AISC has those handy tables for bolt groups loaded in shear with the load occuring eccentrically to the group, causing bolt rotational reactions (Instantaneous center and Elastic methods).

Suppose you have a perimeter steel beam which serves not only as a gravity beam but also as a lateral brace collector, taking axial load down its length.

I've searched through the AISC specification and the manual and cannot find a design example of this condition for the connecting plate design.

The bolts simply take a resultant shear at an angle and the tables deal OK with the bolts.  

But with the connecting plate it appears that the specification is silent unless I'm just not seeing it.  They have the bolt bearing checks (not a problem) but the shear yielding and shear/tension rupture checks don't indicate what to do with shear in two directions.
