Buoyancy Safety Factor

Buoyancy Safety Factor

Buoyancy Safety Factor

(OP)
I cannot find a code provision for a safety factor when resisting buoyancy.  Can anyone point me in the right direction?

TIA

RE: Buoyancy Safety Factor

I would think the code load combinations that reduce dead load below a factor of 1.0 would be the sort of thing you are looking for.  The dead load with a factor of less than 1 and the bouyant force still has to create a stable combination.

RE: Buoyancy Safety Factor

SF for buoyancy should be at least 1.5 - I do not know if this is from code but it's typical practice.

RE: Buoyancy Safety Factor

Search the archives.  You'll find lots of heated discussion on this topic.

I'd say it depends on what you are designing. According to Design of Liquid Retaining Concrete Structures by R.D. Anchor, "The safety margin required is a matter of judgement of the designer.  Dependent on the certainty with which the ground water level is known, the factor of safety may vary between 1.1 and 1.25."  For environmental structures, we've always used 1.15.
