Concrete Floor Fire Resistance Rating

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?

Calculating Fire Resistance Ratings of Wood

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.

Fire Resistant Deck Material: Wood and Composite Decking

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 Mass Timber StructureCraft

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.

Dispelling the myths about structural steel and sound

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.

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.

Class A Fire Rated AERATIS PORCH FLOORING

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.

Fire Resistant Deck Material: Wood and Composite Decking

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.

Typical concrete floor slab thickness

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.

Calculating Fire Resistance Ratings of Wood

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.

Fire-Rated Systems

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.

Structural Technical Report

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.

When to Use Engineered Wood Floors

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.
