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.
