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 ...
Longest span Arch bridge: 575 meters (Ping'nan Third Bridge, Guangxi, Southern China) Through arch bridge: Beam bridge (Integral beam bridge) [1] Log bridge (beam bridge) Viaduct: Cavity wall viaduct Bowstring arch: Box girder bridge: Cable-stayed bridge: 1,104 m (Russky Bridge, Vladivostok, Primorsky Krai, Russian Far East)
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.
Historically a beam is a squared timber, but may also be made of metal, stone, or a combination of wood and metal [1] such as a flitch beam.Beams primarily carry vertical gravitational forces, but they are also used to carry horizontal loads such as those due to earthquake or wind, or in tension to resist rafter thrust or compression (collar beam).
The span of the Pantheon, Rome, is not 43.3 m because there is a hole at the top of 9.1 m, so the span has been reduced with the size of the hole to 34.2 m. The span of any structure is measured in the following way: Place the largest possible imaginary horizontal circular disk under or inside the structure, barely touching any load-bearing ...
Longer spans, more traffic, or wider spacing of the beams will all directly result in a deeper beam. In truss and arch-style bridges, the girders are still the main support for the deck, but the load is transferred through the truss or arch to the foundation. These designs allow bridges to span larger distances without requiring the depth of ...
The 1962 built, World's Longest, Single Span, Wooden Covered Bridge at Bridgeport State Park, California, uses a Burr-Arch in combination with the Howe-Truss to achieve this over 210' span. The only maintenance a Howe truss requires is adjustment of the nuts on the vertical posts to equalize strain. [ 1 ]
The closed linear span of the set of functions x n on the interval [0, 1], where n is a non-negative integer, depends on the norm used. If the L 2 norm is used, then the closed linear span is the Hilbert space of square-integrable functions on the interval.
