A cable-stayed bridge has one or more towers (or pylons), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.

Cable-stayed bridges found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed designs fell from favor in the early 20th century as larger gaps were bridged using pure suspension designs, and shorter ones using various systems built of reinforced concrete. It returned to prominence in the later 20th century when the combination of new materials, larger construction machinery, and the need to replace older bridges all lowered the relative price of these designs.{{Cite news|url=https://www.scientificamerican.com/article/popular-cable-stay-bridges-rise-across-u-s-to-replace-crumbling-spans/|title=Popular Cable-Stay Bridges Rise Across U.S. to Replace Crumbling Spans|last=Nordrum|first=Amy|work=Scientific American|access-date=30 April 2017|language=en}}

History

File:Pons ferrevs by Faust Vrančić.jpg polymath Fausto Veranzio, from 1595/1616. Prior to industrial manufacture of heavy wire rope (steel cable), suspended or stayed bridges were firstly constructed with linked rods (chain).]]

Cable-stayed bridges date back to 1595, where designs were found in Machinae Novae, a book by Croatian-Venetian inventor Fausto Veranzio. Many early suspension bridges were cable-stayed construction, including the 1817 footbridge Dryburgh Abbey Bridge, James Dredge's patented Victoria Bridge, Bath (1836), and the later Albert Bridge (1872) and Brooklyn Bridge (1883). Their designers found that the combination of technologies created a stiffer bridge. John A. Roebling took particular advantage of this to limit deformations due to railway loads in the Niagara Falls Suspension Bridge.

The earliest known surviving example of a true cable-stayed bridge in the United States is E.E. Runyon's largely intact steel or iron Bluff Dale Suspension bridge with wooden stringers and decking in Bluff Dale, Texas (1890), or his weeks earlier but ruined Barton Creek Bridge between Huckabay, Texas and Gordon, Texas (1889 or 1890).{{cite web

The steel-decked Strömsund Bridge designed by Franz Dischinger (1955) is, therefore, more often cited as the first modern cable-stayed bridge.

File:Abdoun Bridge (7).jpg, Amman, Jordan, example of an extradosed bridge ]]

Other key pioneers included Fabrizio de Miranda, Riccardo Morandi, and Fritz Leonhardt. Early bridges from this period used very few stay cables, as in the Theodor Heuss Bridge (1958). However, this involves substantial erection costs, and more modern structures tend to use many more cables to ensure greater economy.

Comparison with suspension bridge

File:Ada Bridge 2012.jpg at dusk in Belgrade (Serbia)]]

File:Prins Clausbrug vanuit NO bekeken.JPG in Utrecht ]]

Cable-stayed bridges may appear to be similar to suspension bridges, but they are quite different in principle and construction. In suspension bridges, large main cables (normally two) hang between the towers and are anchored at each end to the ground. This can be difficult to implement when ground conditions are poor. The main cables, which are free to move on bearings in the towers, bear the load of the bridge deck. Before the deck is installed, the cables are under tension from their own weight. Along the main cables smaller cables or rods connect to the bridge deck, which is lifted in sections. As this is done, the tension in the cables increases, as it does with the live load of traffic crossing the bridge. The tension on the main cables is transferred to the ground at the anchorages and by downwards compression on the towers.

File:Bridge-fan-cable-stayed.svg|Cable-stayed bridge, fan design

In cable-stayed bridges, the towers are the primary load-bearing structures that transmit the bridge loads to the ground. A cantilever approach is often used to support the bridge deck near the towers, but lengths further from them are supported by cables running directly to the towers. That has the disadvantage, unlike for the suspension bridge, that the cables pull to the sides as opposed to directly up, which requires the bridge deck to be stronger to resist the resulting horizontal compression loads, but it has the advantage of not requiring firm anchorages to resist the horizontal pull of the main cables of the suspension bridge. By design, all static horizontal forces of the cable-stayed bridge are balanced so that the supporting towers do not tend to tilt or slide and so must only resist horizontal forces from the live loads.

The following are key advantages of the cable-stayed form:

  • much greater stiffness than the suspension bridge, so that deformations of the deck under live loads are reduced
  • can be constructed by cantilevering out from the tower – the cables act both as temporary and permanent supports to the bridge deck
  • for a symmetrical bridge (in which the spans on either side of the tower are the same), the horizontal forces balance and large ground anchorages are not required

Designs

There are four major classes of rigging on cable-stayed bridges: mono, harp, fan, and star.{{cite web |url=http://www.eng-forum.com/articles/articles/cable_stayed.htm |title=Cable Stayed Bridge |website=Middle East Economic Engineering Forum |access-date=13 May 2016 |archive-url=https://web.archive.org/web/20190525145904/http://www.eng-forum.com/articles/articles/cable_stayed.htm |archive-date=25 May 2019 |url-status=dead }}

  • The mono design uses a single cable from its towers and is one of the lesser-used examples of the class.
  • In the harp or parallel design, the cables are nearly parallel so that the height of their attachment to the tower is proportional to the distance from the tower to their mounting on the deck.
  • In the fan design, the cables all connect to or pass over the top of the towers. The fan design is structurally superior with a minimum moment applied to the towers, but, for practical reasons, the modified fan (also called the semi-fan) is preferred, especially where many cables are necessary. In the modified fan arrangement, the cables terminate near the top of the tower but are spaced from each other sufficiently to allow better termination, improved environmental protection, and good access to individual cables for maintenance.{{Cite web|url=http://ir.lib.uwo.ca/cgi/viewcontent.cgi?article=2246&context=etd|title=Comparison Between Three Types of Cable Stayed Bridges Using Structural Optimization|last=Sarhang Zadeh|first=Olfat|date=October 2012|website=Western University Canada|format=PDF}}
  • In the star design, another relatively rare design, the cables are spaced apart on the tower, like the harp design, but connect to one point or a number of closely spaced points on the deck.{{cite book|author1=T.K.

File:Cable-stayed bridge tower arrangements.png

There are also seven main arrangements for support columns: single, double, portal, A-shaped, H-shaped, inverted Y and M-shaped. The last three are hybrid arrangements that combine two arrangements into one.

Depending on the design, the columns may be vertical or angled or curved relative to the bridge deck.

Variations

=Side-spar cable-stayed bridge=

File:Puente atirantado.PNG, joining San Pedro Garza García and Monterrey, a Cantilever spar cable-stayed bridge]]

A side-spar cable-stayed bridge uses a central tower supported only on one side. This design allows the construction of a curved bridge.

=Cantilever spar cable-stayed bridge=

Far more radical in its structure, the Puente del Alamillo (1992) uses a single cantilever spar on one side of the span, with cables on one side only to support the bridge deck. Unlike other cable-stayed types, this bridge exerts considerable overturning force upon its foundation and the spar must resist the bending caused by the cables, as the cable forces are not balanced by opposing cables. The spar of this particular bridge forms the gnomon of a large garden sundial. Related bridges by the architect Santiago Calatrava include the Puente de la Mujer (2001), Sundial Bridge (2004), Chords Bridge (2008), and Assut de l'Or Bridge (2008).

=Multiple-span cable-stayed bridge=

File:Живописный мост 2012.jpg in Moscow is a multiple-span design.]]

Cable-stayed bridges with more than three spans involve significantly more challenging designs than do 2-span or 3-span structures.

In a 2-span or 3-span cable-stayed bridge, the loads from the main spans are normally anchored back near the end abutments by stays in the end spans. For more spans, this is not the case and the bridge structure is less stiff overall. This can create difficulties in both the design of the deck and the pylons.

Examples of multiple-span structures in which this is the case include Ting Kau Bridge, where additional 'cross-bracing' stays are used to stabilise the pylons; Millau Viaduct and Mezcala Bridge, where twin-legged towers are used; and General Rafael Urdaneta Bridge, where very stiff multi-legged frame towers were adopted. A similar situation with a suspension bridge is found at both the Great Seto Bridge and San Francisco–Oakland Bay Bridge where additional anchorage piers are required after every set of three suspension spans – this solution can also be adapted for cable-stayed bridges.{{cite journal

=Extradosed bridge=

File:Twinkle_Kisogawa_bridge02.jpg

An extradosed bridge is a cable-stayed bridge with a more substantial bridge deck that, being stiffer and stronger, allows the cables to be omitted close to the tower and for the towers to be lower in proportion to the span. The first extradosed bridges were the Ganter Bridge and Sunniberg Bridge in Switzerland. The first extradosed bridge in the United States, the Pearl Harbor Memorial Bridge was built to carry I-95 across the Quinnipiac River in New Haven, Connecticut, opening in June 2012.

=Cable-stayed cradle-system bridge=

A cradle system carries the strands within the stays from the bridge deck to bridge deck, as a continuous element, eliminating anchorages in the pylons. Each epoxy-coated steel strand is carried inside the cradle in a one-inch (2.54 cm) steel tube. Each strand acts independently, allowing for removal, inspection, and replacement of individual strands. The first two such bridges are the Penobscot Narrows Bridge, completed in 2006, and the Veterans' Glass City Skyway, completed in 2007.{{cite press release

Related bridge types

=Self-anchored suspension bridge=

A self-anchored suspension bridge has some similarity in principle to the cable-stayed type in that tension forces that prevent the deck from dropping are converted into compression forces vertically in the tower and horizontally along the deck structure. It is also related to the suspension bridge in having arcuate main cables with suspender cables, although the self-anchored type lacks the heavy cable anchorages of the ordinary suspension bridge. Unlike either a cable-stayed bridge or a suspension bridge, the self-anchored suspension bridge must be supported by falsework during construction and so it is more expensive to construct.
