Abstract

In order to investigate mechanic behaviors of the orthotropic deck welding conformation details of highway steel bridge, take Zhongdu Yangtze River Bridge located in Jiangjin of Chongqing district as an engineering background, the 3-dimension spatial section model of steel box girder was firstly established based on the numerical finite element method, and then the stress level of welding conformation including the top plate of orthotropic deck, stiffening rib and transverse diaphragm was studied. The numerical analyzed results show that the stress level of welding conformation is mainly influenced by the second system and the third system. The mechanical performance of box girder is specifically represented as global bending action, global shearing action and local supporting action, which reflects significant local stress state. Also, the degree of the above mentioned actions for different conformation details is different.
