Cold formed light gage steel shapes would appear to be an attractive target for structural optimization procedures. In contrast with rolled sections, where shapes and dimensions are fixed by the economics of production, there is scope for choice of dimensions in cold formed steel in order to achieve the objective of minimum weight or minimum cost. At the same time, light gage steel shapes are manufactured in relatively large quantities and economies of weight or cost should result in total savings that justify the expense of the numerical optimization effort.
