Re: 3x single studs @ abutting panels

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Nick,

This COULD work physically.

The key is what you mean by,  "nailed together."   It takes (approximately)
16-penny nails between the studs at the same spacing as the shear panel edge
nailing to adequately connect the studs for shear transfer.  Will the
carpenters remember to do this at all doubled studs?  Will the inspector
check the nailing at all doubled studs?

It seems like an area of code interpretation that could be left up to the
Building Official.  I used to allow such connections as an alternate, but
after finding too many un-connected studs during observation visits decided
to just call for 3x minimum.  Also, on heavier shear walls you're talking
about a heck of a lot of nails into edge and face of your 2x members.

The opposite extreme I have seen was a design that called for ALL studs to
be 4x's, just  to be sure that panel joints would not fall on 2x stock.  And
the shear walls still managed to get significantly screwed up.....
