ABSTRACT
To improve the construction efficiency of the steel plate composite beam bridge deck and reduce the construction steps of wet joints, this paper proposes a method to eliminate shear studs and internal prestressing in wet joints of steel plate composite beams. This significantly enhances the construction efficiency of the steel plate composite beam bridge. By establishing a spatial finite element analysis model and comparing it with a traditional bridge deck in terms of stress analysis, the results show that the two optimized structures have minimal impact on the stress distribution of the bridge deck. In particular, the stress increase in the bridge deck with eliminated wet joint shear studs is less than 4%, and the reduction in stress reserve due to the absence of transverse prestressing in wet joints is only 1 MPa.
