Top Plate & Trusses
Top Plate & Trusses
(OP)
I have a situation where the truss does not coincide with a stud. The truss bears midway between two studs. There is a double top plate. The wood species is SPF no. 2 or btr. The additional stud interferes with insulation. Is there any way that this works? Can the load be assumed to transfer into the plywood sheathing (sheathing will be present prior to truss erection) to account for some extra capacity?

What is the truss spacing and stud spacing?
Residential trusses at 24" o.c. don't always line up with studs at 16" o.c., and that's what the double top plate is for.
I'm guessing this must be a heavy truss application or I must be missing something with the original post?

I know that is what the double top plate is for. I ran the numbers for SPF no.2 or btr as the top plate and some typical reactions from the trusses.

I personally wouldnt rely on the sheathing to provide support since the sheathing is only on one side.
If you're worrying about the top plate span, how about the single bottom plate span across the floor joists? Did you check that or provide blocking between joists?
