish the model of ribbed welded hollow ball joints.It proposes methods to construct the thickness of welded hollow ball joints.At the same time it analyzes different stiff...
