Bearing Capacity of Shallow Strip Foundations in Sand under Eccentric and Oblique Loads

Abstract

An empirical nondimensional reduction factor is proposed in this paper, which can be used for determining the ultimate bearing capacity of eccentrically and/or obliquely loaded shallow strip foundations embedded in sand. This was developed after analyzing a series of laboratory model test results available in the literature on strip foundations. The depth of foundation (D), eccentricity of load (e), and inclination of load (α)varied from 0 to 1B, 0 to 0.5B, and 0 to 20°, respectively, where B refers to the width of foundation. The proposed reduction factor was found to provide reasonably well results for calculating the ultimate bearing capacity of shallow strip foundation under eccentric and/or inclined loads. The results obtained by using the proposed method have been found to be in good agreement with widely used traditional methods available in the literature.
