Network Arch Bridge
A network arch bridge is a tied arch bridge with inclined hangers that cross each other at least twice. Structure The inclined hangers with multiple intersections make the network arch bridge act like a truss, with only axial compressible and tensile forces. Bending moments and shear forces are very small in network arches. The hanger arrangement is what separates network tied arch structures from other types of tied arches, such as those with vertical hangers. It is defined by the number of hangers, hanger inclination and hanger distance. A radial hanger arrangement provides an efficient structure, as shown by Benjamin Brunn and Frank Schanack in 2003.Brunn B., Schanack F., Steimann U., (2004) “Network arches for railway bridges”, Arch Bridges IV, Advances in Assessment, Structural Design and Construction, P. Roca y C. Molins (Eds.), , pp. 671-680, Barcelona, Spanien In the radial hanger arrangement the distances between the upper hanger nodes and the angle between hangers an ...

Novosibirsk
Novosibirsk (, also ; rus, Новосиби́рск, p=nəvəsʲɪˈbʲirsk, a=ru-Новосибирск.ogg) is the largest city and administrative centre of Novosibirsk Oblast and Siberian Federal District in Russia. As of the Russian Census (2021), 2021 Census, it had a population of 1,633,595, making it the most populous city in Siberia and the list of cities and towns in Russia by population, third-most populous city in Russia. The city is located in southwestern Siberia, on the banks of the Ob River. Novosibirsk was founded in 1893 on the Ob River crossing point of the future Trans-Siberian Railway, where the Novosibirsk Rail Bridge was constructed. Originally named Novonikolayevsk ("New Nicholas") in honor of Emperor Nicholas II, the city rapidly grew into a major transport, commercial, and industrial hub. Novosibirsk was ravaged by the Russian Civil War but recovered during the early Soviet Union, Soviet period and gained its present name, Novosibirsk ("New Siberia"), i ...

Arch Bridges
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction. A list of Roman bridges compiled by the engineer Colin O'Connor features 330 Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Siberian Times
''The Siberian Times'' is an English-language news website that was originally launched in Novosibirsk, Russia in 2012. According to the editor of the website, Svetlana Skarbo, their aim is to challenge stereotypes about the region which have been described as "negative and out of date". Former employees at East2West Limited have made accounts saying the idea for the site was formulated by Will Stewart, a British journalist who often cites it as a source in his articles. Stories from the news site are increasingly garnering the attention of the Western media. One such is an article about frozen Siberian worms becoming reanimated after thawing out of the permafrost. The story was also reported by the '' Smithsonian'' website, although a separate claim was made by the academic journal ''Doklady Biological Sciences''. Its literary style as a news source is still unknown. According to Mashable, its stories are "allegedly real with a bit of hyperbole/Siberian fan fiction thrown in". ...

The Structural Engineer (journal)
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Ordsall Chord
Ordsall Chord, also known as the Castlefield Curve, is a short railway line in Ordsall, Salford, England, which links and Manchester Oxford Road to , designed to increase capacity and reduce journey times into and through Manchester. It allows trains to run from Leeds, Newcastle and Redcar Central direct to Manchester Airport. A chord was proposed in the late-1970s and parliamentary powers for its construction were received in 1979, but the project was cancelled. Network Rail revived the proposal in 2010 as part of its Northern Hub proposal. Funding for its construction totalling £85 million was announced in the 2011 United Kingdom budget and construction commenced in 2016. It became operational on 10 December 2017. However its use since becoming operational has been limited as no additional capacity at Victoria, Oxford Road and Piccadilly has been built to cope with more through services.

Tied Arch Bridge
A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends. Description Thrusts downwards on a tied-arch bridge deck are translated, as tension, by vertical ties between the deck and the arch, tending to flatten it and thereby to push its tips outward into the abutments, like for other arch bridges. However, in a tied-arch or bowstring bridge, these movements are restrained not by the abutments but by the strengthened chord, which ties these tips together, taking the thrusts as tension, rather like the string of a bow that is being flattened. Therefore, the design is also called a bowstring-arch or bowstring-girder bridge. The elimination o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
