Abstract

Dry inclined cable galloping has recently been identified as a potential mechanism for large amplitude vibrations of inclined cables on long-span cable-stayed bridges. An approach to the analysis of this behaviour, using quasi-steady theory, has been put forward, which is a generalisation of galloping analysis, considering critical Reynolds number effects and the 3D geometry. In this paper, this approach is extended to allow for the effects of turbulence of the oncoming flow, which is shown to be very beneficial in reducing the level of structural damping required to prevent the galloping from occurring.
