A composite structural support which may be utilized as a beam or assembled with similar supports to form a building floor or a bridge deck utilizes an open core element, made preferably of suitably treated fluted paper, upper and lower thin steel skins, and a layer of concrete poured over the top skin. Modules comprising the hollow core element and the upper and lower steel skins are fabricated to lengths required for building floor and bridge spans and, when joined by welding the upper and lower skins of adjacent elements along their full lengths, provide a floor or deck structure of a large span. The open core paper elements may be alternately fabricated from single face corrugated webs or open face double wall webs that are slit to form narrow equal width strips stacked and glued face-to-face.
