Abstract:Results of tests on 136 simple and restrained rectangular beams, with and without web reinforcement, failing in shear were reported in Parts 1, 2, and 3 and are analyzed in this paper. From the reported tests, it was found that to predict the shear strength of a reinforced concrete beam two analytical expressions are required: (1) for the load at which diagonal tension occults form, and (2) for the load at which the compression zone of concrete is destroyed. The solution of the first problem, the cracking load equation, was obtained from test data as an empirical expression for the nominal shearing stress corresponding to the maximum shear; the second problem, the ultimate strength equation, was solved by a semi-rational expression in terms of the ultimate moment at the failure section.
