ABSTRACT:
A bridge which has a bridge deck constructed of corrugated checkered metal plate and which is supported by a plurality of side-by-side box beams carried by spaced apart beam supports. The box beams have upright sides which are connected to upper and lower chord plates all of which are constructed of corrugated plate having corrugations which run parallel to the length of the box beams and which have a large, e.g. 16 .times. 6 inch corrugation pitch and depth. The chord plates and sides are bolted together at spaced apart intervals. Thin walled shear plates are placed against the box beam sides and bolted to the corrugation troughs of the sides and they carry vertically acting shear loads while their connection to the box beams prevents them from buckling. A concrete layer is poured on top of the bridge deck so as to form a mechanical interlock between the concrete and the deck to thereby structurally integrate the concrete layer with the remainder of the bridge. A longitudinal camber can be incorporated in the box beam.
