BNG CONSULTANTS / BNG VINA BNG BRIDGE Cable-Stayed Bridge Cable-Stayed Bridge A cable-stayed bridge is a bridge that consists of one or more columns (normally referred to as towers or pylons), with cables supporting the bridge deck. Cable-stayed bridges may look similar to suspensions bridges-both have roadways that hang from cables and both have towers. But the two bridges support the load of the roadway in very different ways. The difference lies in how the cables are connected to the towers. In suspension bridges, the cables ride freely across the towers, transmitting the load to the anchorages at either end. In cable-stayed bridge, the towers form the primary load-bearing structure. A cantilever approach is often used for support of the bridge deck near the towers, but areas further from them are supported by cables running directly to the towers. This has the disadvantage, compared to the suspension bridge, that the cables pull to the sides as opposed to directly up, requiring the bridge deck to be stronger to resist the resulting horizontal compression loads; but has the advantage of not requiring firm anchorages to resist a horizontal pull as in the suspension bridge. All static horizontal forces are balanced so that the supporting tower does not tend to tilt or slide, needing only to resist such forces from the live loads. The steel-decked bridge designed at Stromsund by Franz Dischinger(1956) is therefore more often cited as the first modern cable-stayed bridge. The Tatara Bridge is a cable stayed bridge with a total length of 1480m and a center span of 890m which is the longest center span in the world. But The Sutong Changjiang Highway Bridge over the Yangtze River is seen under construction in east China s Jiangsu Province, April 23,2007. The cable-stayed bridge will have a world record 1088m main span and tallest cable towers when completed in 2008.

BNG CONSULTANTS / BNG VINA BNG BRIDGE Extradosed Bridge Extradosed Bridge This type of bridge was first proposed by Jacques Mathivat in 1988. The tendons are arranged outside the girders, which are inside conventional girder bridges. It results in the prestressing forces with greater eccentricity acting more effectively on the main girder. The external appearance resembles cable-stayed bridges, but the structural characteristics are comparable to those of girder bridges. The distinctive features of extradosed bridges are as the followings. Applying external prestressing, the girder height can be set shorter than that of standard girder bridges. The cables (prestressing tendons outside the girders) need no tension adjustment necessary for cable-stayed bridges, and can be treated as usual tendons in the girder bridge. The height of pylons can be as half as those of cable-stayed bridges, therefore easier construction can be executed. With small stress fluctuation under live load, the anchorage method for the stayed cables can be the same as that of tendon inside the girder, then the excess cost can be cut. It is the best choice that application of this type bridge to a bridge with main span of 110~200m.
