Need help with our mezzanine and its floor capacity
Need help with our mezzanine and its floor capacity
(OP)
We are working on complying with some OSHA requirements. One of which was posting the load rating on our mezzanine.
The mezzanine is 62'8" x 93'4" x 3" thick concrete slab on metal centering.
I have been going over the prints for our building, which was built in 1997 and found where it states the live load rating as "50 psf + 20 part".
My question is, what does "+ 20 part" mean?
Thanks!

So the 20 psf is there to account for possible variations in exit way areas as well as the weights of partitions, cubicles, etc.
50 + 20 is very typical for office type floors - not adequate for storage.
