Abstract

Cold Formed steel (CFS) is the products made by rolling or pressing steel into semi finished or finished steel at relatively low temperature, commonly known as cold working method of strain hardening method, is dislocation generation within the crystal structure of the material . CFS products are found in all aspects of modern life, in home, shop, office, car body, petrol pump station. For the uses of structural members of greater length, cold rolled sections are used. Cold formed steel sections are most efficiently used with structures of moderate loads and span, in which circumstances these cold formed steel sections can be cheaper than hot rolled steel members. This investigation presents the experimental study of the behaviour of the flexural strength of CFS sections by using ‘Two Point Load’ method. Here two built up I sections were fabricated by using symmetric channel section with the help of bolts provided in the web part of the section. One of the built up I section was provided with angle stiffeners. The moment in the zone between the two point loads were same and that portion is known as pure bending zone. Flexural strength was increased by providing angle stiffener throughout the length of the sections at the spacing of 40 mm between two stiffeners.
