Cable-stayed bridge configurations have become more common over the past several decades for bridges in the medium- to long-span range. Nonetheless, in some cases, serviceability problems involving large-amplitude vibrations of stay cables under certain wind and wind–rain conditions have been observed. This study was conducted in response to State transportation department interest in developing improved design guidance for mitigation of excessive cable vibrations on cable-stayed bridges. The study included full-scale forced vibration tests on the cables of a new cable-stayed bridge to characterize the dynamic behavior of cables and evaluate the effectiveness of mitigation details such as crossties. The results of this study will be made available to the Post-Tensioning Institute's DC-45 Cable-Stayed Bridge Committee for consideration during periodic updates of their Recommendations for Stay Cable Design, Testing and Installation publication.
This report will be of interest to bridge engineers, wind engineers, and consultants involved in the design of cable-stayed bridges. It is the sixth in a series of reports addressing the subject of aerodynamic stability of bridge stay cables.

| 16. Abstract
Cable-stayed bridges have been recognized as the most efficient and cost effective structural form for medium- to long-span bridges over the past several decades. With their widespread use, cases of serviceability problems associated with large-amplitude vibration of stay cables have been reported. Stay cables are laterally flexible structural members with low inherent damping and thus are highly susceptible to environmental conditions such as wind and rain–wind combinations. |
