Buildings are designed to withstand both "live" and "dead" loads. A
"live"
load is one where the load is not constant or is moving. IE: people, wind,
etc... A "dead" load is a load that is constant or does not move. IE: the
structure itself.
So, for a 20' X 20' room in your building the
allowable load should be:
20 x 20 X 40(psf) = 16,000 lbs.
Just to point out, I believe that psf (pounds per sq foot) implies the load
should be spread out and not concentrated in one corner of the room :).
Thanks for those figures; I had always figured about 50 psf as a rule of
thumb.
