A 400 mm concrete wall supports a dead load of 280 KN/m and a live load of 230 KN. The allowable bearing pressure is 230 KN/m2 and the level of the bottom of the footing is 1.5 m below the ground surface. Assume concrete weighs 24 KN/m3, that of soil is 15.74 KN/m3, fc’ = 20.7 Mpa, fy = 248 MPa,. Use 25 mm diameter reinforcing bars. Thickness of footing = 500 mm and concrete cover is 75 mm.
Calculate the :
(a) effective soil pressure
(b) width of wall footing
(c) spacing of bars at critical section
