An eccentrically loaded (one-way eccentricity) square foundation, given: B = 5 ft, L = 5 ft, Df = 4 ft, e = 0.5 ft, γt = 110 pcf, c’=0 and ϕ’ = 30°. Note the ground water table is at great depth below the footing. Calculate the general bearing capacity to determine the maximum allowable load that the foundation can carry using Meyerhof’s effective area method for a FS of 3.
