high-speed vortex induced vibration and galloping instability of inclined cable

Abstract

This paper describes wind-induced vibration of inclined cables of cable-stayed bridges.This vibration may not be expressed by only galloping type vibration but also the vortex-related phenomena. To clarify this phenomenon, wind tunnel tests are carried out from the view point of applying the quasi-steady theory to inclined cable aerodynamics and span-wise upper water rivulet locations related to the characteristics of Karman vortex shedding.
