Shear Resistance of Prestressed Concrete Beams with Inclined Tendons

The results of 13 tests of post-tensioned I- and T-beams are presented. All but two of the beams contained inclined tendons and all but two failed in shear. The recommendations of the British and European Codes are reviewed and compared with the present and other test results. It is shown that the British Codes are unsatisfactory and that the CEB recommendations, while somewhat more logical, also leave much to be desired. A very simple approach to the subject is proposed, based on a truss model. The model is shown to give satisfactory agreement with experimental behaviour and ultimate strengths. H.
