Abstract

This study aims to clarify the generation mechanisms of dry state galloping instability of inclined Stay-Cables. Recently, a violent cable vibration under strong wind was observed in a cable-stayed bridge in Japan. The factors of that vibration might be the axial flow effect, which is formed in the wake of inclined cable. Two different results are reported. One reports that structural damping is very useful for controlling the aerodynamic vibration, and the other reports that structural damping is not so useful. In this study, focusing on the axial flow considered as the same effect in the point of repression of Karman vortex shedding, wind tunnel tests are carried out in order to clarify the effect of the Scruton number.
