Abstract
Wind-induced cable vibrations can be classified into several types such as buffeting due to wind gust, vortex-induced vibration, classical galloping with iced cables, wake galloping, parametric excitation, Reynolds number related drag instability, rain–wind induced vibration, high-speed vortex excitation and dry galloping. Among these vibration types, vortex induced vibration and buffeting due to wind gust are generally small amplitude while the last three types are mainly related to stay cables with larger amplitude vibration and the rain–wind induced vibration is the one most frequently observed on site of bridge. Furthermore, mechanism of rain–wind vibration has been fully elucidated in recent years, and some effective control methods have been successfully applied in practice. In particular, dry galloping is still less understood and it would require research that is more intensive. Hence, the aim of this paper is to elucidate the cable vibration characteristic in no rain condition (called “Dry galloping”) by wind tunnel test. Finally, the detail of its generation mechanism will be investigated and discussed.
