Gypsum Shear Walls
Gypsum Shear Walls
(OP)
I believe, in older IBC guidelines, it was necessary to use (2) layers of gypsum wallboard for shear walls - (1) layer e3ach side of wood stud wall.
In the 2008 edition of ANSI / AF&PA SDPWS-2008 Wind & Seismic - Special Design Provisions For Wind And Seismic, after reading through the necessary sections of 4.3.6 Construction Requirements, I don't see a requirement for the number of gypsum wallboard layers.
Conservatively, I will use (1) layer each side of wood stud wall.
Does anyone know where I can find the requirement for number of gypsum wallboard layers? Did I miss it?
Thank you!

When using (2) layers for fire separation, what is your diaphragm attachment like? I have run into this issue on multi-level construction where the gyp needs to go to the roof deck, but there are floors that need to frame into the shearwall. Just curious how others handle this.
OP sorry for the hijack...if you want to flag for removal, I understand.

How did the framers drywall the gap between party walls? Anytime I've seen that detail it's been people laughing about how you can't sheath the faces of party walls at the gap.
I just don't see how you get the fastening correct, or tape the joints (as is required by fire code I thought).
