A proposed industrial building will carry unfactored column loads ranging from 280 to 1,200kN and service loads from 230 to 950 kN. The allowable settlements are da = 30 mm anddDa = 12 mm. It is supported on a cohesionless sand with f′ = 35° and g = 19.2 kN/m3. Footings at this site will be at a depth of 2.2 m and the groundwater table is at 5 m.

Question
A proposed industrial building will carry unfactored column loads ranging from 280 to 1,200
kN and service loads from 230 to 950 kN. The allowable settlements are da = 30 mm and
dDa = 12 mm. It is supported on a cohesionless sand with f′ = 35° and g = 19.2 kN/m3
.
Footings at this site will be at a depth of 2.2 m and the groundwater table is at 5 m. A dilatom-
eter test run at the site has returned the following modulus profile:
Depth (m) 2 3 4 5 6 7 8 9 10 11 12 13
M (MPa) 18.3 20.6 19.0 21.1 35.2 40.0 37.3 30.1 31.9 40.0 40.8 42.0
