The effect of shear on the ultimate moment of resistance of rectangular beams was investigated with the aid of small scale reinforced plaster beams. The modes of failure are defined and classified. A hypothesis is developed that the effect of shear simply reduces the potential moment of resistance below that which would be developed in pure flexure. This hypothesis forms the basis of a simple method of predicting the ultimate load and mode of failure from the known bending moment and shearing force diagrams for any beam. It is checked by the results of experiments on beams under distributed buted load. Results of the experiments are compared, where possible, with those obtained on reinforced concrete beams and published by other investigators.
