Vertical Uplift Capacity of Horizontal Anchors
The method of characteristics coupled with a log‐spiral failure surface was used to develop a theory for vertical uplift capacity of shallow horizontal strip anchors in a general soil. Uplift‐capacity factors , and , for the effects of cohesion, surcharge, and density, respectively, have been established as functions of embedment ratio and angle of friction . The extent of the failure surface at the ground has also been determined. Comparisons made with existing test results support the predictive capability of the theory, and comparisons with the analysis proposed by Meyerhof and Adams show the proposed analysis provides slightly more conservative predictions of pullout capacity.
