A study on wake-galloping for stay cables of extradosed bridges employing full aeroelastic cable model
Abstract
The aerodynamic stability of the twin cables of extradosed bridges was investigated through a series of wind tunnel tests employing full aeroelastic cable model. The cable arrangement employed here is characterized by that W/D varies from 4.3 to 8.7 (where W is spacing of centers of cables, D is diameter of the cable), namely corresponds to the value between the critical condition of ‘wake-galloping’ and so called ‘wake-induced flutter’. Consequently, the most effective damping device was installed considering the result of the wind tunnel test investigating the effect of W/D, the incidence angle, natural frequency, structural damping.
