Study Notes

Properties of Metals and Construction Materials

Aluminum: Lightweight, nonmagnetic metal, excellent conductivity.
Asphalt Asbestos Protected Metal (AAPM): Asphalt coating used for weather protection on galvanized steel walls.
Cement-Asbestos Board: Noncombustible material commonly used in construction.
Glass Fiber–Reinforced Plastic: Composite of plastic reinforced with glass fibers, noncombustible and durable.

Steel Construction Components

Angle: Steel member with two legs that are perpendicular to each other.
Bar: Plate less than 6 inches wide, available in square or round shapes.
Bar Joist: Light-weight, long-span system for roof and floor support.
Box Column: Large hollow column constructed from steel plates.
Bulbtee: Beam where the end of the cutoff is thickened.
Castellated Beam: Beam altered with zig-zag cuts to increase depth and reduce weight.

Construction Systems and Techniques

Channel: Steel structural component shaped like a square "U."
Lattice Column: Vertical units linked by diagonal pieces to improve stability.
Light Gauge Steel-Framed Wall: Walls built using lightweight galvanized steel studs.
Precast Prestressed Concrete Panels: Concrete panels made off-site and delivered ready for construction.

Structural Design Elements

Spandrel Girder: Ties wall columns in a framed structure, providing horizontal stability.
Transfer Beam: Shifts vertical loads from columns to clear openings.
Waler: Horizontal beam connecting rows of soldier beams for structural integrity.

Steel Properties and Adaptations

Modulus of Elasticity: Measures steel's ability to deform and return to its original shape.
Steel Expansion Joints: Allow floor movement, accommodating temperature changes.
Tiebacks: Steel cables positioned in holes, secured with epoxy, providing additional support.

Specialized Terms and Uses

Bulkheads: Upright partitions on a ship to maintain compartmentalization for safety.
Purlins: Provide support for light-weight roofing systems.
Zee: Steel structural member with a "Z"-shaped cross section.

Fire Resistance and Insulation

Masonry Walls: Often used in unprotected steel-framed buildings for fireproofing.
Tin Ceiling: Embossed steel panel that efficiently transfers heat, often used for aesthetics.

Miscellaneous

Rakers: Diagonal columns providing structural bracing to maintain stability.
Tee: Result of cutting an I-beam lengthwise, yielding two "T"-shaped beams.
Triaged: Refers to the process of evaluating and categorizing materials based on priority.
