12/12 Pitch Fink Truss Bottom Chord Web Joint
12/12 Pitch Fink Truss Bottom Chord Web Joint
(OP)
I'm currently looking at a fink truss with a 12/12 pitch and I have a question about the joint below:

I'm trying to determine if it makes more sense to orient the plate at this joint rotated 90 degrees for high pitch trusses 10/12 thru 12/12.
Does anyone have any pictures of this type of common joint where the plate is rotated 90 degrees. Normally the plate slots run parallel to the bottom chord for low pitch trusses.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

I can't figure out what you're trying to accomplish...

Perhaps the diagram below clarifies what I'm getting at. Is Option C a possibility from a manufacturing standpoint and plate availability?
RE: 12/12 Pitch Fink Truss Bottom Chord Web Joint
Option "B" would be the most likely that you would see on a truss design.
Option "C" - Plates that are taller than they are wide are all but unheard of.
Forces in common trusses usually aren't that large on residential projects. You won't see many 6x8 plates on web joints. (Pitch breaks joints are another matter entirely)
