I am working on a 3-story building with a 2 hour firewall that cuts right through it. The building has concrete over metal deck floors and steel beams and columns. The building is located in a high seismic region and the floor diaphragm needs to be continuous through the wall. My thought was to select a floor thickness with a 2 hour rating so that the 2 hour wall is interrupted by another 2 hour element. The wall would be attached to the deck above and below on both sides with break away clips to satisfy the structural integrity requirements of the IBC. Does that seem like a solution that would satisfy the code requirements and keep the diaphragm intact? Has anyone come up with a different solution? I would love to see a detail if you have one!
