A 3.4 m square footing is proposed to be used to support a 353 mm x 630 mm RC column loaded with 634 kN dead load and 853 kN live load. The bottom of the footing is 2.3 m below the ground. Assume soil weighs 19 kN/m3 and the allowable soil bearing pressure is 314 kPa. The thickness of the footing is 431 mm. f'c = 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?
