If 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 wall.

|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

Situation: typical nailer on top of a cmu
wall. Joists bearing on nailer and ties (H2.5) connecting joist
to nailer for uplift.
Problem: DSA (California) backcheck comment
believes that cross-grain bending of the nailer needs to be avoided
and to design direct connection to cmu wall.
I have never seen the code address cross-grain
bending in anything other than lateral anchorage of masonry/concrete
walls to diaphragms. Does the code somewhere specify that
cross-grain bending in this situation is not allowed? Any help
would be appreciated.
