Angers Bridge
Angers Bridge, also called the Basse-Chaîne Bridge, was a suspension bridge over the Maine (river), Maine River in Angers, France. It was designed by Joseph Chaley and Bordillon, and built between 1836 and 1839.Peters, Tom F., ''"Transitions in Engineering: Guillaume Henri Dufour and the Early 19th Century Cable Suspension Bridges"'', Birkhauser, 1987, The bridge collapsed on 16 April 1850, while a battalion of French soldiers was marching across it, killing over 200 of them. The bridge spanned , with two wire cables carrying a deck wide. Its towers consisted of cast iron columns tall. Collapse Soldiers stationed in the region frequently used the bridge, and two battalions of the same regiment had crossed earlier that day. The third battalion arrived during a powerful thunderstorm when the wind was making the bridge oscillate. When the soldiers began to cross, their bodies acted as sails, further catching the wind.

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] |
Bridges Completed In 1839
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way 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, and 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 still in existence and use.

1850 Disasters In Europe
Year 185 ( CLXXXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Lascivius and Atilius (or, less frequently, year 938 ''Ab urbe condita''). The denomination 185 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Buildings And Structures In Angers
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 artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jacob Pieter Den Hartog
Jacob Pieter Den Hartog (July 23, 1901 Ambarawa, Dutch East Indies – March 17, 1989) was a Dutch–American mechanical engineer and Professor of Mechanical Engineering at MIT. Biography J. P. Den Hartog was born in 1901 in Ambarova, the Dutch East Indies. In 1916 his family moved to Holland. After attending high school in Amsterdam, he enrolled at Delft University of Technology in 1919 and received his MSc degree in electrical engineering in 1924. Unable to find suitable work in the Netherlands, he emigrated to the United States in 1924. From 1924 to 1930 he worked as an electrical engineer in the research laboratory of Westinghouse Electric (1886) in Pittsburgh. There under the influence of Stephen P. Timoshenko, who took him as his assistant, he began to study electrical and mechanical vibrations. At the same time, he attended night classes in Mathematics at the University of Pittsburgh, where he became an authority in problems on mechanics and vibration and received a do ...

Millennium Bridge (London)
The Millennium Bridge, officially known as the London Millennium Footbridge, is a steel suspension bridge for pedestrians crossing the River Thames in London, England, linking Bankside with the City of London. It is owned and maintained by Bridge House Estates, a charitable trust overseen by the City of London Corporation. Construction began in 1998, and it initially opened on 10 June 2000. Londoners nicknamed it the "Wobbly Bridge" after pedestrians experienced an alarming swaying motion on its opening day. The bridge was closed later that day and, after two days of limited access, it was closed again for almost two years so that modifications and repairs could be made to keep the bridge stable and stop the swaying motion. It reopened in February 2002. The bridge is located between Southwark Bridge and Blackfriars Railway Bridge. Its southern end is near the Globe Theatre, the Bankside Gallery, and Tate Modern, while its northern end is next to the City of London School below S ...

Tacoma Narrows Bridge (1940)
The 1940 Tacoma Narrows Bridge, the first Tacoma Narrows Bridge, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. The bridge's collapse has been described as "spectacular" and in subsequent decades "has attracted the attention of engineers, physicists, and mathematicians". Throughout its short existence, it was the world's third-longest suspension bridge by main span, behind the Golden Gate Bridge and the George Washington Bridge. Construction began in September 1938. From the time the deck was built, it began to move vertically in windy conditions, so construction workers nicknamed the bridge Galloping Gertie. The motion continued after the bridge opened to the public, despite several damping measures. The bridge's main span finally collapsed in winds on th ...

Broughton Suspension Bridge
Broughton Suspension Bridge was an iron chain suspension bridge built in 1826 to span the River Irwell between Broughton and Pendleton, now in Salford, Greater Manchester, England. One of Europe's first suspension bridges, it has been attributed to Samuel Brown, though some suggest it was built by Thomas Cheek Hewes, a Manchester millwright and textile machinery manufacturer. On 12 April 1831, the bridge collapsed, reportedly due to mechanical resonance induced by troops marching in step. As a result of the incident, the British Army issued an order that troops should "break step" when crossing a bridge. Though rebuilt and strengthened, the bridge was subsequently propped with temporary piles whenever crowds were expected. In 1924 it was replaced by a Pratt truss footbridge, still in use. Construction In 1826, John Fitzgerald, the wealthy owner of Castle Irwell House (later to become the site of the Manchester Racecourse), built, at his own expense, a suspension brid ...
