I am in the middle of replacing a number of joists in a balloon framed house. The current rough cut 2×6 joists were notched over an undersized beam on one side and over the double top plate of a half wall in the walk out basement on the other side. The beam has since been replaced with 2 plies of 9 1/2″ LVL. The new 2×10 joists can be easily attached to the new beam with hangers. The other end is giving me a little trouble. See the attached drawing.
I need to provide bearing for the new 2×10 joists. My thought was to attach a ledger strip to the half wall studs for the joists to sit on. I am worried about attaching the ledger directly to the studs with no support below. I read that simpson SD screws are approved to attach ledgers to the narrow face of 2x lumber. Would this be OK?
What is the right way to provide bearing for the new 2×10 joists?
