Thanks everyone for the thoughts.
We're a west coast design firm, so seismic load path is of critical importance to our way of thinking. Having said that, we realize that there are a lot of unaccounted for strengths and stiffnesses that can be significant when compared to the demand in low...
The panel supplier changed the detail to top track of lower wall = bottom track of upper wall = bottom of metal deck.
The deck screws down to a continuous ledger track/clip system that supports the floor joists and the concrete topping runs over everything (including track)
A quick sketch...
We can get into the specifics if people are willing to join a deep dive. For now, more interested in the philosophy of using the diaphragm to satisfy the code requirement to provide or assign elements as collectors.
We have a light gauge bearing wall project in New Jersey (seismic Design Category B) with floor joists at 24" oc and 9/16" x 24 gauge decking with 1.5" light weight concrete topping.
We are the EOR, but the contractor hired a separate engineer to design the bearing walls for panelized shop...
