elevated bins -tanks

(OP)
A system of elevated bins, granular material, on a steel support structure.  Steel columns, bracing etc., on reinforced concrete spread footings.  It's been mentioned to me that the foundations needn't be sized for full live load (product)as the probability of all bins being full is low.  Anybody come across this, know where a live load reduction for this situation might be referenced?  Thanks.

RE: elevated bins -tanks

I agree that the probability of all bins being full at any given time is low, but I would be reluctant to apply a live load reduction factor to that situation.  

The Alberta Building Code permits a Live Load reduction factor of 0.5 + (20/A)1/2 for a storage building when the tributary area exceeds 80 m2 where A is the tributary area in square metres for the member being considered.

RE: elevated bins -tanks

Concrete is cheap, collapsed storage bins are not.  

RE: elevated bins -tanks

I'd expect to design for all-full.

RE: elevated bins -tanks

Yes, I agree with that.  Design for all bins full.
