Chapter 14: Cable-stayed bridges

Following a brief history of cable-stayed bridges, this chapter describes the various materials and forms of construction that have been adopted for the major structural components of these bridges, focusing in turn on the cable system, the pylon and the deck. By the use of examples, the most appropriate use of these materials and component forms is discussed. A step-by-step approach is given for the preliminary design of the cable-stayed bridge, from outline proportions of the structure to static and dynamic analysis, including requirements for erection calculations and wind loading on stays. The dynamic behaviour for the cable-stayed bridge includes the phenomenon of stay oscillation, which is reviewed in detail, including discussion of the various types of dynamic cable response together with the available preventative measures.
