A Study on Square and Rectangular Hollow Steel Section Subjected to Torsion

Steel members have become one of the most popular building materials in the construction industry owing to its high tensile and compressive strength, high ductility, durability, longer span, aesthetic looks, etc. Steel members can be classified into various types based on the manufacturing process, chemical composition, types of section, etc. Steel members used in construction are subjected to various loading such as tension, compression, bending, and torsion. Only few studies (Ridley Ellis in Rectangular hollow sections with circular web openings fundamental behaviour in torsion, bending and shear. University of Nottingham, 2000; Devi et al. in J Constr Steel Res 162, 2019) have been conducted on steel members subjected to torsion. Based on the literatures, it has been concluded that perforated members have lower torsional load resisting capacity than unperforated members and square steel members are better in resisting torsional stiffness than rectangular steel members.
