Torsional Behavior of Plain High-Strength Concrete Beams

Sep 01, 1990  The plain high-strength concrete beams under torsion failed suddenly and violently along a smooth surface. The skew-bending theory is found suitable for predicting the torsional capacity of plain high-strength concrete beams, provided that the splitting tensile strength is taken to represent the concrete tensile strength.

Most of the time aramid fiber is used as an externally bonded reinforcement to increase flexural and shear strength of RC beams. An attempt is made to use it for improving torsional moment carrying capacity of RC beam. Torsional failure mostly occurs in
