Fire Barrier Perpendicular to Trusses
Fire Barrier Perpendicular to Trusses
(OP)
This one is a real head scratcher. I've got a single story commercial building (160'x 58', big rectangle) where the owner wants to take the last 50' feet of the building and turn it into a residence. Based on the occupancy group A-2 and R-3 I would need to call out a 2 hour rated fire barrier between the two occupancies. Instead of making thing easy and separating the last 50' of the building with the fire barrier parallel to the trusses the owner wants to leave an approximate 15' sliver of the building attached to the rest of the commercial space for storage. This would require a fire barrier constructed perpendicular to the trusses extending up to the roof diaphragm.
This seems like a bad idea just from the shear effort it would take to frame up and around all of these trusses to the roof sheathing and apply the two layers of gypsum to both sides. Furthermore the truss bottom chords penetrate the fire barrier so how does that work?
Has anyone every seen something like this?

The only reference or related item was a building review in Florida in 2005 that addresses this issue:
