Design of Shallow Foundation (Isolated Footings)

Aim: To design the square footing using the given details.

Introduction:

• Footings which are provided under each column independently are called as Isolated footings.
• They are usually square, rectangular or circular in section..
• Isolated footings are provided where the soil bearing capacity is generally high and it comprises of a thick slab which may be flat or stepped or sloped.

Procedure:

Given Column Size = 400*400

compression axial load for the load combination = 1.5 DL + 1.5 LL = 2000 KN.

SBC = 150 KN/sqm (at depth of 2 metres below E.G.L.)

Assume M25 concrete grade and Fe500

Result: Square footing is designed successfully.
