Steel Tank Underground Anchoring Detail to Foundation
Steel Tank Underground Anchoring Detail to Foundation
(OP)
I have steel tank buried underground. What is the best way to anchor this to foundation for uplift because it is below water table.

F.S. = weight of concrete/(buoyant force footing + buoyant force tank)
OR
F.S. = weight of concrete/buoyant force footing only

Given you're fixing the tank to the base, the uplift force is base plus tank. This can quite considerable.
Alternatively build a frame around the tank and pour concrete in when the tank is full of water (otherwise it will collapse).

In either case, the tank has to be designed for external pressure due to soil and liquid loading, and if it is very big, that becomes a problem.

since bottom of tank is flushed with top of footing, should't total bouyant force is = footing area x depth of water table x62.4 ?
i can understand, tank + footing buoyant force, if the tank has legs and not flushed with the top of footing?
