Theoretical and measured torsional behaviour of rectangular hollow sections.
  Theories for torsion of Rectangular Hollow Sections (RHS) are compared and thick wall theory is shown to be a better representation of behaviour. The results of torsion tests on hot-finished steel RHS are discussed and compared to the predictions of theory and finite element analysis. Although experimental measurements agree with predictions in the elastic range, measurements of torsional capacity are significantly lower than those calculated. Furthermore, there is evidence of similar behaviour in the results of torsion testing of RHS by Marshall, who developed modern simplified thick wall theory. A number of potential causes for this behaviour are examined.
