Myself and a few others did reply to you, but you simply didn’t like the answers.
In my case I suggested you talk to a structural engineer. I think the people from Karamba also said something along those lines.
The main problem is that you are reducing a very complex problem into an over simplification that is invalid.
Furthermore it seems to me that what you understand by strength is not what is defined as strength in a structural engineering framework.
Lastly the question is misplaced in a forum that is about the use of a modelling tool, not about engineering.
