Abstract:
Classical theory shows that both torsion and flexural shear have the same point of maximum stress for rectangu-lar sections. However, the stress distribution throughout the test of the cross section varies significantly. A series of rectangular reinforced concrete beams with normal percent-ages of both longitudinal and transverse steel was tested and the interaction of their torsional and flexural shear capacities was developed. The effects of bending and amount of reinforcement are discussed. Various interaction formulas are compared.
