A square foundation is placed at a depth of 1.5 m within a sandy clay where c'=14k/m2 , phi'=23 and y=18 kN/m3 to carry a column load of 950 kN. Determine the width of the foundation that can be allowed on the foundation with a factor of safety of 3 and use the width value you have found to calculate the allowable bearing capacity(assume general shear failure and use gross values for the Terzaghi Bearing Capacity formulation for the given foundation type). If you don't write down the required equation to find the width of the foundation you cannot get credit from this question. Use the table given to you in the figure.
