vertical load transfer at wood floor truss bearing
vertical load transfer at wood floor truss bearing
(OP)
When using the floor truss bearing detail with a 2x band at exterior walls, how do you account for vertical load transfer. With a full-depth continuous rim the load from above is somewhat uniformly distributed to the 2-2x top plate and wall studs below. With the 2x band detail the load from above is "collected" into the ends of the trusses and is transferred onto the 2-2x top plate below as a point load. If trusses do not align with studs this can cause the 2-2x top plate to be overstressed for 2-story and larger buildings. I would appreciate hearing how some of you have handled this.

If the plates are well nailed together - you almost get a composite action - so you are looking at a section that is close to a 3.5 x 3'' deep - but maybe not quite.
Also - the chance that you will get full live load is almost impossible.
While I am not dismissing your concerns - I have have never seen this as a problem.
Good luck

1. Go to a triple plate
2. Make sure your studs and floor trusses line up. Make sure studs are fully sheathed.
3. Drop spacing to 12'' oc if necessary
