Cold-formed structural members are steel components that have been put into their cross-sectional shape by cold bending of flat sheets. Local compressive buckling must be carefully considered in designing such members, which are usually very thin. Basic design techniques outlined include use of reduced effective widths, reduced allowable stresses, and consideration of overall member buckling and torsional-flexural buckling. Applications are described, and the results of a survey of engineering schools are included which reveals that most engineering students are not exposed to the field of cold-formed steel design.
