Application
Application 1: 
Connections and supports for structural framing members that are connected to or supported on a firewall and have a fire-resistance rating less than that required for the firewall.
Exceptions:

Intent
Intent 1: 
To limit the probability that the collapse of a structural framing member attached to or supported on the firewall will lead to failure of the firewall, which could lead to the spread of fire from the building to an adjacent building, which could lead to damage to the adjacent building.
