✦ Synopsis

A new technique, called the post-twisting technique, is suggested for concrete beams resisting pure torsion by adopting centrally placed bars with a vane arrangement, analogous to the post-tensioning system adopted for longitudinal prestressing in flexure. The efficiency and effectiveness of the present technique have been verified through experiments and it is observed that the proposed technique is more efficient than the pre-twisting technique proposed earlier on similar lines to the pretensioning method, measured by the ratio of torsional load to percentage of steel consumed.
