concrete over metal deck fire rating

FIRE RESISTANCE RATINGS OF CONCRETE MASONRY ASSEMBLIES - NCMA

Concrete masonry is widely specified for fire walls and fire barriers because concrete masonry is noncombustible provides durable fire resistance and is economical to construct. Chapter 7 of the International Building Code IBC refs. 2 3 governs materials and assemblies used for structural fire resistance and fire-rated separation of .

Typically 2½ in. of concrete over the top of the deck is required for fire ratings with fireproofing on the underside of the deck. Refer to the spe-cific UL assembly or use the fireproofing manufacturer’s data to deter-mine fireproofing thickness required to meet a specific hourly rating.

Design of composite steel deck floors for fire .

Assessment of composite steel deck floors with mesh reinforcement. Composite steel deck floors consist of a profiled steel deck with a concrete topping. Included in the concrete is some light welded mesh reinforcement which acts to control cracking to resist longitudinal shear and in the case of fire to act as tensile reinforcement.

Typical concrete floor slab thickness - over metal deck and .

For an office space you require a 2 hour fire rating which means you require a 4.5" NW concrete or 3.25" LW concrete over a 2" deck. Just out of curiousity why are you not using regular beams because vibrations can often be an issue on office spaces and I am not sure how good joists are in this regard.

Concrete Fill on Metal Deck Civil Engineering

Fire Protection. Most appli ions of concrete fill on metal deck in buildings require that the floor-deck assembly have a fire rating. For noncellular metal deck the fire rating is usually obtained either by providing sufficient concrete thickness above the metal deck or by applying spray-on fire protection to the underside of the metal deck.
