Cable-stayed bridge is a bridge similar to suspended bridge in that it has towers and a deck that is held by cables, but its cables hold the deck by connecting it directly to the towers instead via suspender cables. It usually carries pedestrians, bicycles, automobiles, trucks, and light rail.
How do cable-stayed bridge work?
In suspension bridges, the cables ride freely across the towers, transmitting the load to the anchorages at either end. In cable-stayed bridges, the cables are attached to the towers, which alone bear the load. … In a radial pattern, cables extend from several points on the road to a single point at the top of the tower.
How many cable-stayed bridge in India?
A cable-stayed bridge has one or more towers to support the bridge deck using the cables, Basically Cable-Stayed Bridges are longer than cantilever bridges and shorter than suspension bridges. There are number of Cable-Stayed Bridges in India and 5 Cable-Stayed Bridges Under Construction.
What makes a cable-stayed bridge strong?
In the cable-stayed bridge, the cables deliver all of the weight of the bridge to the towers, and therefore, the bridge doesn’t need to be anchored to the shores. The cable-stayed design uses less steel cable than a suspension bridge, and is faster and easier to build.
What is cable bridge in electrical?
A cable raceway or cable bridge is an enclosed conduit that forms a physical pathway for electrical wiring. Cable Raceways protect wires and cables from heat, humidity, corrosion, water intrusion and general physical threats.
What is the world’s longest cable-stayed bridge?
The Sutong Bridge 1. The Sutong Bridge arcs across a 6-kilometer-wide stretch of the mighty Yangtze River 50 miles upstream from Shanghai. Measuring 8.2 km overall, its main span is the current world record-holder for a cable-stayed bridge.
Where are cable-stayed bridges located?
1.3. 8.5 Cable-Stayed Bridges
|3||Stonecutters Bridge||Tsing Yi-Stonecutters Island|
What is a disadvantage of a cable-stayed bridge?
List of the Cons of a Cable Stayed Bridge. 1. It can be an unstable design in certain environments. A cable stayed bridge should not be installed in a region that is known to experience high wind speeds on a consistent basis.
What is a cable-stayed bridge for kids?
A cable-stayed bridge is a bridge that has one or more columns (called towers or pylons), with cables directly supporting the bridge deck. There are two main types of cable-stayed bridges. In the harp design, the cables are nearly parallel.
Which is longest cable-stayed bridge in India?
Prime Minister Narendra Modi inaugurated a 1.4-kilometer long four-lane bridge over the river Narmada in Bharuch, Gujarat. It is reportedly the longest ‘extradosed’ cable-stayed bridge in the country.
Which is largest cable-stayed bridge in India?
Vidyasagar Setu Vidyasagar Setu also known as the Second Hooghly Bridge, is a toll bridge over the Hooghly River in West Bengal, India, linking the twin cities of Kolkata (previously known as Calcutta) and Howrah.
Where is biggest cable bridge in India?
Bharuch India’s longest cable-bridge inaugurated in Gujarat. Prime Minister Narendra Modi on Tuesday inaugurated India’s longest cable-bridge in Bharuch, Gujarat, which is 1,344 metres long and 22.8 metres wide. The bridge, built by Larsen and Toubro on river Narmada, has 216 cables of 25-40 metres length.
What type of bridge is the strongest and why?
An arch bridge is stronger than a beam bridge, simply because the beam has a weak point in the center where there is no vertical support while arches press the weight outward toward the support.
What is the average span of a cable-stayed bridge?
110 to 480 meters The typical span length of cable stayed bridges range from 110 to 480 meters. The longest cable stayed bridge in the world is presently the Tatara Bridge with a main span of 890 m. The articulation of the structure allows for a shallow superstructure with open and uncluttered views from the bridge.
How do you build a cable-stayed bridge?
The basics of cable-stayed bridge design are as follows: the vertical loads on the deck are supported by diagonal cable stays that transfer these loads to the towers. At the tower, the horizontal components of the cables from the main span are in balance with those from the side/adjacent spans.
How strong is a cable bridge?
Conventional galvanized steel wire for bridge cable has a tensile strength of 1.6 GPa.
What is bridge cable made of?
Today, the cables are made of thousands of individual steel wires bound tightly together. Steel, which is very strong under tension, is an ideal material for cables; a single steel wire, only 0.1 inch thick, can support over half a ton without breaking.
What is suspension cable?
[sspenshn kbl] (engineering) A freely hanging cable; may carry mainly its own weight or a uniformly distributed load.
Where is longest cable-stayed bridge in us?
With a main cable-stayed span stretching 1,583 feet, John James Audubon Bridge is the longest cable-stayed bridge in the United States. Completed in 2011, the bridge crosses the Mighty Mississippi, carrying Louisiana Highway 10 between the Pointe Coupee and West Feliciana parishes (north of Baton Rouge).
What forces act on a cable-stayed bridge?
A cable-stayed bridge, with forces of tension represented by red lines and forces of compression by green lines. Encyclopdia Britannica, Inc. Construction of cable-stayed bridges usually follows the cantilever method, so their construction begins with the sinking of caissons and the erection of towers and anchorages.
Is the Golden Gate Bridge a cable-stayed bridge?
Longest suspension bridge in the world The Golden Gate Bridge is a suspension bridge, meaning it relies on cables and suspenders under tension along with towers under compression to cross a long distance without any intermediate supports.
Who built long cable stayed bridge?
More than 32.2km of cables built from 200,000t of steel were used for the bridge construction. China Harbour Engineering Company and Second Navigation Engineering Bureau (SNEB) were the main contractors for the project.
When were cable stayed bridges invented?
Two German designers, Dischinger and F. Leonhardt, working independently, built the first cable stayed bridges at Stromsund, Sweden (1955) with a 183 metre span and Dusseldorf, Germany (1957) with a 260 metre span. This type of bridge is seen as aesthetically attractive, economic and easier to construct.
Do cable-stayed bridges sway?
A cable-stayed bridge is a bridge design which uses large steel cables suspended from high towers or pylons to support the bridge decking. The cable-stayed bridge design is typically used on bridges that span great distances. … The result is a cable-stayed bridge that does not sway in the wind.
Why would a designer choose a cable-stayed bridge over a suspension bridge?
The symmetrical building of the road deck balances the load, eliminating the need for large ground anchorages. … In short, cable-stayed bridges bear the road-deck weight differently, are faster to build and require less construction materials than suspension bridges.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
