TL;DR: In this paper, a review of the peculiarities of the design of light-gage steel construction is presented, along with illustrated examples which describe the present range of useage of cold-formed, light-grain steel construction.
Abstract: Structural members, panels, and decks cold-formed from sheet or strip steel have gained wide acceptance in building construction. The paper reviews some of the peculiarities of the design of light-gage construction. Methods for such design are given in the pertinent Specification of the American Iron and Steel Institute, based largely on research carried out at Cornell University. Performance of thin-walled steel structures is illustrated by selected examples from this research. Current fabrication methods are briefly mentioned and the second part of the paper contains illustrated examples which describe the present range of useage of cold-formed, light-gage steel construction.
