Cable-stayed
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 br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extradosed Bridge
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word ''wikt:extrados, extrados'', the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external Prestressed concrete, prestressing tendons deviating upward from the deck. In this concept, they remain part of (and define the upper limit of) the main bridge superstructure. Compared to a cable-stayed or cantilever bridge, cantilever-girder bridge of comparable span, an extradosed bridge uses much shorter stay-towers or pylons than the cable-stayed bridge, and a significantly shallower deck/girder structure than used on the girder bridge. This arrangement results in the typical extradosed "look" of a fan of low, shallow-angle stay cables, usually with a pronounced "open window" region extending from the sides ...

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russky Bridge
The Russky Bridge () is a cable-stayed bridge in Vladivostok, Primorsky Krai, Russia. The bridge connects the Russky Island and the Muravyov-Amursky Peninsula sections of the city across the Eastern Bosphorus strait, and with a central span of , it is the List of longest cable-stayed bridge spans, longest cable-stayed bridge in the world. The architect of the Russky Island Bridge is Vlydskinol Ptrov. The Russky Bridge was originally built to serve the APEC 2012, 2012 Asia-Pacific Economic Cooperation conference hosted at the Far Eastern Federal University campus on Russky Island. It was completed in July 2012 and opened by Prime Minister Dmitry Medvedev, and on September 3, 2012, the bridge was officially given its name. Overview The bridge to Russky Island is the world's longest cable-stayed bridge, with a -long central Span (engineering), span.

Side-spar Cable-stayed Bridge
A side-spar cable-stayed bridge may be an otherwise conventional cable-stayed bridge, but its cable support does ''not span the roadway'', and is instead cantilevered from one side. The Esplanade Riel illustrated is located in Winnipeg, Manitoba Manitoba is a Provinces and territories of Canada, province of Canada at the Centre of Canada, longitudinal centre of the country. It is Canada's Population of Canada by province and territory, fifth-most populous province, with a population ..., Canada. This bridge is intended for pedestrian use only and has a restaurant in its base. In the example below the cable paths are aligned with the bridge centerline, so that structurally it differs only in the transfer of stresses through the tower to the foundation. The side-spar principle is not limited to a straight bridge, however. The tower could be offset and the bridge deck wrap around the spar in an arc, e.g., Chords Bridge in Jerusalem. Such a bridge would be particularly su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever Spar Cable-stayed Bridge
A cantilever spar cable-stayed bridge is a modern variation of the cable-stayed bridge. This design has been pioneered by the structural engineer Santiago Calatrava in 1992 with the Puente del Alamillo in Seville, Spain. In two of his designs the force distribution does not depend solely upon the cantilever action of the spar (pylon); the angle of the spar away from the bridge and the weight distribution in the spar serve to reduce the overturning forces applied to the footing of the spar. In contrast, in his swinging Puente de la Mujer design (2002), the spar reaches toward the cable supported deck and is counterbalanced by a structural tail. In the Assut de l'Or Bridge (2008), the curved backward pylon is back-stayed to concrete counterweights. Of this type by Santiago Calatrava * Puente del Alamillo, Seville, Spain, 1992 (backward cantilever) * Trinity Bridge, Manchester, United Kingdom, 1995 (backward cantilever) * Puente de la Mujer, Buenos Aires, Argentina, 2002 (forw ...

Dryburgh Abbey Bridge
Dryburgh Abbey Bridge was a cable-stayed bridge, cable-stayed footbridge of significant historical interest erected near Dryburgh Abbey, in the Scottish Borders, Borders of Scotland. It connected the villages of Dryburgh and St. Boswells (part of a ribbon of settlements, including Newtown St. Boswells), across the River Tweed. A crossing had existed here for centuries, originally with a ferry service. The bridge had been commissioned by David Stewart Erskine, 11th Earl of Buchan, an Eccentricity (behavior), eccentric Scottish Aristocracy (class), aristocrat who later died in Dryburgh. It was long. At the time, the cable-stayed type of bridge was undergoing a period of rapid growth in popularity. The Earl opened the completed bridge on 1 August 1817, but in January 1818 it collapsed. One of the designers, Thomas Smith, said of the collapse that due to "high wind increasing to [a] perfect hurricane, it carried off [the] chain bridge, leaving only the fastenings and supports, the ...

Brooklyn Bridge
The Brooklyn Bridge is a cable-stayed suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing of the East River. It was also the List of longest suspension bridge spans#History of longest suspension spans, longest suspension bridge in the world when opened, with a main span of and a deck above Mean High Water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915. Proposals for a bridge connecting Manhattan and Brooklyn were first made in the early 19th century; these plans evolved into what is now the Brooklyn Bridge, designed by John A. Roebling. The project's chief engineer, his son Washington Roebling, contributed further design work, assisted by the latter's wife, Emily Warren Roebling. Construction started in 1870 and was overseen by the New York Bridge Comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Puente De La Mujer
The Puente de la Mujer ( Spanish for "Woman's Bridge") is a rotating footbridge for Dock 3 of the Puerto Madero commercial district of Buenos Aires, Argentina. It is of the cantilever spar cable-stayed bridge type and is also a swing bridge, but somewhat unusual in its asymmetrical arrangement. It has a single mast with cables suspending a portion of the bridge which rotates 90 degrees in order to allow water traffic to pass. When it swings to allow watercraft passage, the far end comes to a resting point on a stabilizing pylon. Design Designed by the Spanish architect and structural engineer Santiago Calatrava on a plan very similar to a 251-metre bridge over the Guadalquivir River in Seville, Spain (1992) and a 213-metre bridge over the Sacramento River in Redding, California (2004), it has a forward-, rather than a reverse-angled cantilever, as is seen in those bridges. The bridge is the first of only two Calatrava structures in Latin America. The architect has described t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
