2. Timeline of three longest supported deck arch bridge spans

   en.wikipedia.org/wiki/Timeline_of_three_longest...

   New River Gorge Bridge has the longest free span of all deck arch bridges: 518 m. This is the timeline of the 3 longest supported deck arch bridge spans in the world, where the road deck lies on top of the arch. The deck is supported by columns, truss, rubble or lies directly on the arch. These bridges are often found in narrow valleys.

3. Open web steel joist - Wikipedia

   en.wikipedia.org/wiki/Open_web_steel_joist

   The main function of an OWSJ is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to the structural frame i.e. beam and column. In order to accurately design an OWSJ, engineers consider the joist span between bearing points, joist spacing, slope, live loads , dead loads , collateral loads, seismic ...

4. Pier (bridge structure) - Wikipedia

   en.wikipedia.org/wiki/Pier_(bridge_structure)

   In this case, the height of the structure, measured between the top of the deck and the ground, is between the values a/3 and a/2, where a denotes the span of the arch, which is generally a semicircular or elliptical arch. [7] The thickness e of the pier depends solely on the span of the arches: a/10 < e < a/8.

5. Deck (bridge) - Wikipedia

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

   A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. 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.

6. Span (engineering) - Wikipedia

   en.wikipedia.org/wiki/Span_(engineering)

   In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...

7. 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. Double tee - Wikipedia

   en.wikipedia.org/wiki/Double_tee

   The first building with all pre-stressed concrete columns, beams, and double tees was a two-story office building in Winter Haven, Florida, designed and built in 1961 by Gene Leedy. Leedy experimented when building his architectural office by using structural elements of prestressed concrete and designing the new "double-tee" structural elements.
