Chp. 6 building construction Flashcards
Occupancy
refers to how a building is used
Key Factos that affect fire behavior
Combustibility Thermal Conductivity Decrease in strength at elevated temperatures Thermal Expansion when heated pg. 153
Combustibility
Whether or not a material will burn determines its combustibility. Wood will ignite easily, concrete, brick and steel are non combustible materials that cannot be ignited.
Thermal Conductivity
describes how readily a material will conduct heat
Thermal Expansion
some materials-steel, in particular-expand significantly when they are heated. Steel will stretch(elongate); if it is restrained so that it cannot elongate, it will sag, warp, or twist.
Masonry
includes stone, concrete blocks, and brick
Are fire resistive
Poor Conductors of heat
Fire Wall
A wall w/ a fire-resistive rating and structural stability that separates buildings or subdivides a building to prevent the spread of fire.
Concrete
fire-resistive
does not burn or conduct heat well
low degree of thermal expansion
will not lose strength when exposed to high temperatures
Spalling
Fire may convert trapped moisture in the concrete to steam.
Chipping or pitting of concrete or masonry surfaces
