ECCENTRICALLY LOADED SURFACE FOOTING ON SAND LAYER RESTING ON ROUGH RIGID BASE

Laboratory model-test results are given for the ultimate bearing capacity of an eccentrically loaded rough rigid strip surface footing on sand that has a rough rigid base located at a shallow depth. For centrally loaded footing, the modified bearing-capacity factors calculated from the experimental ultimate loads are compared with the existing theory as presented by Mandel and Salencon. When the ratio of the depth of the sand layer to the width of the footing is smaller than 0.6, the experimental bearing capacity is somewhat lower than that predicted by the theory by using the direct shear angle of friction. However, if the experimental variation of the bearing-capacity factor for the centrally loaded footing is assumed to be correct, Meyerhof's effective-area method may be used to estimate the bearing capacity of eccentrically loaded footing.
