Research on Rigidity of Circular Tubular ZYY-Joint in Single Fold Surface of Multi-Planar Steel Structure of 26^th Universaide Shenzhen 2011

Abstract:

Due to its convenience of construction connection and simple appearance, steel tubular structure with simple joints is widely used in spatial structures. Tubular joint generally belongs to semi-rigid joint. Its different internal detail is closely related to the bearing capacity and stiffness of joints and its stiffness characteristic has some definite effects on the internal forces, deformation and bearing capacity of the steel tubular structure. In this paper, the roof structure of the main stadium of 26^th Universaide Shenzhen 2011 was selected as the engineering background. This paper also studied the comparison test on different structural forms of spatial circular tubular ZYY-joints of the peaks of its steel structure by scaling down as the proportion of 1:3, and carried out a numerical analysis on these joints by finite element software ANSYS. It shows that, results of numerical analysis coincide with the experimental results and the joint with ribbed stiffener has better bearing capacity and stiffness, which can well meet the engineering needs.
