Abstract: The column top joint of Cross Gate Exhibition Center was designed and there are five structural forms with different diaphragm stiffener and vertical crossing stiffener arrangements. Finite element analysis was carried out on the joint under the same load case using ABAQUS software. Then, the mechanical behavior of the five joints were compared in actual load case whereby the different effects of the diaphragm stiffener and vertical crossing stiffener were compared. Based on the comparative analysis of the joint bending stiffness by software calculation, some suggestions of joint forms with better safety, reliability, reasonable force transfer and construction feasibility are presented.

Keywords: diaphragm stiffener, vertical crossing stiffener, finite element analysis
