Given the following:
Column: 600 mm x 600 mm
Axial Dead Load = 1680 kN
Axial Live Load = 1350 kN
Depth of footing = 1.8 m
Allowable soil pressure = 230 kPa
Unit weight of soil above footing = 16 kN/m 3
Unit weight of concrete = 24 kN/m 3
fc' = 28 MPa
fy = 345 MPa
Design the footing if its width is limited to 3.2 m. Use 25 mm bars and 75 mm clear concrete cover. Use load factor of 1.4 DL + 1.7 LL.
