Re: OSB Shear wall nailing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
My understanding is if the sheathing panel has an "APA Rated Sheathing, PS-1" stamp on it, you can use the higher shearwall values, regardless if it's plywood or OSB.  If it's not stamped, and picked up from the Depot, then it's likely considered "other."  Therefore, the lesser values apply.  GL.

Are the Shear wall tables directly applicable to plywood and OSB and where can this association be found in the code or other documents.  IBC 2306.4.1 says structural panel sheathing.  Does "structural panel sheathing" indicate both plywood and OSB?  It has been a very long time since I have been asked this and I am going to have to explain. 


Buddy, are you out there?
