Practice Problem 7.2 A 4m x 4m x 0.4m footing with a 0.4m x 0.4m column at the center is loaded with a dead load of 370 kN and a live load of 290 kN. It also resists loads acting laterally, a 95 kN dead load and a 108 kN live load. The base of the footing is 1.4 m below the ground. Unit weight of concrete is 24 kN/m^3 for concrete and 18 kN/m^3 for the soil above the footing. Use d= 315 mm for all calculations. At ultimate condition, U=1.2D+1.6L. a) Calculate the nominal shear stress in the footing at critical section for wide beam action.
