Question

4. A 6 by 6 by 24 (thick) cast-in-place reinforced concrete footing will be placed within a 20-foot thick surface layer of clayey sand. The footing will have an embedment depth of 3 feet. The soil has a cohesion of 200 psf, an internal friction angle of 28 degrees, and a moist unit weight of 116 pcf. The groundwater table is at a depth of 16 feet below grade, and there is no capillary rise. Perform a rigorous analysis to estimate the ultimate bearing capacity and allowable bearing pressure for these conditions.
