Abstract
A composite structural steel wall reinforced with concrete and a form system is described herein. The wall comprises a corrugated steel sheet defining a plurality of integrally formed, alternately inverted, spaced ridges. The ridges extend on opposed sides of the sheet and are separated by troughs defined by a rear face of the ridges on an opposite one of the sides and an integrally formed side wall of opposed ridges on a common side of the sheet. The side walls have openings therein. A first wall structure is secured to at least some of the ridges on one of the opposed sides of the corrugated steel sheet. A second wall structure is secured to at least some of the ridges on the other of the opposed sides of the corrugated steel sheet. The first and second wall structures form at least an integral part of the finished wall surfaces and are spaced apart and interconnected substantially parallel to one another by the corrugated steel sheet whereby to constitute a form to receive concrete from a top end thereof to form the structural steel wall reinforced with concrete.
