Abstract:
An experimental and analytical study on the ultimate torsional strength of prestressed and reinforced concrete T-beams under combined bending and torsion without flexural shear is reported. Three modes of failure are identified and using equilibrium conditions, equations for predicting the ultimate torsional strength have been derived. The prediction equations are applicable to both the prestressed and reinforced concrete T-beams. The least of the three values has been used as the ultimate torque capacity of the beam. The validity of the prediction equations has been verified against 116 test data including the author's tests and those available in the literature.
