Factory Foundation in -50 Centigrade Environment
Factory Foundation in -50 Centigrade Environment
(OP)
I got to design a foundation system for a Freezer warehouse where the temperature will be maintained at
-50C. Can you please provide me with some design guidelines? I am a structural engineer working in Sri Lanka.

RE: Factory Foundation in -50 Centigrade Environment
I am no building engineer, but the main difference between a regular 'freezer warehouse' and the one you are describing is the greater temerature difference outside (sun) and inside (freezing)
Foundation must be strong enough to support a total construction (walls, roof, floor) able to bear/cover thicker or better insulation than 'normal'.
Special care to membranes/layers preventing condensation inside insulation.
Minus 50 deg. centigrade seems a lot, minus 25 to 40(?) perhaps more normal.

Locally, 30 yrs ago, a freezer building (with no method of keeping the underfloor materials thawed) produced a 30 foot deep frozen blob of earth under the freezer room which by expansion on freezing produced a one foot vertical displacement of the floor and by columns the roof.
