Interior Wind Loads
Interior Wind Loads
(OP)
I am designing a large paint booth (60'x22'x21') to be located inside a large enclosed industrial building.
I read an old post on this forum that suggested that the 10 PSF minimum wind pressure (IBC 2006: 6.1.4.1) is to be used for an "indoor" structure. This seems very conservative, and I cannot find justification for it in ASCE 7 or in IBC 2006. The old Wisconsin code required a 5 PSF wind load for interior structures, which seems more reasonable, but this provision does not appear in the new codes. Because this structure is in Wisconsin and because it is very light, a 5 PSF wind load would be substantially larger than the seismic load.
What do you think? What do the codes require for an "interior" structure?

It's not really a wind load, but that seems to be a logical justification.

Timing has a lot to do with the outcome of a rain dance.

The 10 psf minimum component and cladding load is for exterior walls.

RE: Interior Wind Loads
With two adjacent bays, the windward door is open on one while the leeward door is open on the other. The partition between the two units is subjected to the full positive pressure on the windward side plus the full negative pressure on the leeward side.
In such a situation, a pressure of 5 psf or 10 psf on the interior partition would be woefully inadequate. Such a partition may be more critical than an exterior wall.
