Cable-stayed Bridges By Country
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 were being designed and constructed by the late 16th century, and the form 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-staye ...

Russky Bridge
The Russky Bridge (russian: Русский мост, ''Russian 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 longest cable-stayed bridge in the world. The Russky Bridge was originally built to serve the 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. The bridge also has the second highest pylons after the Millau Viaduct and the longest cable stays. The design of the bridge crossing has been determined on the basis of two primary factors: *Shortest coast-to-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Dryburgh Abbey Bridge
Dryburgh Abbey Bridge was a cable-stayed footbridge of significant historical interest erected near Dryburgh Abbey, in the 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 eccentric Scottish 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 described the collapse due to "high wind increasing to perfect hurricane, it carried off chain bridge, leaving only the fastenings and supports, the work of half a year, demolished in an hour...." After a redesign, a replacement was built, but th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Republic Of Venice
The Republic of Venice ( vec, Repùblega de Venèsia) or Venetian Republic ( vec, Repùblega Vèneta, links=no), traditionally known as La Serenissima ( en, Most Serene Republic of Venice, italics=yes; vec, Serenìsima Repùblega de Venèsia, links=no), was a sovereign state and Maritime republics, maritime republic in parts of present-day Italy (mainly Northern Italy, northeastern Italy) that existed for 1100 years from AD 697 until AD 1797. Centered on the Venetian Lagoon, lagoon communities of the prosperous city of Venice, it incorporated numerous Stato da Màr, overseas possessions in modern Croatia, Slovenia, Montenegro, Greece, Albania and Cyprus. The republic grew into a Economic history of Venice, trading power during the Middle Ages and strengthened this position during the Renaissance. Citizens spoke the still-surviving Venetian language, although publishing in (Florentine) Italian became the norm during the Renaissance. In its early years, it prospered on the salt ...

Pons Ferrevs By Faust Vrančić
The pons (from Latin , "bridge") is part of the brainstem that in humans and other bipeds lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum. The pons is also called the pons Varolii ("bridge of Varolius"), after the Italian anatomist and surgeon Costanzo Varolio (1543–75). This region of the brainstem includes neural pathways and tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus.Saladin Kenneth S.(2007) Anatomy & physiology the unity of form and function. Dubuque, IA: McGraw-Hill Structure The pons is in the brainstem situated between the midbrain and the medulla oblongata, and in front of the cerebellum. A separating groove between the pons and the medulla is the inferior pontine sulcus. The superior pontine sulcus separates the pons from the midbrain. The pons can be broadly divided into two parts: the basilar part of the pons (ventral p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brooklyn Bridge
The Brooklyn Bridge is a hybrid 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 longest suspension bridge in the world at the time of its opening, 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, which eventually led to the construction of the current span, 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, with the Tammany Hall-controlled New York Bridge Company overseeing construction, although nume ...

Cantilever Bridge
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beam (structure), beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Civil engineer, Engineers in the 19th century understood that a bridge that was continuous across multiple supports would distribute the loads among them. This would result in lower stresses in the girder or truss and meant that longer spans could be built. Several 19th-century engineers patented continuous bridges with hinge points mid-span. The use of a hing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
