I guess that's the second point of the debate. I would consider all units as a single building and drag the forces through so that there is deflection compatibility. I'm not sure if that's what you are talking about Chuck, but it did remind me of the other method of analysis which is popular and that is to consider each unit "stand alone" but then connect them together which I disagree with.

Back when I did condo forensic work, I saw a lot of this construction. It wasn't a "code interpretation" & I would be amazed if you could talk the CBO into something else. With continuity in the roof & exterior sheathing, a little care in the LFRS design to establish stiffness compatibilty, & the units will move in phase. Treat it like a single building. You are worrying about something that probably would never happen during an event that is unlikely to happen in your lifetime. Chuck Utzman, P.E.
