Effect of the eccentric load on the bearing capacity of a strip footing founded on sand
Abstract
The finite differences FLAC 2D software which allows to model all soil-structure interactions regardless of the difficulty of the problems is used to determine the bearing capacity and stress distribution under a rigid strip footing submitted to vertical centered and eccentric loads. The footing is set on a free surface of sand with no surcharge applied. The soil is assumed to be elastic – perfectly plastic following the Mohr–Coulomb failure criterion. The results of the present study show that the conception proposed by Meyerhof tends to underestimate the bearing capacity, especially for large eccentricities. The study proposes an expression of the effective width that gives reasonable bearing capacity values, even for large eccentricities.
