  2. Deck (bridge) - Wikipedia

    en.wikipedia.org/wiki/Deck_(bridge)

    If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck. A beam and slab deck is one where the beams may deflect somewhat independently, and any transverse forces are carried in the deck. A cellular deck is one where a number of thin slabs and webs will ...

    en.wikipedia.org/wiki/Orthotropic_deck

    The original concrete deck of the 670 m (2,200 ft) North Viaduct of the Lions Gate Bridge was replaced with a lighter and wider orthotropic deck, carried out in sections using a series of short closures of the bridge. [3] Cantilever orthotropic decks allowed the Tamar Bridge to remain open whilst the main deck was replaced in 1999. An ambitious ...

    The transverse deck support members function as deck girders. Width out-to-out is 23'-2", curb-to-curb is 21 feet. The unique design allowed the bridge to span both the falls and a nearby lumber company's log flumes." [2] "Cattle pass" Near Bridal Veil Falls. This cattle creep consists of a single 8-foot reinforced-concrete deck slab span. "A ...

    en.wikipedia.org/wiki/Duckabush_River_Bridge

    The deck slab is hung by suspenders from the pair of arch ribs and acts as a tie. As with a steel arch bridge, the two arch ribs of the Duckabush River Bridge were connected by three struts to provide lateral rigidity against traffic and wind loads. The Duckabush River Bridge is one of five concrete tied arches within the State. [2]

  6. Girder bridge - Wikipedia

    en.wikipedia.org/wiki/Girder_bridge

    The deck is the roadway or walkway surface. In roadway applications it is usually a poured reinforced concrete slab, but can also be a steel grid or wood plank. The deck includes any road lanes, medians, sidewalks, parapets or railings, and miscellaneous items like drainage and lighting.

    In the United Kingdom, the method developed by Kirkpatrick, Rankin & Long [15] in 1984 and substantiated by testing a full-scale bridge in 1986 [16] first led to the introduction of new rules for the economic design of reinforced concrete beam and slab bridge decks in Northern Ireland. [17]

  8. Plate girder bridge - Wikipedia

    en.wikipedia.org/wiki/Plate_girder_bridge

    In the deck-type bridge, a wood, steel or reinforced concrete bridge deck is supported on top of two or more plate girders, and may act compositely with them. In the case of railroad bridges, the railroad ties themselves may form the bridge deck, or the deck may support ballast on which the track is laid.

  9. Beam bridge - Wikipedia

    en.wikipedia.org/wiki/Beam_bridge

    Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
