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
- Tee: An I-beam cut lengthwise into two "T"-shaped sections.
- Tube: A steel member available in cylindrical, square, or rectangular forms.
- Zee: A metal component noted for its "Z"-shaped cross section.
Fire Safety and Material Properties
- Aluminum is known to have a low melting point and disintegrates quickly in fire, making it a safety concern in certain applications.
