ABSTRACT

The mechanical property of composite girder bridges is significantly influenced by the mechanical performance of shear connectors. The slip between the deck plate and steel girders caused by deformed shear connectors will have an impact on the mechanical property of the entire bridge. The slip impact of the clustered shear studs is taken into account in this article in order to reflect the actual structural condition. The influence of this consideration on the force performance of the steel plate composite girder bridge is then examined by creating an ANSYS finite element model. The study focused on the deformation and stress distribution of a composite girder bridge, and the calculation analysis reveals that taking shear studs slippage into account will result in lower stress results in the deck plate and steel girder and higher overall deformation of the bridge. The longitudinal stress of the bridge deck is most significantly impacted by the shear studs connection performance, with a maximum stress variation of roughly 8%. The greatest deformation difference does not exceed 5%.
