Question: A 75 kN column load makes an angle of 12 degree with vertical. The column load will be supported on a square footing located at depth 1 m below the ground surface. The soil beneath the footing is a clay soil which has a unit weight of 18 kN/m3, a cohesion coefficient is 20 kPa with no friction resistance. The groundwater table is located at depth 0.5 m below the ground surface. Determine the minimum footing width to maintain a factor of safety 2 against bearing capacity failure using the Vesic's method.
