IBC table 2306.3 - shear wall question
(OP)
In IBC-09 Table 2306.3, allowable shear for wood structural panel shear walls etc:
If I call for plywood nailed appropriately on both sides of the wall, can I double the values in the table for my allowable shear?
If I call for plywood nailed appropriately on both sides of the wall, can I double the values in the table for my allowable shear?

Typically you can double capacity in shear by sheathing both sides.

Note A: Where P2, P3, P4, or P5 panels are applied on both sides of wall, use Note B. For P2 and P3 panels on both
sides of wall, panel edges may be offset to occur on different studs in lieu of using ( 2 ) - 2 x studs per Note B.
Note B: The following items are required, at Contractors' option: ( In lieu of 3 x studs )
Stagger panel fasteners between top plates of stud wall and face nail top plates w/ 10d nails at 4" o.c
Provide ( 2 ) - 2 x studs at panel edges w/ panel fasteners staggered and face nail studs w/ 10d nails at 8" o.c
P1 is 3/8" WSP w/ 8d @ 6", P2 is 8d @ 4", etc.
P5 is 1/2" WSP w/ 10d @ 2"
So when you have P2 to P5 both sides, you need 3 x sill plate and 3 x studs unless you provide Note B.
If you have P2 or P3 you can stagger panel edges to avoid using 3 x (or double 2 x)
