Abstract:Problems relating to shearing strength and diagonal tensile strength of reinforced concrete beams are discussed. Particular attention is given to conditions at points of contraflexure. It is pointed out that bending stresses will have an influence on both the direction of tension cracks and on the shearing strength of beams. The effect of shrinkage stresses will also have considerable influence on the diagonal tensile strength. Actual direction of cracks may cause an increase in anchorage steel tension greater than that found by ordinary bending moment theory. It is shown that the ordinary formula for shearing stresses in reinforced concrete beams is not applicable at sections where there are no bending stresses.
