A 350mm concrete wall supports a DL = 220kN/m and LL = 145kN/m. The allowable bearing pressure is 215kPa and the bottom of the footing is 1m below the ground level. Weight of concrete is 24kN/m3 and that of soil is 16kN/m3. Thickness of the footing is 325mm with an effective depth of 250mm. a. Determine the effective soil pressure. b. Determine the required width of the wall footing. c. Determine the nominal shear stress of the wall footing.
