Study Notes

Properties of Aluminum

Aluminum is a lightweight, nonmagnetic metal known for its good conductivity.

Definitions in Steel Construction

Angle: A steel member featuring two legs positioned at right angles to each other.
Bar: Defined as a plate less than 6 inches in width, which can be square or round.
Bar Joist: Used to create a lightweight, long-span framework for floor and roof supports.

Materials and Coatings

Asphalt Asbestos Protected Metal (AAPM): A weather-protective asphalt coating for galvanized steel walls.
Cement-Asbestos Board: A noncombustible material utilized in friable construction contexts.
Glass Fiber–Reinforced Plastic: A composite combining plastic with glass fibers for enhanced strength.

Structural Components

Box Column: A large hollow column constructed from steel plates offering support.
Bulbtee: A tee section with thickened ends used for enhanced strength.
Castellated Beam: A zig-zag cut beam welded back together to create a deeper structure.
Channel: A steel structural element with a square "U"-shaped cross section.

Construction and Insulation

Metal Panel: A prefabricated element merging thermal insulation with interior finishes.
Light Gauge Steel-Framed Wall: Constructed with lightweight galvanized steel studs, suitable for exterior walls.

Design and Engineering Terms

Modulus of Elasticity: Measures a steel's ability to distort and revert to its original shape.
Peened: Refers to a surface treatment process involving embedding material.
Rakers: Diagonal columns that provide structural bracing.

Elements in Structural Design

Spandrel Girder: Connects wall columns in framed structures; crucial for overall support.
Wide Flange Shapes: I-beams characterized by wider flanges than standard counterparts.

Miscellaneous Terms

Tiebacks: Cold-drawn steel cables inserted into holes for anchoring with epoxy.
Tin Ceiling: An embossed steel panel designed for heat transfer in both directions.

Types of Beams and Panels
