How can I assume "the extension"? For spring, k=EA/L I know E and I know A and I know concrete compressive strain (0.003). The problem is L or deltaL. How can I assume those? Will L be full length or depth of member? How much will I assume delta L for it?
Thank you so much.

Try my favorite formula, the foundation for structural engineering:
Hooke's Law:
"as the extension, so the force…"

Hi,
I am modeling base plate on the 6000 psi concrete column and I want to put concrete compression only spring to represent concrete. The problem is what is the compressive spring constant of concrete. Could you help me to get it?
Thank you so much.
John
