Numerical Investigation of Circular and Square Hollow Steel Section Subjected to Torsion
摘要
In this research, numerical study using finite elements has been conducted on cold formed carbon circular and square hollow steel sections subjected to torsional load. The numerical analysis has been performed with the validation of experimental square section using ABAQUS software. The study has been carried out for both slender and stocky sections. The circular hollow steel section has higher resistance to torsion as compared to square hollow steel section. The stocky section had higher torsional resistance as compared to slender section. As the thickness keeps on increasing from very slender to stocky section the percentage increase in torsional resistance of circular to square section keeps on increasing.
