The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation load as concentrated load so that a solution can be reached. When the paper was presented in the conference, the audience questioned the degree of deviation of a solution obtained by such assumption. The author concur with such note. A different and more realistic approach is tried in this abstract. This approach considers the foundation load as uniformly distributed load over the area of the foundation. The results can be compared with those obtained by assuming the foundation load as a concentrated load. Such derivation can be accomplished if the effect of the uniform pressure on adjacent footings was integrated over the area of each individual footing. Bousinesq's equation can be written in the form of the equation given for an element of area dA subjected to a uniform load q.
