k - subgrade reaction
k - subgrade reaction
(OP)
Hopefully this is an easy one.
I haven't seen this written anywhere, making me doubtful, but it seems that there be a strong correlation between k and f'c, if the subgrade is concrete. (in my case, the "foundation" is the plain concrete within a dam) In fact, it seems like I should use f'c as k.
Am I missing something, or is this as simple as I'm thinking it is?

There are also problems formulated for a semi-infinite solid, and you should be able to get an idea of the local deflection from that type of formulation. Roark's Formulas for Stress and Strain may have info on that topic. I've seen it somewhere!
If bearing is very high, also check ACI 318 for bearing pressure limitations (which is based on fc', but not related to deflection).
