ASCE
American Society of Civil Engineers
SFPE
Society of Fire Protection Engineers
Fire resistance rating
Rating assigned to material or an assembly after standardized testing, that identifies the amount of time a material/assembly will resist a typical fire as measured on a Standard time-temperature curve.
Fire stop
Solid material such as wood blocks used to prevent or limit the vertical and horizontal spread of fire and products of combustion in walls or floors, false ceilings, and in penetration for utilities, cocklofts or crawl spaces
Fire resistance directory
Published by UL, directory that lists building assemblies that have been tested and give resistive ratings
Noncombustible
Incapable of supporting combustion under normal circumstances
Masonry
Brick, blocks, stone, and concrete reinforced or us reinforced
Light frame construction
Method of constructing wood frame buildings, replaced the use of heavy timber
Fire load / fuel load
Amount of fuel within a compartment expressed in PSF, obtained by dividing the amount of fuel present by the floor area. The fire load is used to measure the potential heat release of fire within a compartment (aka fuel load)
The most significant characteristic of. Building is not its architectural style, but?
How it behaves under fire conditions
All building code classifies construction type based on what 2 attributes?
Fire resistance, determines likely hood of collapse during fire
Combustibility, combustible nature of the buildings structural system impacts rate of fire growth
What do fire resistive building provide for FF”s
Allow FF’s to aggressively attack and provide a increased degree of occupant safety
What do occupancy classifications reflect?
The differing life safety issues posed by different occupancies
From a fire protection standpoint , one of the most basic properties is what?
The degree of fire resistance e
Fire resistance is a function of?
All materials used, including combustibility, thermal conductivity, chemical composition, density, and dimensions.
Fire resistance
The ability of a structural assembly to maintain its load bearing capacity and structural integrity under fire conditions
Is fire resistive construction prone to structural failure under normal fire conditional?
It is not prone to failure under NORMAL fire conditions
In the case of “blank”, fire resistivity also means the ability to act as a barrier to fire
Walls, partitions, and ceilings
