Culemborg Railway Bridge
The Culemborg railway bridge (Dutch: ''Kuilenburgse spoorbrug'') is a tied-arch bridge in the Netherlands over the Lek, on the Utrecht–Boxtel railway. It held two records at the beginning: being the first important truss bridge with semi-parabolic arch and the railway-only one with the longest span in the world until 1878. Description Semi-parabolic truss bridge (1868 - 1982) For long time the construction of a bridge upon the Lek and other Dutch rivers was hindered by various difficulties, including ice melting. The decision to build a bridge upon the Lek river was eventually taken in 1863 and the architect Gerrit van Diesen was put at the head of the project. After five years, the bridge was completed and opened, together with the near railway station: it was the first great rail bridge with a semi-parabolic arch and the first important one to use the now-defined steel. At the beginning it had only one rail, but after nearly 20 years a second one was added. File:H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lek (river)
The Lek () is a river in the western Netherlands of some in length. It is the continuation of the Nederrijn after the Kromme Rijn branches off at the town of Wijk bij Duurstede. The main westbound waterway is hereafter called the Lek River. The Nederrijn is, itself, a distributary branch of the river Rhine. Portions of the river form the boundary between the provinces of Utrecht and Gelderland, and between Utrecht and South Holland. In Roman times, the Nederrijn flowed into the Kromme Rijn and these streams were the main outflow of the river Rhine. When the Kromme Rijn began to silt up in the Middle Ages, the Lek became the primary branch. A short distance past Wijk bij Duurstede, the river intersects with the Amsterdam-Rhine Canal, which continues south towards the Waal. A branch of this canal, the ''Lekkanaal'' (Lek Canal), is connected to the river in the city of Nieuwegein. Other major towns on its banks are Culemborg, Vianen, Schoonhoven, Nieuw-Lekkerland, Lekker ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Completed In 1868
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the word ''bridge' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Bridges In The Netherlands
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th c ...

Culemborg Railway Station
Culemborg () is a municipality and a city in the centre of the Netherlands, in the province of Gelderland. The city had a population of 29,386 on 1 January 2022 and is situated just south of the Lek river. Direct train lines run from the railway station towards the cities of Utrecht and Den Bosch, via the near railway bridge. Etymology The oldest example of the name is ''Culenburgh'' from 1281. Throughout the centuries several spellings have been used: ''Kulenborch'' (1305), ''Culenborgh'' (1353), ''Colemborch'' (1363), ''Culemborch'' (1472). The former part of the name (which today would be ''kuil'') refers to a hole or pit, while the later refers to the castle that was built there around 1270. History Culemborg, formerly also spelled Kuilenburg or Kuylenburgh, received city rights in 1318. Despite its Dutch character, Culemborg was not legally part of the Netherlands until the 18th century, and was instead part of a fiefdom in the Holy Roman Empire. The fiefdom (later county ...

Rust
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron. Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust. Surface rust is commonly flaky and friable, and provides no passivational protection to the underlying iron unlike other metals such as aluminum, copper, and tin which form stable oxide layers. ''Rusting'' is the common term for corrosion of elemental iron and its alloys such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called "rust". Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Other forms of rust include the result of r ...

Fatigue (material)
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting the f ...

Span (engineering)
In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramway An aerial tramway, aerial tram, sky tram, cable car or aerial cablecar, aerial cableway, ropeway, téléphérique (French), or Seilbahn (German) is a type of aerial lift which uses one or two stationary cables for support, with a third movin ...s. Span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin-jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with the strength to mainta ...
