SITUATION. A square footing is to support a 400 mm x 400 mm column carrying 1400 kN live load and 1200 kN dead load. The allowable soil pressure is 250 kPa. The bottom of the footing is situated 1 m below the ground surface. Assume the average unit weight of soil and concrete is 19 kN/m3. For footing, use fc' = 21 MPa and for column, use fc' = 28 MPa. For all steel bars, fy = 414 MPa. 4. Determine the number of 28 mm dowel at the base of the column.
