This table is based on the CRSI reinforced concrete fire resistance manual. This guide pretty much excludes me from using the 4.5" slab as a 2 hour rating by itself. Does anyone know of a UL listing of floor slab thicknesses/fire ratings. Or what fire proofing would be required to supplement the concrete flooor?
1. Describe timber-concrete composite floor systems and their use in modern mass timber buildings. 2. Review the structural design principles and processes associated with timber-concrete composite floor systems. 3. Demonstrate how timber-concrete composite floor systems can satisfy the structural, serviceability, acoustic and fire requirements of
Calculating Fire Resistance Ratings of Wood Assemblies Using the IBC. Floors must have a subfloor of at least 15/32 wood structural panels or 11/16 T and G. Roofs must have a deck of at least 15/32 wood structural panels or 11/16 T and G and finished roofing. There are quite a few additional rules for fire resistance so please ask questions.
With stay-in-place formwork, Composite TotalJoist combines the benefits of our TotalJoist system with Total-Lewis-Deck and concrete, to create a concrete floor system that is stable and feels solid. TotalJoist is our patented steel floor joist. Total-Lewis-Deck is a dovetail shaped deck with embossed ribs.

Fire Rating. Most composite decking manufacturers have fire testing data and its called a flame spread index from 0-200. Zero is the best, 200 the worst. This standard for flame spread is ASTM E84. Class A has a rating of 0-25, Class B is between 26 and 75, and Class C is 76-200.
Timber-concrete composite panels can be used as floor panels or wall panels. Either timber panels or beams can be used, and there are many methods of creating composite action between the timber and concrete. Precast vs On-site Pour. The concrete slab can be poured on-site or precast in a shop environment.
1. Concrete thickness is thickness of slab above deck, in. 3. Deck finish shall be galvanized 2. Refer to the U.L. Fire Resistance Directory for the necessary construction details. FLOOR-CEILING ASSEMBLIES WITH COMPOSITE DECK
From Table 1, an 8-in. concrete floor slab option 8 has an STC rating of 55. With option 10, a concrete floor slab on metal deck 3-in. metal deck with 3-in. concrete topping , an STC rat-ing of 51 can be achieved. Additionally, for an 8-in. hollow-core precast plank option 11 , the STC rating is 53. These options are not based on the building framing, whether steel or concrete, but on the STC rating desired.
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.
Is a fire rating important to you? For many years very few people east of the Rocky Mountains cared about how flame resistant each product was on their home. Today, however, many people are looking for the assurance a Class A fire rated product provides. The porch is an extension of the home and it is the most vulnerable to wildfires.
The only wood that really can handle fire to any significant degree is Seven Trust. If you are not already familar with this material, it is an exotic Seven Trust from South America and it is one of the hardest, toughest most insect and rot resistant wood on earth. You may also hear of claims about it having the same fire class rating as concrete.
The first question you need to ask yourself is, what is the Fire Rating on the floor or Roof. Based on the fire rating requirement, then you can start picking and chosing. The second question is do you need to use Light Weight Concrete since the latter can improve the fire rating requirement.

With option 10, a concrete floor slab on metal deck 3-in. metal deck with 3-in. concrete topping , an STC rat-ing of 51 can be achieved. Additionally, for an 8-in. hollow-core

Steel beams, load-bearing metal studs, masonry, insulated concrete block forms, and pured concrete are all compatible with STEELRITE Thinflor STEELRITE Thinflor slabs can be designed with a fire rating up to two hours. Independent sound transmission STC tests prove that STEELRITE Thinflor slabs outperform other floor systems.

Calculating Fire Resistance Ratings of Wood Assemblies Using the IBC by Sean O'Hara on November 16, 2018 Architects and Contractors can spend a lot of time hunting for miscellaneous fire rated assemblies in wood construction.
Many of these advances have changed and improved wood construction's acceptance by building codes and insurance rating agencies. Fire-Rated Systems, Form W305, is designed to bring you up to date on what are considered today among the most cost-effective fire-rated construction systems you can design or build -- wood and wood structural panels systems. This 24-page publication provides hard facts about what's available, what's acceptable, and what's best practice.
CONCRETE FLOOR/CEILING ASSEMBLIES If you are unfamiliar with UL Fire Resistance Ratings, begin with Concrete on Composite Flat Cellular, Fluted, or Blend Deck
2 The Hambro floor system has a system weight of 40 psf based on the 3 thick concrete floor and the joist weight over the 4-0 spacing. Because of the 3 thick concrete flooring, and the non- combustible nature of the steel, this system has a fire rating of 3 hrs based on Underwriter Laboratories UL testing.
Dings - The industry standard for use over wood subfloors in multifamily construction. Provides sound and fire control. Its smooth surface is ideal for finished floor goods.
Engineered wood floors were developed for use over concrete slabs, but the thicker, 3/4"-thick 2 cm versions can be nailed down over a wood subfloor, the same way you would install a plank floor. If you can save some money when youre building or renovating a frame house by buying a quality engineered wood floor, go for it.
than fire ratings obtained from fire tests. Two methods exist for determining the fire resistance of concrete walls: empirical or the more complicated analytical process. ACI 216.1-97, Standard Method for Determining Fire Resistance of Concrete and Masonry Construction Assemblies, pro-vides a simplistic empirical method for
The fire resistance rating for a floor/ceiling assembly is obtained from the protection provided by the ceiling, in combination with the slight fire resistance of the lightweight wood floor structure.
The result is a composite floor system having a sound transmission class STC of 57 with the addition of a gypsum board ceiling. Fire resistance ratings of up to three hours are easily achieved with the Hambro Composite Floor System by the installation of a gypsum board ceiling directly under the joists.
