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,
