You are designing footings for a foundation on a clayey soil. Determine the required footing width considering both short term (undrained) and long term (drained) bearing capacity for the conditions given below. Base your determinations on gross allowable bearing capacity. Soil Properties: (homogeneous sandy lean overconsolidated clay) undrained shear strength, Cu = 2,100 psf drained (effective stress) friction angle, '= 25 deg. drained (effective stress) cohesion intercept, c' = 300 psf total unit weight above the water table, y = 123 pcf saturated unit weight below the water table, Ysat = 128 pcf depth to water table = 2.5 ft Foundation Information: square footing vertical column load (at ground line), Pact = 150 kips depth of embedment, D = 2.5 ft unit weight of concrete, y = 150 pcf
