Analysis of stay-cable vibrations at the Franjo Tudman Bridge in Dubrovnik

Stay cable vibrations occurring on existing cable stayed bridges are most often due to simultaneous rain and wind action. Although stay cable vibrations can be estimated by comparison to cable stayed-bridges under similar conditions and by analytical procedures, most accurate estimates con be obtained by wind tunnel testing. Stay cubic vibrations can be prevented by aerodynamic, structural and mechanical measures. The theoretical base and the analysis of stay cable vibrations on the Franjo Tudman Bridge in Dubrovnik are presented in the paper.
