Study Notes

Aluminum

Key properties: Lightweight, malleable, nonmagnetic, low melting point, good conductivity.

Angle

Definition: A steel member with two legs positioned at right angles to each other.

Asphalt Asbestos Protected Metal (AAPM)

Usage: Combustible asphalt coating for weather protection on galvanized steel walls.

Bar

Definition: A flat steel plate less than 6 inches in width; can be square or round.

Bar Joist

Function: A lightweight, long-span system used to support floors and roofing.

Box Column

Definition: A large hollow column constructed from steel plates.

Box Girder

Application: Hollow girder primarily utilized for highway bridges.

Bulbtee

Definition: A tee shape with a thickened end on the cutoff.

Bulkheads

Purpose: Prevent leakage or fire by dividing a ship into compartments.

Castellated Beam

Creation: Made by cutting a wide flange beam in a zig-zag pattern and welding it back in an offset manner.

Cement-Asbestos Board

Use: Noncombustible material often used in friable construction for fireproofing.

Channel

Definition: A steel component with a square "U"-shaped cross section.

Galvanized Steel Walls

Characteristic: Made from weatherized steel, capable of conducting heat.

Glass Fiber–Reinforced Plastic

Definition: Composite material composed of plastic reinforced with glass fibers.

I-Beam

Shape: Resembles the letter “I,” providing structural support.

Interstitial Space

Definition: Void space created by deep parallel-chord trusses within a building.

Lattice Column

Composition: Constructed from vertical units joined by diagonal pieces.

Light Gauge Steel-Framed Wall

Definition: An exterior wall made with lightweight galvanized steel studs.

Masonry Walls

Typical Composition: Made of concrete block or a mix of concrete block and brick in unprotected steel-framed buildings.

Metal Panel

Definition: A prefabricated metal structure, often in sandwich construction, providing insulation and interior finish.

Modulus of Elasticity

Measurement: Assesses the ability of steel to distort and restore when forces are applied.

Peened

Definition: Refers to surfaces that have been hammered into a steel column or beam.

Plates

Definition: Flat pieces of steel used in construction.

Precast Prestressed Concrete Panels
