Corrugated steel plate is formed from a flat plate stock and has a length of at least about 12 feet, a corrugation pitch of at least about 12 inches, and a corrugation depth of at least four inches. The plate has thicknesses of up to 1/2 inch and more. Also disclosed are structures such as tunnel-type, heavy load-supporting structures defined by upright and horizontal structure portions which extend over no more than about 180.degree. while being capable of supporting up to 40 feet of ground fill and payload thereon. The corrugated plate can be used singly or as double, spaced-apart plate assemblies which are hollow or filled with concrete or a like material, including steel reinforcing bars for the concrete. The corrugated plate can also be formed into vertical, sectional retaining walls, bin type retaining walls, bridge abuttment walls, flat support surfaces such as bridge decking, open air structures, guard rails, sheet piling, etc.
A load-supporting structure comprising at least one wall defined by a corrugated metal plate having a plurality of generally sinusoidal undulations defined by alternating, contiguous convex portions and concave portions, the spacing between adjacent concave and convex portions in a direction transverse to the plate being at least about four inches and the spacing between adjacent concave portions and between adjacent convex portions parallel to the plate being at least about 12 inches, a corrugated anchoring plate disposed transversely to the longitudinal extent of the undulations for anchoring an end of the first mentioned plate, the anchoring plate being shaped and dimensioned complementarily to the corrugated plate of the wall and oriented transversely with respect thereto, means securing lower ends of the wall to the anchoring plate bracing means connecting an upper portion of the wall with a portion of the anchoring plate remote from the lower end of the wall and comprising a corrugated bracing plate dimensioned complementarily to the wall and the anchoring plate and positioned perpendicular with respect to both, and means for securing the bracing plate to the wall at least adjacent an upper end of the wall.
