FIELD: construction.
SUBSTANCE: composite reinforced concrete bridge span includes the metal main beams integrated by cross braces, on which units of reinforced concrete cross-division slab of carriage way are fixed with formation of console parts on their joints, fastened with steel plates, reinforced with stiffening ribs. External stiffening ribs are arranged along the contour of vertical sides of edges of adjacent cantilever arms of cross-division slab units. External stiffening ribs of adjacent steel sheets are attached to them at their outer edges. Internal stiffening ribs are arranged within the contour, formed by the outer stiffening ribs.
EFFECT: improving quality of the composite reinforced concrete bridge span due to the simultaneous increase in carrying capacity and traffic capacity, increase of residual life of the bridge.
