Reinforced Concrete Pad Footing AS3600 Compliant
Title: Reinforced Concrete Rectangular Pad Footing Design
General Description: Calculates the reinforcement required for a reinforced rectangular or square concrete footing with a
rectangular or square columns at the centre of the footing, for flexure and checks 1 way and 2 way shear at the concrete column, using ductility class N reinforcement.
Limitations: For rectangular or square pads only, with no applied moment or horizontal forces
. Does not design for shear reinforcement.

Nomenclature: Symbols and notation as generally used in AS3600.
Yellow cells require data input by the designer
Geometry for the pad footing , etc
Concrete strength etc
Geometry of column etc
Applied actions and allowable bearing capacity
Area of tension reinforcement in both directions based on initial calculations and minimum reinforcement
Iterate if does not meet minimum design values
Where pink fill is used it alerts designer to options or information
Boxed cells with green background calculated automatically using formulae.
