Cable-stayed leg is a bridge similar to suspended bridge in that it has towers and also a deck the is organized by cables, yet its cables host the deck by connecting it directly to the towers instead via suspender cables. It commonly carries pedestrians, bicycles, automobiles, trucks, and light rail. That is used in areas where spans must be longer than cantilever bridge can accomplish (because that its weight), but the expectations is quick enough for this reason a suspension bridge is not handy there economically.

Venetian inventor Fausto Veranzio was the very first to architecture cable continued to be bridges (he was additionally the first to design contemporary suspended bridge). He published his works in 1595 in his publication “Machinae Novae”. An initial built cable-stayed bridges showed up in the 19th century and many beforehand suspension bridges to be cable-stayed like footbridge Dryburgh Abbey Bridge, James Dredge"s Victoria Bridge, in Bath, England (Built in 1836), Albert leg (built in 1872) and Brooklyn leg (1883). Other early on cable-stayed bridges in the United says were Barton Creek Bridge between Huckabay, Texas and Gordon, Texas (built in 1889), bridge over Bluff Dale, Texas, (built in 1890a and also it still largely stands).

Constraction the this kind of bridge continued into the 20th century when where built “Cassagnes bridge” (designed by A. Gisclard), le Coq"s bridge at Lézardrieux in Brittany, France (designed by G. Leinekugel and also built in 1924), and also aqueduct at Tempul in 1926. Concrete-decked cable-stayed bridge over the Donzère-Mondragon canal at Pierrelatte to be designed by Albert Caquot in 1952 and also was one of the an initial the contemporary cable-stayed bridges however no various other that come after, looked up to it. Strömsund leg designed through Franz Dischinger in 1955 had an ext influence ~ above the style of the later bridges and is more often mentioned as the very first modern. Fabrizio de Miranda, Riccardo Morandi and also Fritz Leonhardt room the design pioneers that the contemporary cable-stayed bridge and also their designs had very few stay cables which was modern but resulted in greater erection costs. Later on designs have much much more cables which is much more economic in the terms of building.


A cable-stayed bridge have the right to be developed in different variations:

A side-spar cable-stayed bridge” has only one tower and is supported only on one side. One bridge built on this principle is leg in Winnipeg, Manitoba, Canada and is made to lug pedestrians. Various other is Jerusalem Chords leg which is additionally made to be bent which this design allows for. “Cantilever-spar cable-stayed bridge” has actually a solitary cantilever spar top top one next of the span. That is spar is make to withstand the bending caused by the cables due to the fact that cable forces of this bridge are not well balanced by the contrary cables and also bridge applies huge overturning pressure on that is foundation. Puente de la Mujer (2001), Sundial bridge (2004) and also Chords bridge (2008), every in Spain, are bridges the this type. “Multiple-span cable-stayed bridge” is a cable-stayed bridge with more than 3 spans. The is a more facility bridge since the tons from the main spans space not anchored earlier near the end abutments. This additionally makes structure less stiff so extr design solutions (like “cross-bracing” stays and stiff multi-legged frame towers) need to be applied. “Extradosed bridge” has stiffer and also stronger deck and its cables are linked to the deck more from the towers i beg your pardon are likewise lower 보다 those of conventional cable-stayed bridges.

Cable-stayed cradle-system Bridge” is among the newest variants. It has so dubbed “cradle system” which carries the strands in ~ the remains from bridge deck to leg deck. These cables are continuous which method that this bridge has actually no anchorages in the pylons and also its cables deserve to be removed, inspected and replaced individually.
