Shear in reinforced concrete beams

Generally acceptable compatibility and ultimate strength precepts are used in this paper to establish a physical theory of shear in reinforced concrete. Account is taken of the shear resistances of both un cracked concrete and shear reinforcement. The theory is used as the basis for the development of a simpler, but still analytic rather than empirical, design method, and the adequacy of the accuracies of both the basic and the simplified approaches is established by comparison with more than a thousand published test results.
