The redistribution of internal forces in a beam in which the diaaonal tension crack has extended to the level of the main tension steel is discussed. It is shown that the resistance to shear of a simply supported beam without web reinforcement depends on the strength of the compression zone at the upper end of the diagonal tension crack and of the tension zone at its lower end. Accepted methods of calculation of shearing stresses give, therefore, an in-correct idea of the strength of the beam, and result in a variable factor of safety. -Different types of shear failure are described, in particular, the shear-tension failure. The influence of various factors on the shear stren concrete beams is descri th of simpl supported reinforced bed. Results of exploratory tests at the University of Manchester are discussed, with particular reference to the comparison of the strength of rectangular, T-, and L-beams. The behavior of beams loaded through secondary beams is studied on the basis of new tests.
