A concrete square footing is to be cast on a blinding layer to support a 400 x 300 mm concrete column. Using the following information: Base thickness h = 450 mm Axial dead load = 900 KN and axial live load = 400 KN Self-weight of the footing 150 kN (assumed) Characteristic cube strength of concrete (fcu) = 35 N/mm^2 Unit weight of concrete = 24 kN/m Steel reinforcement = 20 mm diameter The characteristic strength (fy) = 450 MPa Permissible bearing capacity of the soil = 200 kPa, and Partial material safety factor for shear = 1.4 and Cover to reinforcement = 50 mm. Determine the main steel reinforcement required for the foundation and sketch the plan and elevation of the footing with clearly marked steel reinforcement.
