Bearing capacity of strip footings subjected to complex loading

Résumé

For shallow water systems installed on a sandy soil, the load applied to the footing may be complex (i.e. inclined and eccentric) and may include cyclic effects. This paper is limited to the study of the static behavior of a soil-footing system under inclined, eccentric or complex loading. Centrifuge tests on a small scale model of a strip footing placed on a horizontal sandy soil have been performed in the LCPC laboratory (Nantes) in France. Quasi-static force-controlled load, using hydraulic servo-jack, is applied to the footing. Experimental results of the bearing capacity are compared to those given by the kinematical approach of the limit analysis theory. Also, the experimental findings concerning the footing kinematics are presented and discussed. Finally, a comparison between the reduction coefficients obtained by centrifuge model tests and those given by the limit analysis theory is presented for different loading configurations.
