Duration effects for live loads?
Duration effects for live loads?
(OP)
Since this this board is overdue for a post...
I'm figuring a wood floor for a restaurant. The live load is 100psf per code. Presumably, a large portion of that value is due to actual loading by people amassed together. Its on a 2nd floor with no elevator, so there is no possibility for the rare occasion of having a car show inside.
Is there a provision for considering the duration factor to be somewhere between the seven day and 10 minute values, since the given loading can't possibly last more than 7 days?

The load duration factor, which are allowed in the "wood" code, for live loads is 1.0......so you should just use the 100 psf.
