Shear Panel Nail Spacing < 2"
Shear Panel Nail Spacing < 2"
(OP)
So the framer must love his power nailer because for a 10d 2" o.c. CDX plywood shear wall, he did 1.5"-2" o.c., two rows staggered on the double 2x4 chords and perimeter. The result is for many nails (in adjacent 2x4's) to be approx. 1/2"-1" apart, measured diagonally. The building department is asking for clarification if this tighter-than-specified spacing is an acceptable condition. Are there any resources out there that recommend how to apply a strength reduction factor for TOO MANY nails in a shear panel? The Doug Fir #2 studs and plywood do not show any signs of splitting, just a ton of nails.






RE: Shear Panel Nail Spacing < 2"
Now from memory (Better double check this in NDS!), I think minimum full value spacing is same as minimum full value penetration. And reduction is linear, and drops off cliff to zero at spacing equals half minimum spacing for full value. But for some reason I think reduction is linear from 100% at minimum full value spacing to 0% at 0" spacing, but is truncated at 50% spacing, such that 49% spacing is 0. I need a beer.
