Bearing Wall Question / Opinions Please
(OP)
I am designing a 4,000 sf office area wholly contained inside a 10,000 square foot building. Thee office is a big box 40'x 100'. The perimeter walls will support ceiling joists only. There is a clear space between the office ceiling and the warehouse roof of around 14 feet. My questions are:
Would you design the ceiling joists for 10 PSF or 20 PSF live load?
Would you consider the walls supporting the ceiling joists to need a footing (ie saw cutting slab to provide 12" deep footing or can the wall just attach to the slab. I could check the slab for shear and I think it will probably work). The max load along a wall will be around 500plf. The slab is 5" thick, but I don't know what kind of reinforcing it has?
PS. The building within a building will be designed for seismic loads and footings will be provided at shear walls.
Thanks in advance for your opinions.

However, compared to a rack or forklift, those are light loads. And 500plf is presumably with a full live load, which that roof will never see, and most of its life there will be next to zero live load.
Agree with Triangled, this roof looks like a mezzanine and someone will want to stack crap up there. At a minimum I would put your live load very clearly on the drawings and indicate this is not designed for storage.
