Abstract

Wind-induced vibration of stay cables such as the rain vibration has been studied. Typical countermeasures for that is the installation of dampers or cable-surface treatment. On the other hand, dry-state galloping of stay cables is recently more concerned, and its mechanism and design criteria are now vigorously studied. It is pointed out that there is a common mechanism in them of weakening Karman-vortex shedding by the axial flow behind a cable and critical Reynolds number effect. In this study, wind-induced response and surface pressure of an indented surface cable as well as a normal surface cable were experimentally investigated in order to study the characteristics and mechanisms for dry-state galloping.
