Chapter 10 Noncombustible Construction Flashcards
Aluminum
A lightweight metal that is both malleable and non-magnetic. This material has very good conductivity. This non-combustible material has a low melting point and a little mass per unit of area, so it disintegrates rapidly in fire.
Angles
Steel members that have two legs at right angles to one another.
Asphalt asbestos protected metal (AAPM)
Asphalt coating that is combustible and used as a weather protective coating on galvanized steel walls.
Bar joist
A joist that generally runs in the same direction as a beam and forms a lightweight, long span system, used as floor supports and built up roofing supports.
Bars
Plates fewer than 6 inches in width; may be square or round.
Box column
A large hollow column built from steel plates.
Box girder
A large girder, which is hollow, like a box column, and often used for highway bridges.
Bulbtee
A tee where the end of the cutoff is thickened.
Bulkhead
An upright partition that divides a ship into compartments and is meant to prevent the spread of leakage or fire.
Castellated beam
A wide flange beam that has been cut in half in a zigzag pattern and then welded back together in an offset manner, creating a new, deeper beam.
Cement asbestos board
Non-combustible material often used for friable construction.
Channel
Steel construction component that has a square U-shaped cross section.
Galvanize steel walls
Walls made of weatherize steel. Can conduct heat easily.
Glass fiber-reinforced plastic
A composite material made of plastic reinforced with glass fibers.
I-beam
Beam shaped like the letter “I”.
Interstitial space
Void space made by utilizing deep parallel chord trusses.
Lattice column
Column made of vertical units connected with diagonal pieces.
Light gauge steel framed wall
An exterior wall constructed with lightweight galvanized steel studs.
Masonry walls
The most common walls for unprotected steel framed buildings; made of concrete block or a composite of concrete block and brick.
Metal panel
Prefabricated metal structure that is often made up in a sandwich construction to provide one unit combining thermal insulation and interior finish in a steel framed structure.
Modulus of elasticity
A measurement of the ability of steel to distort or restore.
Peened (peening)
Embedded into the surface.
Plates
Flat pieces of steel.
Precast prestressed concrete panels
Concrete panels that are precast and brought to the construction site.
Purlins
Beams set a right angles to trusses or roof rafters to provide support for lightweight roofing.
Rakers
Diagonal columns that brace an entire structure.
Rolled or built up members
Steel structural members; rolled members are one solid piece of metal; built up members are made up of different sections riveted, bolted, or welded together.
Spandrel girders
Girders that tie wall columns together in a framed building.
Spandrel space
Distance between the top of one window and the bottom of the one above.
Steel expansion joints
A metal connection that allows for movement of floors.
Tee
A standard I-beam cut lengthwise through the web forms two such beams with T-shaped cross sections.
Tiebacks
Cold-drawn steel cables inserted into holes driven into the rock and anchored with epoxy. Also refers to braced sheeting used in soil walls to protect against collapse.
Tin ceiling
Embossed steel; will transfer heat in either direction.
Transfer beam
Used to laterally relocate the vertical load of columns to clear an opening area.
Triage
To evaluate and categorize.
Tube
A steel structural member that is rolled in cylindrical, square, or rectangular shapes.
Waler
A horizontal beam that ties rows of soldier beams together.
Wide flange shapes
I-beams that have flanges wider than standard I-beams.
Zees
Members with a Z-shaped cross section.
