Liquor Warehouse Live Load....
Liquor Warehouse Live Load....
(OP)
Alrighty, now that I've got your attention!
Seems to be a little disagreement between the architects and the engineers. Arch. propose a mezzanine for a liquor store is 125 psf, and us engineers think 250psf is the more appropriate live load.
I've calculated that 12oz. beer cans (full) per cubic foot weigh 42 pcf. Stacked 8 feet high is 336 psf. Obviously you cant stack cases of beer solid on a mezzanine - you need pathways to access this beer. So it would seem that the 250 psf would be appropriate.
A penny for your thoughts.

the heavy liquid adds up in hurry! I would figure the height of the shelf and how much liquor can be stacked. Then I would use density of water to compute total weight. Then I would divide by mezzanine area and she what you come up. I would use the heaviest load which is conservative.

I would go a few steps further:
1. Be sure in your calculation of 336 psf that you account for pallet spaces, rack legs causing gaps in the product, etc. - otherwise you are way too conservative.
2. Determine a two-tiered approach. Directly under the product you will have the heaviest weight. In the aisles you will have product plus whatever moves that product plus the guy moving the product. The larger support members such as girders and some beams taking large tributary areas will support an average of these loads while your deck slab, or smaller spanned beams may take a smaller, and heavier concentration.
3. In other words, there's nothing that requires you to come up with just one number for live load here. Use your wits and account for the spaces, tributuary areas, and max./min. loads that will actually occur.
Finally, I'm not advocating a "nat's-ass" precision here, just some common sense - 336 psf is a pretty big load to apply to an entire floor.

What happens when they stock up for Christmas and decide to just pack the whole area solidly? Or use it for temporary storage the day a big load gets delivered.
Also depending on the structural system, don't forget that the worst loading situation can be when every second bay is loaded.
