The
460mm
thick footing supports a
300mm
concrete wall as shown in FIGURE-2. The unit weight of the concrete is
24k(N)/()
cu.m and the unit weight of the soil is
16k(N)/()
cu.m. Use
f_(c)^(')=24MPa
and
f_(y)=240MPa
. FIGURE-2 Find the minimum width (m) of the footing to prevent uplift. Determine the minimum width of the footing if the allowable soil pressure is
200kPa
