orthotropic deck การใช้

• Thousands of orthotropic deck bridges are in existence throughout the world.
• The roadway sits on an orthotropic deck.
• Instead, an orthotropic deck was chosen, such as the Bergs鴜sund Bridge had used.
• They were formed by a rectangular grid of flat planks, in a sort of orthotropic deck.
• It consists of spans between, with the roadway also built as an orthotropic deck with thick plates.
• Orthotropic decks permit a very shallow deck depth which reduces the steepness of approach gradients and hence their costs.
• Arches were replaced with a simple steel girder set covered with orthotropic deck, 24.4 meters wide.
• A steel orthotropic deck, steel open grate deck or a timber deck are alternatives to a concrete deck.
• The choice of a box girder bridge and the orthotropic deck were chosen because it gave the lower material use.
• The roadway lies on top of an orthotropic deck on a steel box girder, which is wide, tall and long.
• The orthotropic deck may be integral with or supported on a grid of deck framing members such as floor beams and girders.
• Resistance to use of an orthotropic deck relates mainly to its cost of fabrication, due to the amount of welding involved.
• Welded field connections are used for longitudinal and transversal joints of the cap sheet of the orthotropic deck and lower ribbed plate.
• The lateral profile of the bridge deck comprises a single box section and an Orthotropic deck inclined at 3.8 %.
• This arch deck bridge has an orthotropic deck system with total width which incorporates a two-way carriageway and a walkway at each side.
• To reduce the weight of the roadway, asphalt and concrete were removed and special steel plating ( an orthotropic deck ) was used in its place.
• The longest or record span box girder, slant-leg bridges; arch bridges; movable bridges and two Norwegian floating bridges all use orthotropic decks.
• Some very large cable-supported bridges, plus current record span ( cable-stayed bridges and suspension bridges ) would not be feasible without steel orthotropic decks.
• The Akashi-KaikyM
  Bridge's orthotropic deck allowed the Japanese to build the longest span at about 6000 ft or 50 % longer than the Golden Gate Bridge.
• Orthotropic decks have been prone to fatigue problems and to delamination of the wearing surface, which, like the deck, is also often of a very thin material to reduce weight.
