RE: wood framing question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
This would not be a problem since the purpose of the double top plate is to create continuity for drag along the continuous length of plate. The 4'-0" overlap is generally acceptable for most chord forces unless you have a very high aspect ratio with a shallow depth diaphagm that would allow the tensile force to exceed the capacity of the 16d nails used in the splice.
A third plate would act in the same manner as simply installing a strap at the discontinuity where the splices are not sufficiently long to meet minimum code requirements (Conventional framing).
Therefore, you have to options. First install the third plate assuring that you have sufficient splice lengths at each plate splice below, OR analyize the chord force at each discontinuity to verfy if what was actually done can be justified or if you can replace the discontinuity with a light gauge strap - a less drastic measure than raising the plate heights by 1-1/2".
Hope this helps

Does any body have any misgivings about triple top plates (2x6) as opposed
to dbl top plates for a bearing wall ? I am thinking of the perpindicular
to plane force transfer. The framer screwed up on the length of the studs
and he wants to make up the diff. by adding another plate.
