Cable Stayed Bridge Or Suspension Bridge

Cable-stayed suspension hybrid bridge has become a popular type of bridges throughout the world because of its aesthetic shape structural efficiency and economical construction. As the modern day demands put forward greater challenges for the construction of longer spans or taller.

Compare this with the suspension bridges that have to be no less than 2000 meters long for a start.

Cable stayed bridge or suspension bridge

. Cable-stayed bridge bridge form in which the weight of the deck is supported by a number of nearly straight diagonal cables in tension running directly to one or more vertical towers. The best known of these hybrid structures is the Brooklyn Bridge New York 1883 with a 486-meter main span. The principles of cables and towers are at each end with strong.

The principal difference between the suspension bridge and the cable stated bridge is the fact that suspension bridge was constructed by the ancient communities using rope and bamboo. 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. There are two major classes of cable- stayed bridges.

ADVANTAGES OF CABLE STAYED BRIDGE. Cable stay bridges can support a curving bridge but suspension bridges reqire a straight bridge. Post Tension Specialist The first example of Cable Stayed Bridge merges the features of both suspension bridge and cable stayed bridge like Brooklyn Bridge.

The difference in the design is that the cables hold the deck by connecting it directly to the support pillars instead of using suspending wires or cables to stabilize the span. At specific points along the main cable each being the exact distance horizontally in relation to the next devices called cable bands are installed to carry steel wire ropes called Suspender cables. Cable bridges such as cable-stayed bridges and suspension bridges are supported by members such as cables reinforced girders and pylons.

A cable-stayed bridge one of the most modern bridges consists of a continuous strong beam girder with one or more pillars or towers inside the middle. A cable-stayed bridge offers a design that is similar to a suspended bridge It will have towers that help to support the structure while the deck is held in place by cables. Cables stretch diagonally between these pillars or towers and the beam.

Predecessors for modern cable-stayed bridges appeared in the 19 th century in the form of different hybrid combinations of suspension systems with additional diagonal straight cables as in the case of the Albert Bridge UK 1873. Cable-stayed bridge has better structural stiffness and suspension bridge has ability to offer longer span. Perhaps the most significant downside of this bridge is that it has a short maximum length of around 1000 meters.

Cable-stayed bridges are a popular choice as they offer all the advantages of a suspension bridge but at a lesser cost for spans of 500 to 2800 feet 152 to 853 meters. Start studying Cable Stayed BridgeSuspension Bridge. Both of these two have wide range of scale and functions from pedestrian traffic to highways.

The cables are anchored in the tower rather than at the end. Suspension bridges are usually structurally more optimized and have less redundancy and ductility with lighter decks and higher level of engineering technology. The most economical span length for a cable stayed bridge is 100350 m though some designers have extended this range to as much as 800 m.

Fires on the bridge can cause structural degradation in members which can pose a severe danger to the bridge. Combination of above two structural systems could achieve a very. The wire used in suspension bridge construction is a galvanized steel wire that has been coated with corrosion inhibitors.

They require less steel cable are faster to build and incorporate more precast concrete sections. Cons of Cable-Stayed Bridges. In short cable-stayed bridges bear the road-deck weight differently are faster to build and require less construction materials than suspension bridges.

Learn vocabulary terms and more with flashcards games and other study tools. The towers transfer the cable forces to the foundations through vertical compression. 9 Cable-Stayed Bridges Cable-stayed bridges may appear to be similar to suspension bridges but in fact they are quite different in principle and in their construction.

This curtails the range of applicability of this kind of bridge for daily use. Fan type which are the most efficient and Harp or parallel type which allow more space for the fixings.
