For thick and rigid footings, the pressure distribution under the footings is normally assumed to be linear. If uniform and symmetrical loadings are exerted on the footings, the bearing pressure is uniformly distributed. However, if unsymmetrical loads are encountered, then a trapezoidal shape of bearing reaction would result.
