Concrete columns strength vs footing strength
Concrete columns strength vs footing strength
(OP)
Hi All,
I was wondering if any of you are aware of a provision that limits the concrete strength for footings supporting columns (and walls) of concrete strength 10 ksi. Can I specify 3 ksi concrete footings?
Thanks.

1) Bearing checks of the wall compression block bearing on the footing.
2) Punching shear checks of the wall compression block trying to punch through the footing.
If you can make those things work with your f'c discrepancy, then you should be okay. That's a pretty big discrepancy though.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
