A wall footing is used to support a 300 mm. reinforced concrete wall carrying a dead load of 292 kN/m and a live load of 220 kN/m. The footing has a total thickness of 450 mm. with a steel covering of 75 mm. The bottom of the footing is 1.2 m. below the final ground surface. Allowable soil pressure is 199.70 kPa. Weight of soil is 15.7 kN/m3. fc' = 27.6 MPa. fy = 276.5 MPa. Weight of concrete is 23.5 kN/m3. 4. Which of the following gives the difference between the furnished and the allowable development length of steel reinforcement at the wall footing. Use ACI Specs.
