A square footing is proposed to be used to support a 465mm x 280mm RC column loaded with 950 kN dead load and 705 kN live load. The bottom of the footing is 2m below the ground. Assume soil weighs 18.5 kN/m3 and the allowable soil bearing pressure is 240 kPa. The thickness of the footing is 550 mm. f' = 28 MPa and fy = 420 MPa. It is to be reinforced with 25 mm diameter. Use 24 kN/m³ as the unit weight of concrete. Use NSCP 2015. 1. What is the smallest footing size possible? Input dimension B (in mm). Round by multiples of 10mm. For the following questions, use a square footing dimension of 3.3m 2. What is the critical wide beam ultimate shear stress in MPa? 3. What is the ultimate punching shear stress in MPa? 4. Determine the design moment of the footing, kN-m 5. Determine the total number of bars required in the footing (total for both ways)
