versa-dek composite systems. when designed with versa-dek composite deck, versa-floor provides the shallowest unprotected fire ratings available. offered in 2 and 3.5 depth dovetail profiles. popular in mid-rise residential structures for reducing story height while maximizing ceiling height.
factory vent tabs are available as an option for formlok deck as shown in figure 2. the structural performance and fire rating of the formlok composite slab are not affected by the venting. the drying performance of concrete cast on steel deck can be expected to be similar to that of a slab cast on grade over a vapor barrier.

venting floor deck factory vent tabs are available as an option for formlok deck as shown in figure 2. the structural performance and fire rating of the formlok composite slab are not affected by the venting. the drying performance of concrete ca st on steel deck can be expected to be similar to that of a slab cast on grade over a vapor barrier.
ul design n736 is an example of a metal deck/slab on steel joists; only the joists require spray fireproofing. n737, n739, d916, d919 are examples of metal deck/slab over beams, again only the beams require fireproofing. there are other examples both using spray fire proofing and some not fireproofing the deck.

design the beams as partially composite and do not load the beam with too many studs to make it fully composite. 5 the roof will not need concrete on metal deck if there are few lightweight rtu's on the roof, in this case you may use open web joists say 2 feet on center with a standard roof metal deck.
our fire 1-hour fire rated exterior insulated metal wall and interior partition panels are factory-assembled from a unique combination of tried-and-true cladding components resulting in a building composite that delivers superior performance in all categories r and k values, long-term energy efficiency compared to less-efficient mineral wool-core sandwich panels. fire 1-hour walls are
fill over composite deck will provide a 2 hour fire resistance rating for a restrained assembly with 3/8 in. of spray-applied fire resistive material on the w8×28 test beam. the unre-strained beam rating with 3/8 in. of spray-applied fire resistive material provides a 1-hour unrestrained beam rating. a 2-hour unrestrained beam figure 2 figure 3
the fire resistance of composite floors with steel decking 2nd edition this publication describes two methods for verifying the fire resistance of composite floors. in the fire engineering method a calculation procedure is described to assess the structural performance in fire using any arrangement of reinforcement.
