Design of Shallow Foundation (Isolated Footings)

Aim:

To design a square footing for a column size of 400 x 400 with all necessary data are provided.

Introduction:

The design of square footing is to be pefromed with 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:

A simple sketch of footing is done in AutoCADD after designing the footing manually. The design procedure of the footing is attached below:

Result:

Thus the design of sqaure footing and the AutoCADD sketch is done.
