The Static Analysis about Complicated-Welded on Tubular Rectangle-Joints

Abstract:

Welded rectangular steel tubular joints have been widely used in large span complicated steel structure engineering .With the type of the joints and structural measures complicated, there is no suitable joints theory formula in design specifications. In this paper, two different structural measures types of umbrella steel truss # 8 joints and 68 # joints in a Railway Station are static analysis ,which is by means of finite element software ANSYS and based on the principle of the joints member loading simultaneously. The analysis results show that: in the case of the joints member loading simultaneously, the carrying capacity variation of each member is not uniform coordination; With the different angle between the branch pipe of joints and main pipe, the changes of the degree of stress concentration in the four side surfaces of the member is different. The maximum difference is about 2-fold; compared 68 #joint with 8 # joint, its degree of stress concentration on the overall is small, which prove that structural measures of its domain joints is reasonable.
