How to use RCC 81; Pad footing/foundation design with excel.
The excel program is very easy to understand and use. You enter data in blue cells. Part of data required include; strength of concrete and steel, bearing pressure of soil, factors of safety, proposed dimensions of pad footing and column dimensions, calculated axial loads and moments acting on the pad footing.
The program will check if pad footing dimensions chosen are suitable or not. It will even suggest pad footing dimensions that can work. You will also be able to view design status. If your design fails, it will state the reason why, so you will know which input value to adjust. When design status is valid, the program will calculate reinforcement required for the foundation footing.
