Design of Shallow Foundation (Isolated Footings)

Solution:

Aim:

To design a square footing for a column of size 400x400 using some of the informations such as

• The compression axial load for the load combination of (1.5 DL + 1.5 LL) = 2000 KN.
• The safe soil bearing capacity = 150 KN/m2 at a depth of 2 metres below E.G.L.
• Grade of concrete = M25

Then to perform the following checks:

• If the gross bearing pressure under the footing is within safe bearing capacity
• Provide sufficient depth and longitudinal steel for resisting bending and shear
• Sufficient anchorage for column steel into the footing
• If the bearing pressure at column-footing joint is within 0.45 times the maximum concrete compressive strength

Procedure:

Result:

Isolated Footing for the given loading conditions have been successfully designed.
