Design of Shallow Foundation (Isolated Footings)

Data are given:

• Column size 400mmx400mm

• Compression axial load for the load combination of (1.5 DL + 1.5 LL) is 2000 KN

• Safe soil bearing capacity at a depth of 2 meters below E.G.L is 150 kN/m²

• Assuming the self-weight of the footing and soil above it as a 10% load

• Grade of concrete=25 kN/m²

• Assuming fy=500 N/mm²

Here a sloped footing is designed.

DESGIN OF SQUARE FOOTING FOR A COLUMN 400X400 MM.

RESULT :

Provide a 3.2x3.2m footing with a depth of 500 mm.

Provide , 22 bars reinforcement of 16mm dia bars in both directions.

Provide anchorage for column and footing at 750mm.
