  2. Structural channel - Wikipedia

    en.wikipedia.org/wiki/Structural_channel

    The structural channel, C-channel or parallel flange channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering. Its cross section consists of a wide "web", usually but not always oriented vertically, and two "flanges" at the top and bottom of the web, only sticking out on one side ...

  3. Beam (structure) - Wikipedia

    en.wikipedia.org/wiki/Beam_(structure)

    Diagram of stiffness of a simple square beam (A) and universal beam (B). The universal beam flange sections are three times further apart than the solid beam's upper and lower halves. The second moment of inertia of the universal beam is nine times that of the square beam of equal cross section (universal beam web ignored for simplification)

  4. Butler matrix - Wikipedia

    en.wikipedia.org/wiki/Butler_matrix

    This effect is called beam squint. Both the Blass matrix and Butler matrix suffer from beam squint and the effect limits the bandwidth that can be achieved. [29] Another undesirable effect is that the further a beam is off boresight (broadside beam) the lower is the beam peak field. [30] The total number of circuit blocks required is

  5. Vehicle frame - Wikipedia

    en.wikipedia.org/wiki/Vehicle_frame

    In the case of a separate chassis, the frame is made up of structural elements called the rails or beams. These are ordinarily made of steel channel sections by folding, rolling, or pressing steel plate. There are three main designs for these. If the material is folded twice, an open-ended cross-section, either C-shaped or hat-shaped (U-shaped ...

  6. Girt - Wikipedia

    en.wikipedia.org/wiki/Girt

    Channel or C section girts bolted to plate cleats welded to a portal column in an industrial building. In architecture or structural engineering, a girt, also known as a sheeting rail, is a horizontal structural member in a framed wall. Girts provide lateral support to the wall panel, primarily to resist wind loads. [citation needed]

  7. Section beam - Wikipedia

    en.wikipedia.org/wiki/Section_beam

    Section Beams are made of steel and they have a specific lengths and shapes like Ɪ-beam, 'L', C-channel and I flanged beam. These types of section are usually used in steel structures and it is common to connect them with plates of steel.

  9. Howe truss - Wikipedia

    en.wikipedia.org/wiki/Howe_truss

    Floor beams extend between the parallels of a chord and are used to support the stringers and decking. Floor beams may sit atop the chord below them, or they may be hung from the vertical posts. Floor beams generally have the greatest depth of any beam in the bridge. Floor beams are usually placed where two panels meet.
