Abstract
This paper presents a preliminary study on the behaviour of high strength steel circular hollow sections subjected to torsion, through finite element models. A two-step validation procedure has been considered. Initially, numerical models were developed and validated against the test results, and further, the validated are used for parametric study. An extensive parametric study was conducted to study the structural performance by varying the thickness from t = 1.0 − 20 mm, considering two grades of high strength steel, namely S700 and S900. The finite element analysis results indicated a marked disparity in the deformation behaviour between slender and stocky sections. Further, a non-linear increase of ~+2100% in torque resistance for S700, while a ~+2700% for S900, is seen with the increase in thickness from t = 1.0 − 20 mm.
