Re: floor strength requirements for compact storage

Lauren Stara

Compact shelving is much heavier than standard shelving. These are standard floor loads for library stacks and compact shelving — rule of thumb for designers.

Floor loads
50 psf for office bldg
150 psf for traditional stacks
250-300 psf for high density shelving

I don’t have the exact source of these numbers at this moment but I can find it if you need a citation.

Good luck,
