Diagonal sheathing
Diagonal sheathing
(OP)
IBC 2006 is governing code. It appears that diagonal DF sheathing is allowed and it will make my required value. Where could I find construction details?

RE: Diagonal sheathing
I don't have time to verify that - but that's where it should be - if it exists...
RE: Diagonal sheathing
4.2.7.2 for Diaphragms
4.3.7.5 for shear walls
RE: Diagonal sheathing
Section 2306.3.3 through 23063.5 & Table 2306.3.3 outline the details and shear capacities for diaphragms and 2306.4.2 addresses shearwalls.
But, if this is new construction I would suggest that you use wood structural panels (Plywood or OSB). The panels cost less for materials & labor for the same allowable strength and provide more structural integrity to the overall lateral force resisting system.
RE: Diagonal sheathing
I am acquainted with the capacities for shear walls and diagonal sheathing and the associated tables.
I am looking for construction details. Maximum spacing on the studs for the diagonal sheathing. Or are you telling me the diagonal sheathing construction requirements are the same as for panels?
The 1x8 sheathing is going in per architect. I was hoping to not have to back the 1x8 with plywood.
RE: Diagonal sheathing
I suggest that you review the write-up in Section 4.3 Wood Shearwalls in the AF&PA's Special Design Provisions for Wind & Seismic Supplement. I only have the 2001 Edition but in section 4.3.7.5 it notes that diagonally sheathed single layer of lumber shearwalls are permitted in Seismic Design Categories A,B,C & D. I don't see anything about stud spacing with this layout of diagonal sheathing.
I think that you can get to a pdf of the Supplement from the AF&PA's web site which is www.awc.org
I hope that this helps.

If you can't locate a copy of the WWUB, you could contact the Western Wood Products Association for information.
