Design of Shallow Foundation (Isolated Footings)

1)

Given:

• Column size= 400x400 mm
• SBC=150 KN/mm2
• Compression axial load=2000KN
• Fck=M25

Steps to design a square footing:

• Size of footing
• Net upward pressure
• Bending moment
• Depth of footing
• Reinsforcement
• One way and two way shear

One way shear check:

Two way shear check:

Result:

Using the given details the square footing has been designed.
