Structural performance of cable-stayed bridges

For centuries man has seen the need to create mechanisms to improve their quality of life, one of these innovations is the construction of bridges, which throughout history has undergone many changes in its structure to become what now known as cable-stayed bridges.

The history of cable-stayed bridges began in the nineteenth century when the first bridges arise from this type of steel as is the bridge Driburgh Abbey in Scotland, presented by failures in building collapse, so the engineers of the time dismissed the idea of this type of construction, however, despite the rejections, after World War II collapsed bridges are rebuilt, using new techniques and discovered that the cable-stayed bridge type require less material and therefore are much cheaper.

Regarding the definition of cable-stayed bridges can say that manifest as a variation of suspension bridges, cable-stayed a solution being preferred because they exhibit different characteristics that make them more robust and economical, (for the quantity of material which are constructed cone) since most are steel and prestressed concrete.

Moreover, the structural behavior of cable-stayed bridges is given by the joint work of all its features which consequently produce greater stability and strength capable of withstanding loads more effectively exerted on these and also environmental effects those who are constantly exposed.

Continuing with the above, cable-stayed bridges are formed by three fundamental as are the straps, rigid structure which provides the bridging strength and stability are also the towers, which allow establishing the straps to and generate the necessary hardware, for Finally we have the board, which completes the process of stability and balances the force exerted by the straps so that the bridge holds equal weight on all surfaces.

In relation to the braces and the tower, these represent not only a factor in the behavior of the bridge, also have variations which generate various types of cable bridges which can be found in bridges with suspenders Harps multiple bridges in Fan, with triple braces and bridges Wye double straps, all with modern and innovative structural designs.

Finally, note that they are everyday innovations emerging in the field Jan constructive special item of bridges, which generate multiple options when building and today all suggest that stayed bridges are a great solution engineering development of transport routes and gradually spread throughout the world with new concepts according to the needs of each place.
