For school projects that have been going on I decided to make a few excel files that I think you might find useful as well.
One is to calculate the amount of rebar required in a beam or slab given a certain bending moment.
The other one will dimension a foundation footing for you based on certain parameters you give in.
Off course, all in eurocodes!
This is the rebar excel sheet (contains VBA code, but no viruses, I promise 😉 )
And this is the footing program. Again, containing VBA code.
