A rectangular footing is to be used to support a 300 x 400 (400mm side is parallel to the long dimension of the footing) column loaded with 420 kN dead load and 540 kN live load. One side of the footing is 4.0m. Use effective soil pressure of 70 kPa. F'c = 35 MPa and fy = 420 MPa. Use minimum steel ratio for longitudinal bars as 0.0018.
