Abstract
The shear flow bearing ratio of concrete slab and steel roof was theoretically deduced according to the distribution law of shear stress and shear flow of composite bridge deck section under the condition of complete connection between concrete slab and steel roof. It was proved that the longitudinal shear force between layers of composite bridge deck is smaller than that calculated by the formula of composite beam. The finite element calculation of complete connection between layers and discrete connection of shear studs simulated by spring element supported this view, which verified the correctness of the view that the vertical shear force of composite bridge deck section was mainly borne by the web. The arrangement of shear studs in transverse direction was explored. Results show that the shear studs should be arranged along the transverse full width of the composite bridge deck, the shear studs should be densified on both sides of the web, and the shear studs should not be arranged directly above the web.
