List Of Tallest Freestanding Steel Structures
This is a list of tallest freestanding steel structures in the world past and present. To be a freestanding steel structure it must not be supported by guy wires, the list therefore does not include guyed masts and the main vertical and lateral structural elements and floor systems in the case of buildings, are constructed from steel. This type of construction is a rarity today as most tall buildings are built with a composite structure featuring a reinforced concrete core. Oil platforms built using rigid steel jackets, such as the Bullwinkle (oil platform), are included and ranked as the local medium(water) does not provide any horizontal support. In fact they are over engineered specifically to resist water forces them rather than modulate them as compliant towers are designed to do. Demolished structures and structures under construction are also included but not ranked. Steel Structures (above 275 m / 900 ft in height) indicates a structures no longer standing. indicates ...

Guyed Mast
A guyed mast is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground or a base) for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported or bear loads. It requires guy lines to stay upright and to resist lateral (shear) forces such as wind loads. Examples include masts on sailing vessels, towers for telecommunications, meteorology, and masts on cranes, power shovels, draglines, and derricks, starting with the simple gin pole. Applications The principal applications of guyed masts are the masts of sailing vessels, guyed towers, and as the main tower of heavy equipment such as cranes, power shovels, draglines, and derricks, the simplest of which is the gin pole. Guyed masts are frequently used for radio masts and towers. The mast can either support radio antennas (for VHF, UHF and other microwave bands) mounted at its top, or th ...

Electricity Pylon
A transmission tower (also electricity pylon, hydro tower, or pylon) is a tall structure, usually a lattice tower made of steel that is used to support an overhead power line. In electrical grids, transmission towers carry high voltage, high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations, from which electricity is delivered to end consumers; moreover, utility poles are used to support low voltage, lower-voltage electric power transmission, sub-transmission and distribution lines that transport electricity from substation, substations to electricity customers. There are four categories of transmission towers: (i) the suspension tower, (ii) the Dead-end tower#Termination pylon, dead-end terminal tower, (iii) the Dead-end tower, tension tower, and (iv) the transposition tower. The heights of transmission towers typically range from , although when longer spans are needed, such as for crossing water, taller towers are s ...

Jiangyin
Jiangyin (, Jiangyin dialect: ) is a county-level city on the southern bank of the Yangtze River. It is administered by the Wuxi, Jiangsu province. Jiangyin is an important transport hub on the Yangtze River and one of the most developed counties in China. It had 1,595,138 inhabitants in the 2010 census. The city is part of the Jiangyin-Zhangjiagang-Jingjiang metropolitan area, which has 3,526,260 inhabitants.

History Jiangyin was initially a township of Yanling (; later known as Piling, ) county. Since the township was located north of Ji Lake, it was given the name "Jiyang" (). In 281, it was promoted to a county of the Piling commandery. In 558, the northwestern part was separated from Lanling county ( Wujin and its surrounding areas) to create Jiangyin county. It served as the seat of the Jiangyin commandery, with the same jurisdiction of the modern city, unt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yangtze River Crossing
The Yangtze River power line crossings are overhead power lines that cross the Yangtze River in China. There are at least three power line crossings on the Yangtze River at Jiangyin, Nanjing, and Wuhu. The towers of the crossing in Jiangyin are among the highest in the world. Jiangyin One exists at Jiangyin, Jiangsu Province, China. Each pylon is situated at and at . It is a section of the 500 kV power line from the Yancheng power station to the Dou Shan substation in the province of Jiangsu. The power line section running over the river has a span width of . It is carried by two tall suspension towers, each weighing 4,192 tonnes. (for comparison, the towers even surpass the height of the Eiffel Tower, which is , including antenna). They are identical lattice towers of square cross section with an area of × 68 m at the base and × 8 m at the top.

Kyiv TV Tower
The Kyiv TV Tower () is a lattice tower, lattice metal tower on Oranzhereina Street, Kyiv, Ukraine, and is the tallest structure in the country. The tower was built in 1973 while Kyiv was the capital of Ukrainian SSR. The tower was the tallest freestanding metal structure in the world. It is used for radio and television broadcasting and is not open to the public. It is the tallest lattice tower in the world and third tallest structure in Europe. History The tower was first designed for Moscow, then the Soviet capital. But Moscow authorities preferred a more "solid" type of tower, which was eventually built (Ostankino Tower). Later, when Kyiv needed its own tower, the project was reintroduced. The Soviet government ordered the engineers to shorten the tower by almost 30%, so as not to be as tall as the Moscow one. Location The tower was built on top of the Jewish cemetery in Lukyanivka (neighborhood), Lukianivka. The cemetery was officially closed in 1966 and Jewish famili ...

Cognac Platform
Cognac ( , also , ) is a variety of brandy named after the commune of Cognac, France. It is produced in the surrounding wine-growing region in the departments of Charente and Charente-Maritime. Cognac production falls under French appellation d'origine contrôlée (AOC) designation, with production methods and naming required to meet certain legal requirements. Among the specified grapes, Ugni blanc, known locally as Saint-Émilion, is most widely used. The brandy must be twice distilled in copper pot stills and aged at least two years in French oak barrels from Limousin or Tronçais. Cognac matures in the same way as whiskies and wines barrel-age, and most cognacs spend considerably longer "on the wood" than the minimum legal requirement. Production process Cognac is a type of brandy, and after the distillation and during the aging process, is also called ''eau de vie''. It is produced by twice distilling wine made from grapes grown in any of the designated growing regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
