THEORY FOR PREDICTION OF BEHAVIOUR AND BALANCED FAILURE CONDITIONS FOR REINFORCED CONCRETE BEAMS IN TORSION AND BENDING

Using the familiar skew-bending model, a general theory is developed for reinforced concrete beams in combined torsion and bending. The theory employs two equilibrium conditions and two deformation conditions. The theory is applied to predict the complete behaviour of beams up to failure, the strengths of over-reinforced and under-reinforced beams, and balanced steel ratios. Agreement between the theory and available test data is remarkably good. The paper also includes a simplified method for the calculation of strength of partially of fully over-reinforced beams. /Author/TRRL/
