Theoretical behavior of HSC sections under torsion

The main purpose of this study is to propose a simple computational computing procedure in order to predict the global behavior of high-strength concrete beams under pure torsion.A computational procedure was developed and validated for normal-strength concrete beams and presented in a previous study. This procedure is revised and corrected in this article so that high-strength concrete beams can also be covered. Theoretical predictions are compared to some experimental results available in the literature.It is shown that the proposed computing procedure gives good predictions for the global behavior of high-strength concrete beams with hollow rectangle cross sections under pure torsion.
