Steel-Concrete Composite Bridge Deck Structure and Bridge
Abstract Disclosed are a steel-concrete composite bridge deck structure and bridge, comprising: an ultra-high performance concrete slab; a cross beam, which is arranged along transverse direction of bridge and is located below the ultra-high performance concrete slab, and the cross beam is connected to 5 the ultra-high performance concrete slab by means of shear studs; and a steel rib, which is arranged along longitudinal direction of bridge, and the steel rib passes through the cross beam and is cross-fixed with the cross beam, and at the same time, the steel rib partially enters the ultra-high performance concrete slab. In the steel-concrete composite bridge deck structure and 10 bridge of the present invention, the cross beam and the steel rib may enhance overall tensile stiffness and flexural stiffness of the steel-concrete composite bridge deck structure, and when ultra-high performance concrete materials are adopted, the thickness of the concrete slab may be designed to be thinner, thereby reducing the overall weight of the steel-concrete composite bridge is deck structure. Therefore, the overall stiffness of the steel-concrete composite bridge deck structure can be improved, and the overall strength, durability and safety of the bridge can also be improved at the same time.
