Study on Ultimate Strength and Buckling Modes of Cold Formed Steel Structures

Abstract

Stronger construction material is category from one of the steel structure are attain higher strength with stand the resistance of steel by natural as well as it could made in different shapes. The exact shape of steel structure and its profile are precisely designed from cross section to ensure Indian Standard along with mechanical and chemical characteristics. All over the country’s most of the industrialization is precise on sizes, shapes; strengths, storage practices and its composition of steel structure are used as per standards. cold-formed steel is effect with rolling of thin gauge steel sheet increasing the yield strength whose products are widely used in construction industries, as well as structure like columns, beams, joists, studs, floor decking, built-up section, telecommunication towers, electricity transmission steel tower, multi-storied steel structures, etc., due to its stronger and reduction in dead weight cold-formed steel is used. The dies are series of making various section of cold-formed steel structural member with different section and shapes by cold roll forming the steel to attain the preferred shape. As per the standard, nominal minimum yield strength of sheet steel rolled in cold-formed section is 250 N/mm2. However, user trend use of greater strength, but it could be lesser as 230 N/mm2.
