description The prefabricated steel-UHPC combined bridge deck slab beam comprises hollow rectangular prefabricated steel plate beams which can be detachably spliced with one another, grooves are evenly distributed in the hollow rectangular prefabricated steel plate beams in the longitudinal direction, and shear force connecting pieces are vertically arranged in the grooves; ultra-high performance concrete is poured on the hollow rectangular prefabricated steel plate beams to form UHPC panels; the bridge deck slab is small in overall thickness, large in clearance under the bridge and light in self weight. Factory-like integral manufacturing of the fabricated steel-UHPC footbridge panels is utilized to guarantee interface connection reliability, concrete cast-in-place of steel-concrete combination portions and transverse connection between the footbridge panels are avoided, simplicity, convenience and rapidness are achieved, and meanwhile fabricated construction can shorten the construction period, reduce influences on con
