Mangfall Bridge
The Mangfall Bridge is a motorway bridge across the valley of the Mangfall north of Weyarn in Upper Bavaria, Germany, which carries Bundesautobahn 8 between Munich and Rosenheim. The original bridge, designed by German Bestelmeyer, opened in January 1936 as one of the first large bridges in the Reichsautobahn system and was influential in its design. Destroyed at the end of World War II, this bridge was replaced with a temporary structure in 1948; the current bridge consists of a replacement built in 1958–60 to a design by Gerd Lohmer and Ulrich Finsterwalder and a second span for traffic in one direction which was added in the late 1970s when the autobahn was widened to six lanes. Original bridge The original bridge was one of the first large bridges constructed for the Reichsautobahn system under the Third Reich, and was the model for many that followed. It was a steel beam bridge long, wide and carried on two double pylons of reinforced concrete high.Rainer Stommer, "T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Hitler
Adolf Hitler (; 20 April 188930 April 1945) was an Austrian-born German politician who was dictator of Nazi Germany, Germany from 1933 until Death of Adolf Hitler, his death in 1945. Adolf Hitler's rise to power, He rose to power as the leader of the Nazi Party, becoming the Chancellor of Germany, chancellor in 1933 and then taking the title of in 1934. During his dictatorship, he initiated European theatre of World War II, World War II in Europe by invasion of Poland, invading Poland on 1 September 1939. He was closely involved in military operations throughout the war and was central to the perpetration of the Holocaust: the genocide of Holocaust victims, about six million Jews and millions of other victims. Hitler was born in Braunau am Inn in Austria-Hungary and was raised near Linz. He lived in Vienna later in the first decade of the 1900s and moved to Germany in 1913. He was decorated during his Military career of Adolf Hitler, service in the German Army in Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (Compression (physics), 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 Tension (physics), 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 Wire rope, 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 fo ...

Dyckerhoff & Widmann (Dywidag)
Dyckerhoff & Widmann AG (Dywidag) was a construction company based in Munich, Germany (formerly based in Karlsruhe, Wiesbaden and Berlin, Germany). History The company was founded under the name ''Lang & Co.'' in 1865 by the German cement pioneer Wilhelm Gustav Dyckerhoff (1805–1894) in Karlsruhe, Germany. In the early years the company was mainly engaged in the production of concrete components. In 1866 Dyckerhoff's son Eugen Dyckerhoff (1844–1924) entered the company. He and his father-in-law Gottlieb Widmann changed the company's name to ''Dyckerhoff & Widmann'' and made it one of the leading companies for concrete construction in Germany. Starting in the field of construction engineering in the 1880s, the company soon got contracts for impressive buildings like the Centennial Hall (''Jahrhunderthalle'') in Wroclaw. The company introduced many innovations in the field of concrete construction. Eugen Dyckerhoff developed the ''Stampfbeton'', a compressed concrete that bec ...

Reichsbahn
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorganise ... [...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. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct 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 strength to maintain its own shape, and ...

Hitler Youth
The Hitler Youth (german: Hitlerjugend , often abbreviated as HJ, ) was the youth organisation of the Nazi Party in Germany. Its origins date back to 1922 and it received the name ("Hitler Youth, League of German Worker Youth") in July 1926. From 1936 until 1945, it was the sole official boys' youth organisation in Germany and it was partially a paramilitary organisation. It was composed of the Hitler Youth proper for male youths aged 14 to 18, and the German Youngsters in the Hitler Youth ( or "DJ", also "DJV") for younger boys aged 10 to 14. With the surrender of Nazi Germany in 1945, the organisation ''de facto'' ceased to exist. On 10 October 1945, the Hitler Youth and its subordinate units were outlawed by the Allied Control Council along with other Nazi Party organisations. Under Section 86 of the Criminal Code of the Federal Republic of Germany, the Hitler Youth is an "unconstitutional organisation" and the distribution or public use of its symbols, except for educa ...

Wehrmacht
The ''Wehrmacht'' (, ) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the ''Heer'' (army), the ''Kriegsmarine'' (navy) and the ''Luftwaffe'' (air force). The designation "''Wehrmacht''" replaced the previously used term and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted. After the Nazi rise to power in 1933, one of Adolf Hitler's most overt and audacious moves was to establish the ''Wehrmacht'', a modern offensively-capable armed force, fulfilling the Nazi régime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbours. This required the reinstatement of conscription and massive investment and defense spending on the arms industry. The ''Wehrmacht'' formed the heart of Germany's politico-military power. In the early part of the Second World War, the ''Wehrmacht'' employed combined arms tactics (close- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gustavsburg
The double city of Ginsheim-Gustavsburg in the northwest of the Groß-Gerau district in the German state of Hesse, has about 16,000 inhabitants. It is part of what is called the Rhine-Main region in Germany which has the city of Frankfurt am Main at its centre. Geography Location Ginsheim-Gustavsburg lies south of the Main and north of the Rhine in the so-called ''Mainspitze'' triangle, a narrow piece of land between the Main and Rhine where the former empties into the latter.

MAN SE
MAN SE (abbreviation of ''Maschinenfabrik Augsburg- Nürnberg'', ) was a manufacturing and engineering company based in Munich, Germany. Its primary output was commercial vehicles and diesel engines through its MAN Truck & Bus and MAN Latin America divisions, and participation in the manufacturer Sinotruk. MAN SE was majority-owned by Traton, the heavy commercial vehicle subsidiary of automaker Volkswagen AG, until August 2021 when Traton completed a squeeze out of all remaining shareholders and formally merged MAN SE into Traton SE, meaning the former subsidiaries of MAN SE were now directly owned by Traton, and MAN SE ceased to exist. History Foundation MAN traces its origins back to 1758, when the "St. Antony" ironworks commenced operation in Oberhausen, as the first heavy-industry enterprise in the Ruhr region. In 1808, the three ironworks "St. Antony", "Gute Hoffnung" (English: "Good Hope"), and "Neue Essen" (English: "New Forges") merged, to form the Hüttengewer ...
