Loosen the nuts on top of the base plate (assuming there are some). How much
can 1" of water expand as it freezes? Let's see--an inch of ice on top of a
bottle of milk. Say 1/8" from an inch of water. Just a thought.

I would like some input on the following question:
I need to know the maximum uplift pressure which could be developed due to
ice forming under a steel base plate.
Steel column on levelling nuts, very stiff heavy base plate. No grout in
place. Water collects in 1" space between underside of base plate and
concrete foundation and freezes. Need to determine maximum possible force on
anchor bolts due to ice expansion.
