Freyssinet Test Arch
The Freyssinet Test Arch (in French ''Arche d'essai Freyssinet'') is a prestressed concrete arch built in 1909 in Moulins, Allier by Eugène Freyssinet1. Its purpose was to test the resistance of this material to traction exerted on very flat and long-range arches. Freyssinet wanted to validate this prestressed concrete technique which he had perfected before the construction of three road bridges over the Allier river which he was to undertake in the following years: the , the and the Châtel-de-Neuvre bridge. As the first testimony to this innovative technique, the arch has been registered as a Monument historique ''Monument historique'' () is a designation given to some national heritage sites in France. It may also refer to the state procedure in France by which National Heritage protection is extended to a building, a specific part of a building, a coll ... since October 2021 with Boutiron Bridge, the only existing original bridge of the three.

Moulins, Allier
Moulins (; oc, Molins) is a Communes of France, commune in central France, capital of the Allier Departments of France, department. It is located on the river Allier (river), Allier. Among its many tourist attractions are the Maison Mantin, the Anne de Beaujeu Museum and The National Center of Costume and Scenography. Geography Moulins is located on the banks of the river Allier. History Before the French Revolution, Moulins was the capital of the provinces of France, province of Bourbonnais and the seat of the Duc de Bourbon, Dukes of Bourbon. It appears in documented records at least as far back as the year 990. In 1232, Archambaud VIII, Sire de Bourbon granted a franchise to the village's inhabitants. The town achieved greater prominence in 1327, when Charles IV of France, Charles IV elevated Louis I, Duke of Bourbon, Louis I de Clermont to Duke of Bourbon. Either Louis or the later Peter II, Duke of Bourbon and Duke of Auvergne, of Auvergne moved the capital of the provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugène Freyssinet
Eugène Freyssinet () (13 July 1879 – 8 June 1962) was a French structural and civil engineer. He was the major pioneer of prestressed concrete. Biography Freyssinet was born in at Objat, Corrèze, France. He worked in the ''École Nationale des Ponts et Chaussées'' in Paris, France where he designed several bridges until the First World War intervened. His tutors included Charles Rabut. He served in the French Army from 1904 to 1907 and again from 1914 to 1918 as a road engineer. His most significant early bridge was the three span Pont le Veurdre near Vichy, built in 1911. At the time, the 72.5 metre (238 ft) spans were the longest so far constructed in France although Grafton Bridge a 97.6 metre reinforced concrete bridge had been opened in April 1910 and the Rocky River Bridge in Cleveland Ohio, an 85.34 metre unreinforced bridge had been opened in October 1910. Freyssinet's proposal was for three reinforced concrete truss spans, and was significantly less expensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when sub ...

Monument Historique
''Monument historique'' () is a designation given to some national heritage sites in France. It may also refer to the state procedure in France by which National Heritage protection is extended to a building, a specific part of a building, a collection of buildings, a garden, a bridge, or other structure, because of their importance to France's architectural and historical cultural heritage. Both public and privately owned structures may be listed in this way, as well as movable objects. As of 2012 there were 44,236 monuments listed. The term "classification" is reserved for designation performed by the French Ministry of Culture for a monument of national-level significance. Monuments of lesser significance may be "inscribed" by various regional entities. Buildings may be given the classification (or inscription) for either their exteriors or interiors. A monument's designation could be for a building's décor, its furniture, a single room, or even a staircase. An example is ...

Buildings And Structures In Moulins, Allier
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monuments Historiques Of Allier
A monument is a type of structure that was explicitly created to commemorate a person or event, or which has become relevant to a social group as a part of their remembrance of historic times or cultural heritage, due to its artistic, historical, political, technical or architectural importance. Some of the first monuments were dolmens or menhirs, megalithic constructions built for religious or funerary purposes. Examples of monuments include statues, (war) memorials, historical buildings, archaeological sites, and cultural assets. If there is a public interest in its preservation, a monument can for example be listed as a UNESCO World Heritage Site. Etymology It is believed that the origin of the word "monument" comes from the Greek ''mnemosynon'' and the Latin ''moneo'', ''monere'', which means 'to remind', 'to advise' or 'to warn', however, it is also believed that the word monument originates from an Albanian word 'mani men' which in Albanian language means 'rememb ...
