Calculate foundation
This calculator is based on the theory of André and Norsa. As we understand, this theory will calculate the force that will make the post collapse. If this happens before the foundation yields, it is a pass. If the foundation yields before the post collapses, it is a fail. (the foundation needs to be stronger).

Do you want a Plaxis calculation?
What you calculated yourself, can be checked with a finite element method called Plaxis. You'll need to feed more information such as soil class, wind, etc. You will get a report with a degree of deflection from level after 20 years. This is the most accurate method of calculating the size of a post-foundation
