What is the difference between Extradosed and cable-stayed bridge?
On cable-stayed bridges, the stays commonly support at least 80% of the loading from vehicular traffic acting on the bridge superstructure, whereas on extradosed bridges, the stay cables typically support only between 20% and 60% of this load.
What is a Extradosed bridge used for?
Thus, the primary role of cables in an extradosed concrete bridge is to provide pre-compression to control the stresses within the concrete section.
Where is the longest cable-stayed bridge in the world?
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.
What is 1 advantage to a cable-stayed bridge?
The following are key advantages of the cable-stayed form: much greater stiffness than the suspension bridge, so that deformations of the deck under live loads are reduced. can be constructed by cantilevering out from the tower – the cables act both as temporary and permanent supports to the bridge deck.
What are the advantages and disadvantages of a cable-stayed bridge?
Although a cable-stayed bridge can help to provide a consistently supportive deck when there are crosswinds present over a span, this option does not work well when the speed of that wind remains consistently high. This disadvantage occurs because of the rigidity that the cables provide for the overall structure.
How many cable-stayed bridge in India?
There are number of Cable-Stayed Bridges in India and 5 Cable-Stayed Bridges Under Construction.
Which is the 57th longest cable-stayed bridge in the world?
The Russky Bridge over the Eastern Bosphorus in Vladivostok, Russia, with its 1,104 metres (3,622 ft) span, has the longest span of any cable-stayed bridge, displacing the former record holder, the Sutong Bridge over the Yangtze River in the People’s Republic of China 1,088 metres (3,570 ft) on 12 April 2012.
What is the maximum length of a cable-stayed bridge?
In general, a cable-stayed bridge is less efficient in carrying dead load than a suspension bridge but is more efficient in carrying live load. The most economical span length for a cable stayed bridge is 100–350 m, though some designers have extended this range to as much as 800 m.
What are disadvantages of a cable-stayed bridge?
List of the Cons of a Cable Stayed Bridge
- It can be an unstable design in certain environments.
- It has a maximum length.
- It can be a bridge design that is difficult to inspect.
- It can be susceptible to corrosion.
- It is only advantageous for short or medium distance needs.
How many cables hold up the Golden Gate Bridge?
two main
The Golden Gate Bridge has two main cables which pass over the tops of the two 746-ft-tall towers and are secured at either end in giant anchorages.
How much weight can a cable-stayed bridge hold?
The load on each tower from main cables is 61,500 tons (56,000,000 kg). The weight of both main towers is 44,000 tons (40,200,000 kg). Transverse deflection of towers is 12.5 in (0.32 m).
