Diagonal Board sheathing
Diagonal Board sheathing
(OP)
I recently got a plan check comment for using the incorrect R factor for diagonal sheathing on a wood framed house.
Am i correct in assuming I need to design for an R factor of 2.
That really seems inappropriate.

You are speaking of walls and not floor diaphragms, correct?

I don't recall seeing diagonal sheathing in buildings with aspect ratios of less than 2 having failures during seismic events.
