  2. I-beam - Wikipedia

    en.wikipedia.org/wiki/I-beam

    For example, a "W250x33" beam is approximately 250 millimetres (9.8 in) in depth (height of the I-beam from the outer face of one flange to the outer face of the other flange) and weighs approximately 33 kg/m (22 lb/ft; 67 lb/yd). [8] I-beams are still available in US sizes from many Canadian manufacturers.

  3. Orthotropic deck - Wikipedia

    en.wikipedia.org/wiki/Orthotropic_deck

    They enhance the bending resistance of the plate to allow it to carry local wheel loads and distribute those loads to main girders. They also increase the total cross-sectional area of steel in the plate, which can increase its contribution to the overall bending capacity of the deck (i.e. the deck plate acts as a top flange in a box or I beam ...

  4. Girder bridge - Wikipedia

    en.wikipedia.org/wiki/Girder_bridge

    These create standardized I-beam and wide flange beam [7] shapes up to 100 feet in length. A plate girder is a girder that has been fabricated by welding plates together to create the desired shape. The fabricator receives large plates of steel in the desired thickness, and then cuts the flanges and web from the plate in the desired length and ...

  5. Plate girder bridge - Wikipedia

    en.wikipedia.org/wiki/Plate_girder_bridge

    In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape ...

  6. Flitch beam - Wikipedia

    en.wikipedia.org/wiki/Flitch_beam

    A flitch beam (or flitched beam) is a compound beam used in the construction of houses, decks, and other primarily wood-frame structures. Typically, the flitch beam is made up of a vertical steel plate sandwiched between two wood beams, the three layers being held together with bolts. In that common form it is sometimes referenced as a steel ...

  8. Sandwich-structured composite - Wikipedia

    en.wikipedia.org/wiki/Sandwich-structured_composite

    Sandwich theory [8] [9] describes the behaviour of a beam, plate, or shell which consists of three layers - two face sheets and one core. The most commonly used sandwich theory is linear and is an extension of first order beam theory .

  9. Girder - Wikipedia

    en.wikipedia.org/wiki/Girder

    A girder (/ ˈ ɡ ɜːr d ər /) is a beam used in construction. [1] It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web, but may also have a box shape, Z shape, or other forms. Girders are commonly used to ...
