Diagonal Wood Bracing Instead of Gypsum Wall Board for Shear Resistance
I am trying to follow Prescriptive Code to get my house through permitting in Island County,WA without an engineer (the tech rat race has escaped the locked down city and made its way into the surrounding countryside, so now us regular folk have to compete with spending happy millionaires inflating prices and enticing their personal GC’s to forget about affordable, necessary housing and instead to demand that the shallow pool of structural engineers time be focused on underground swimming pools, 10′ tall quadruple sliding doors and other ego boosting moment frames that of course will only be used for 2 months of the year).
Anyway, my design has changed to easily show continuous sheathed wall panels. IRC R602.10.4.3 states that I need GWB or equivalent as the interior finish, as I don’t meet the exceptions. However, we have a mill onsite and are hoping to mill 1/2″ hemlock for interior wood paneling finish instead of GWB. The paneling will be installed vertically over horizontal, milled 2×3 chaseway (over Intello AB).
My thinking is to treat the 2×3 as Diagonal Wood Bracing DWB (45 degree angle)in the hopes that this has an in-plane shear resistance equivalent to GWB. Does anyone have any idea if this will work?
