Talk:Cable-stayed bridge
From Wikipedia, the free encyclopedia
The biggest, or longest bridge is the one that connects Rio with Antirrio in western Greece. It is supposed to be finished today 24/5/2004 as there are only 36 meters left for the completion of the project. It will be open to the public after the Olympic Games as it has to be tested first. The bridge is cable-stayed, 2 225 meters long with four pylons. The openings are 286,560,560,560,286 meters in length. There are two approach viaducts, 392 meters on the Rio side and 239 meters on the Antirrio side. The deck is 27.5 meters wide. The foundations of the pylons go down 65 meters beneath the seabed. The seabed needed reeinforcing as it consists of clay. It can withstand impact with a tanker of 180 000 tonnes travelling at 18 knots and wind speeds of 265 kilometers per hour (winds of such speeds fall within the hurricane category)The pylons rise up to 227 meters above the seabed.
I would like to add that to the article but have insufficient data. Moreover i don´t have enough time. If anyone cares to make an inquiry i would be more than happy to help.

Jerry, sounds like that bridge needs to be its own article. Unrelatedly, I think it might be good to split the example bridges into parallel vs. radial, but I'm not sure which is which. So far, the only radial one I know of is the Clark Bridge in Alton IL, but I don't think it has a WP entry yet. Ventura 06:00, 2004 Jul 10 (UTC)
Leonard added "but the advantage of not requiring firm anchorages to resist the pull.". I figure we should following this by saying something like "For this reason cable-stayed bridges are often used when one or both ends of the gap to be spanned ends in an elevated causeway"? (or something like that) -- Finlay McWalter | Talk 23:59, 4 Aug 2004 (UTC)
Some conventional suspension bridges also end in elevated causeway on at least one end, such as the southern end of the Golden Gate Bridge and the western end of the San Francisco-Oakland Bay Bridge. In these cases, the main cables are brought down at an angle below the causeway to where it is convenient to anchor them. Leonard G. 03:23, 5 Aug 2004 (UTC)
An anonymous user changed two pillar bridge comparison to suspension bridge to seven piller. I generalized and clarified. Note that conventional suspension bridges are not built with more than two towers between anchorages due to potential dynamic instablity. (Are there any examples to the contrary?) Note that the four tower western span of the San Francisco-Oakland Bay Bridge is actually two two-tower bridges with a massive central anchorage built on pilings into hard mud.

Is there any information on the history of cable-stayed bridges? What was the first bridge built, for instance?
I have made several edits to the page, including providing a very brief history largely drawn from Walther's book (cited in the bibligraphy). I've also amended some of the terminology to reflect what is generally used in the field. If anyone has any queries or objections, please discuss them here! -- Kvetner 21:59, 16 January 2007 (UTC)
[edit] Longest in world
I note a recent edit disputed the Rio-Antirio bridge's title as longest cable-stayed bridge in the world, suggesting that in fact the Sunshine Skyway Bridge is longer. This is a bit misleading - the Sunshine Skyway bridge is mostly an elevated viaduct, with only a relatively short cable-stayed section, which seems to be in no way record-breaking. The Rio-Antirio Bridge has the longest continuous length of cable-stayed deck, and the Tatara Bridge the longest single cable-stayed span. Before I try and clarify the article (to delete the claim that the Sunshine Skyway is the "world's longest cable-stayed concrete bridge"), does anyone have any other views? -- Kvetner 13:35, 6 March 2007 (UTC)
