Determine the relative effect footing size on ultiDetermine the relative effect footing size on ultimate bearing capacity of a sand soil. Square footings bear 4 ft. below ground surface, on clay that has phi = 34 deg. and gamma = 126 pcf. Determine the ultimate bearing capacity for widths of 5, 8 and 11 ft. The groundwater table is at depth more than 20 ft below footing bearing surface. Use the Terzaghi method.Show transcribed image text
