Abstract

A cable-stayed bridge is a structural system with a continuous girder supported by inclined stay cables from the towers. Form the mechanical point of view, the cable-stayed bridge is a continuous girder bridge supported by elastic supports. The cable-stayed bridge ranks first for a span range approximately from 150 to 600 m, which has spanning capacity longer than that of cantilever bridges, truss bridges, arch bridges, and box girder bridges, but shorter than that of suspension bridges. In this range, the cable-stayed bridge is very economical and has elegant appearance due to the relatively small girder depth and has proved to be very competitive against other bridge types. In this chapter, the classification, configuration, and construction methods of cable-stayed bridges are discussed.
