Dar Journal on Structural Engineering 2320 - 2343 3 3 34 40 Cold Formed Steel, Buckling, Special Design Criteria, Innovative Sectional Profiles Cold formed steel structures are structural products that are made by forming plane sheets of steel at an ambient temperature into different shapes that can be used to satisfy structural and functional requirements. In recent years, the demand for high strength materials for wide range of structural applications has been instrumental for more developments in cold-formed steel sections as compared to the hot rolled steel sections. Therefore, the understanding of cold formed steel performance becomes an important issue to be studied. This paper holds three works. First, it reviews an introduction on cold formed steel structures. Second, it summarizes special design criteria and local buckling and post buckling strength of cold formed steel constructions. Finally, it offers a conclusion on the need for innovative sectional profiles over the conventional sections for cold formed steel. September - November 2014 Copyright © 2014 i-manager publications.
