A 3.2 m square footing is proposed to be used to support a 373 mm x 605 mm RC column loaded with 637 kN dead load and 856 kN live load. The bottom of the footing is 1.7 m below the ground. Assume soil weighs 19 kN/m³ and the allowable soil bearing pressure is 343 kPa. The thickness of the footing is 464 mm. f'. = 21 MPa and fy = 420 MPa. It is to be reinforced with 20 mm diameter. Use 24 kN/m3 as the unit weight of concrete. Note: For two-way shear, use an effective depth measured from the top of the footing until the top of the bottom-most bar (d3) What is the ratio of the Demand Shear Force and the Capacity in Two Way Shear? (Vu/phiVn) Answer in 4 decimal places (1.6125, 1.5140, 0.8461, etc.) You Answered Correct Answer 1.3809 margin of error +/- 1%
