Use the effective area to calculate the bearing capacity Q u = quA' = quB'l' The concept of effective area can be applied to circular footings and 2-D eccentricity. These problems are solved for effective dimensions so that the resultant load acts at the centroid of the effective area. (This is true of the above 1-0 problems which are much easier to calculate.) For clays (cjl = 0) the bearing capacity decreases linearly with e. For sands (c = 0) the effect is parabolic. See next page....
