IBC 2015
4 story office building
Type 2A (1-hour rated floors)
8' x 30' Opening in floors 2, 3 and 4
glass handrail around the openings
I am looking at a horizontal shutter that will close the opening between floors 2 and 3 when smoke/fire alarm sounds. The horizontal shutter would affectively negate the smoke requirements of a 4 story atrium. The horizontal shutter meets UL10B. However it is NOT a 1-hour fire rated shutter and I think IBC Section 712.3 fits into the argument here.
Design Intent:
Do not want smoke evac system. Would like a 4 story visual opening.
Anyone with any thoughts?
Thanks
