  2. List of longest continuous truss bridge spans - Wikipedia

    en.wikipedia.org/wiki/List_of_longest_continuous...

    The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.

  3. 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 ...

  5. List of longest arch bridge spans - Wikipedia

    en.wikipedia.org/wiki/List_of_longest_arch...

    This list of the longest arch bridge spans ranks the world's arch bridges by the length of their main span. The length of the main span is the most common way to rank bridges as it usually correlates with the engineering complexity involved in designing and constructing the bridge. [ 1 ]

  6. List of longest suspension bridge spans - Wikipedia

    en.wikipedia.org/wiki/List_of_longest_suspension...

    The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

  7. List of longest cable-stayed bridge spans - Wikipedia

    en.wikipedia.org/wiki/List_of_longest_cable...

    Sortable list of planned and proposed bridges, ranked by length of main span Name Main span metres (feet) Status Location Notes Nie Er Bridge: 1,056 m (3,465 ft) proposed: Hainan to Guangdong China: The bridge will cross the Qiongzhou Strait, and include two 1408 metre suspension spans and several 1056 metre cable-stayed spans. [92]

  8. Deflection (engineering) - Wikipedia

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

    Building codes determine the maximum deflection, usually as a fraction of the span e.g. 1/400 or 1/600. Either the strength limit state (allowable stress) or the serviceability limit state (deflection considerations among others) may govern the minimum dimensions of the member required.

  9. Open web steel joist - Wikipedia

    en.wikipedia.org/wiki/Open_web_steel_joist

    The LH- and DLH-Series have been designed for the purpose of extending the use of joists to spans and loads in excess of those covered by Open Web Steel Joists, K-Series. LH-Series Joists have been standardized in depths from 18 inches (460 mm) through 48 inches (1,200 mm), for spans through 96 feet (29,000 mm).
