Hogging moment area structure of steel-concrete slab truss composite beam bridge

The utility model discloses a hogging moment area structure of a steel-concrete slab truss composite girder bridge, belongs to the field of bridge engineering, and solves the problem that a bridge deck slab of a hogging moment area of an existing steel-concrete slab truss composite girder bridge is in an unfavorable stress state. The bridge deck comprises a bridge deck and a plurality of trussed beams arranged in parallel, a bottom plate is arranged between adjacent trussed beams, the bottom plate is of a cavity structure, a stiffening steel plate is arranged in a cavity of the bottom plate, a plurality of first holes are formed in the stiffening steel plate, and the cavity of the bottom plate is filled with concrete. The bottom plate of the cavity structure is arranged between the adjacent trussed beams, and the stiffening steel plate and the concrete are arranged in the bottom plate, so that the buckling resistance of the steel pipe wall of the lower chord member is further improved, and the compression bea
