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 ...
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]
The same structural effects are also true of the concrete slab in a composite girder bridge, but the steel orthotropic deck is considerably lighter, and therefore allows longer span bridges to be more efficiently designed. Resistance to use of an orthotropic deck relates mainly to its cost of fabrication, due to the amount of welding involved.
Construction of the bridge began in fall 2018 and construction on the bridge deck began in December 2022, with the opening timeline delayed amid the COVID-19 pandemic. The bridge deck was ...
Falsework parallel truss bridges temporarily supporting deck segment box structures Overpass under construction over Interstate 5 in Burbank, California, in July 2021 [4] [5] Sixth Street Viaduct Falsework - Bent 11 Jump Span. Shown in the background is a concrete Y-Arm.
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.
A concrete girder bridge pier during construction prior to installation of the bridge deck and parapets, consisting of multiple angled pylons for support (bottom), a horizontal concrete cap (center), and girders (top) with temporary wood bracing. The substructure is made of multiple parts as well:
The bridge structure comprises 18 structural steel bridge decks, 20 structural steel masts and 16 horizontal spars [citation needed] or in layman's terms horizontal masts. 72 precast concrete deck slabs sit on the main bridge deck and are secured to the steel structure and together by in-situ concrete stitch pours [citation needed].
