Since it is DSA project what Steve indicated is your only option. And you
will need to check the bolt for anchorage loading.

How about a steel angle clip @ 4'oc nailed or screwed to the joist
and bolted to the masonry through the wood plate with a TITEN HD bolt?

for the replies. To clarify, this is an interior bearing wall where
the joists (TJIs) run over and bear on the nailer on the top of the cmu
know cross-grain bending is bad, but I’m just curious where in the code it
says that it is outlawed in all cases. Again, all I can find is in
reference to lateral anchorage for concrete/masonry walls to

you hang the joist from the wall with top flange hangers and put Pa straps
at bottom of joist max 4' o.c. that usually works assuming 12" deep
joist min. to get coverage around strap in cmu

Most effective method of connecting a wood
nailer(ledger) AND to avoid X-grain bending is to place two (2)
anchor bolts (staggered) within the masonry wall a distance
equal to the depth of the ledger. This will usually require a deeper
ledger than would normally be required. Eg. for a calculated 2X10
you would use a 2X12 and locate the ab's min 3" from the top and 3"
from the bottom of nailer thereby "fixing" the nailer in place and
reducing the danger of X-grain bending.
