A procedure is derived for determining the ultimate bearing capacity of sand loaded uniformly through a surface, shallow or deep strip footing. The most critical slip surface was derived mathematically and the inclination of the sides of the active wedge happened to be between ø and 45 + ø/2. The latter limit will be reached when D/B exceeds the ratio 3. The method proposed in this study yielded very good results without solving any transcendental equation as in the case of Meyerhof. In addition, it clarified the effect of δ on the ultimate bearing capacity. The use of the proposed method is very simple and time saving.
