Yangluo Bridge
The Yangluo Yangtze River Bridge () is a suspension bridge over the Yangtze River in Wuhan, Hubei, China. With a main span of , at its opening it was tied with the Golden Gate Bridge as the ninth longest suspension bridge in the world. The bridge carries the G70 Fuzhou–Yinchuan Expressway and G4201 Wuhan Ring Expressway over the Yangtze River and provides easy access to both sides of the river as part of a larger plan to promote development in the eastern portion of the city. Construction on the bridge began on November 4, 2003, and it opened to traffic on December 26, 2007. History The Yangluo Bridge was the fourth bridge constructed over the Yangtze in Wuhan. The first was the Wuhan Yangtze River Bridge, known locally as the ''First Bridge'', built in 1957. This remained the only land link across the river for the next four decades and it became increasingly congested as the city grew. To alleviate the crowding on the bridge and promote further development in the city, Wu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Expwy G70 Sign No Name
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dynasti ...

Dorman Long
Dorman Long & Co was a UK steel producer, later diversifying into bridge building. It was once listed on the London Stock Exchange. History The company was founded by Arthur Dorman and Albert de Lande Long when they acquired ''West Marsh Iron Works'' in 1875. In the 1920s Dorman Long took over the concerns of Bell Brothers and Bolckow and Vaughan and diversified into the construction of bridges. In 1938 Ellis Hunter took over as Managing Director and he continued to lead the business until 1961. In 1967 Dorman Long was nationalised, along with 13 other British steel-making firms, becoming subsumed into the government-owned British Steel Corporation. In 1982 Redpath Dorman Long, the engineering part of the business, was acquired by Trafalgar House who in 1990 merged it into Cleveland Bridge & Engineering Company in Darlington. Iron and steel Iron-making has been known in Cleveland since the Romans found iron slags in North Yorkshire, with small-scale iron-making known ...

Ehuang Bridge
The Ehuang Yangtze River Bridge () crosses the Yangtze River in Hubei, China. The bridge carries traffic on China National Highway 106 between Echeng, Ezhou south of the river and Huangzhou, Huanggang to the north. Construction of the bridge started in 1999 and it was completed in 2002. The bridge is long and has a main span of placing it among the longest cable-stayed bridges in the world. See also * Yangtze River bridges and tunnels * List of largest cable-stayed bridges This list ranks the world's cable-stayed bridges by the length of main span, i.e. the distance between the suspension towers. The length of the main span is the most common way to rank cable-stayed bridges. If one bridge has a longer span than ano ...

Tianxingzhou Bridge
The Tianxingzhou Yangtze River Bridge () is a combined road and rail bridge across the Yangtze River in the city of Wuhan, the capital of the Hubei Province of China. The bridge crosses the Yangtze in the northeastern part of the city, a few kilometers downstream of the Second Wuhan Yangtze River Bridge. Its name is due to the Tianxing Island (天兴洲, Tianxingzhou), above which it crosses the river. Built at the cost of , the 4,657-meter cable suspension bridge was opened on December 26, 2009, in time for the opening of the Wuhan railway station. The bridges main span measures , the longest combined road and rail cable-stayed span in the world. Description The bridge is a combined road and rail bridge; it has 4 railroad tracks and 6 vehicular traffic lanes.China's new highway-railway b ...

Yangtze River Bridges And Tunnels
The bridges and tunnels across the Yangtze River carry rail and road traffic across China's longest and largest river and form a vital part of the country's transportation infrastructure. The river bisects China proper from west to east, and every major north–south bound highway and railway must cross the Yangtze. Large urban centers along the river such as Chongqing, Wuhan, and Nanjing also have urban mass transit rail lines crossing the Yangtze. Pontoon bridges have been used by militaries for two thousand years on the Yangtze, but until the completion of the Wuhan Yangtze River Bridge in 1957, there were no permanent bridges along the main stretch of the river known as ''Chang Jiang'' (the " Long River"), from Yibin to the river mouth in Shanghai, a distance of . Since then, over 75 bridges and six tunnels have been built over this stretch, the overwhelming majority since 1990. They reflect a broad array of bridge designs and, in many cases, represent significant achieve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Bridges In China
This list of bridges in China includes notable bridges. China has a long history in bridge construction. The oldest bridge still in existence in China is the Anji Bridge, constructed during the years between 595 and 605. During the infrastructure boom of the past two decades, bridge-building has proceeded at a rapid pace on a vast scale. Prior to the completion of the Wuhan Yangtze River Bridge in 1957, there were no bridges across the Yangtze River, China's longest, from Yibin to Shanghai, and all overland roads and railways crossing this 2,884 km (1,792 mi.) stretch of the river had to be ferried. There were only seven such bridges in 1992, but that number reached 73 by the end of 2012, including eight new openings in that year alone. China has been pushing the boundaries of bridge construction with many record breaking bridges, including: * The Danyang–Kunshan Grand Bridge, the world's longest bridge measuring over . * The Yangsigang Yangtze River Bridge in W ...

X-bracing
X-bracing is a structural engineering practice where the lateral load on a building is reduced by transferring the load into the exterior columns. X-bracing was used in the construction of the 1908 Singer Building, then the tallest building in the world. Some skyscrapers by engineer Fazlur Khan, such as the 1969 John Hancock Center The John Hancock Center is a 100- story, 1,128-foot supertall skyscraper located in Chicago, Illinois. Located in the Magnificent Mile district, the building was officially renamed 875 North Michigan Avenue in 2018. The skyscraper was designed ..., have a distinctive X-bracing exterior, allowing for both higher performance from tall structures and the ability to open up the inside floorplan (and usable floor space) if the architect desires.Ali Mir (2001), ''Art of the Skyscraper: the Genius of Fazlur Khan'', Rizzoli International Publications, References Structural engineering {{Engineering-stub ...

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 ...
