ResumoThis paper aims to provide evidence of the rapid progress in cable-stayed bridges. The span record progressed rapidly during the last 10 years, passing from 465 to almost 900 m; it is now expected that 1200 m will be reached soon, if care is taken with regard to aerodynamic stability and dynamic response to turbulent wind, which can be now mastered. Cable vibrations, which have been extensively analysed in the last few years, can also be controlled by different types of countermeasures. However, cable-stayed bridges have also developed in directions other than very long spans: flexible decks, extradossed cables and multispan cable-stayed bridges which will certainly receive a wider development for large projects.
