A square column 449 mm x 449 mm rests on a square footing. The column supports a dead load of 1,039 kN and a live load of 830 kN. The soil bearing capacity is 254.26 kPa. The base of the footing is 1.57 m below the ground. Assume unit weight of concrete of 24 kN/m3 and unit weight of soil of 16.6 kN/m3. The footing has a thickness of 597 mm and the centroid of the main bars is 100 mm from the bottom of the footing. Use fc’ = 24.4 MPa, fy = 248 MPa. Calculate the number of required number of 16 mm ϕ bars Note: Present the width (B) in multiples of 100 mm
