A shear model, the so-called “crack sliding model”, based on plasticity theory is used in this study of deep reinforced concrete beams and beams with short shear span. The study re-assesses the model by introducing a new effective tensile strength and new effectiveness factors as well as an additional contribution for taking into account the effect of the enchanced failure load for beams with short shear span. The modified model is compared with experimental results. The comparison shows good agreement between model and experiments. Furthermore, the modified model has been compared with the original model to show that the suggested new formulas in general are better for predicting shear strength than the original ones.<br/
