Description

Somewhat similar to suspension bridges like Golden Gate Bridge and Brooklyn Bridge, cable-stayed bridges like Terenez Bridge use steel cables to transfer loads from the bridge deck to the towers. However, cable-stayed bridges actually are very different from suspension bridges in principles and method of construction. In a suspension bridge, the long cables are the primary load-bearing structures that are mainly responsible for the function of the bridge; for a cable-stayed bridge, the pylons form the primary load-bearing structures. For a bridge span of medium length, like that of Terenez Bridge, a cable-stayed design is optimal from both structural and economic perspectives. Since the cables of Terenez Bridge will not be exerting large horizontal tensile forces on the anchorages, construction of the bridge does not require excellent soil conditions. The deck of a cable-stayed bridge will also be stiffer than that of a suspension bridge, and therefore deformations of the deck under live loads are generally smaller. In addition, construction of a cable-stayed bridge will be simpler since the structure can be built by cantilevering out from the pylons.
