A square column 393 mm x 393 mm rests on a square footing. The column supports a dead load of 1,124 kN and a live load of 848 kN. The soil bearing capacity is 301.6 kPa. The base of the footing is 1.72 m below the ground. Assume unit weight of concrete of 24 kN/m³ and unit weight of soil of 16.14 kN/m³. The footing has a thickness of 632 mm and the centroid of the main bars is 100 mm from the bottom of the footing. Use fc' = 26.44 MPa, fy = 248 MPa. Calculate the number of required number of 16 mm ¢ bars
