Live load for museum floor 2

[Lutfi]

I can not find direct reference for second floor live loading of a photography museum. Does anyone have a reference that they can cite for me?

I am between two values, 50 PSF and 80 PSF. Any thoughts would be appreciated.

I vote for 100 psf. Museums often change hands and function - one day photos the next sculptures, etc. Forklifts are common and not all operators are pros. I was working in the Guggenheim, NY, when a 36 W 350 was dropped on the spiral ramp during installation of a sculpture.
