4 tanks - 1 mat foundation?
4 tanks - 1 mat foundation?
(OP)
I have 4 tanks. Tanks will be full of fluid, size is 32' high and 15.5' diameter.
I'm taking over this design from another engineer.
He has 1 mat foundation for all tanks, mat size is 80' x 24'.
I'm concerned if this will cause issues with differential settlement if one or few tanks are either empty or full.
Shouldn't this be addressed in Geotech report.
Geotech report only suggests use drilled pier for large vertical loads with a bunch of formulas for drilled pier axial capacity.
I don't even know why the original design is only on mat foundation and not on deep foundation but that guy is gone now so I can't ask him.

A talk with the geotech might clear up some things.

If one tank is empty and others full- that would not generally be addressed in the soils report, other than to give you a subgrade modulus or something like that; that would be assumed to be elastic deflection, not differential settlement.
