Vortex-induced cable vibration of cable-stayed bridges at high reduced wind velocity
In this paper, mechanisms of vortex-induced vibration of inclined cables at high reduced wind velocity region are discussed using results from a series of wind tunnel tests. As a conclusion, this aerodynamic instability of inclined cables would occur by the fluid interaction between Karman vortex and axial vortex. Also, the axial flow along the cable axis and the upper water rivulet control this aerodynamic instability. Furthermore, three dimensional properties of vortex shedding around the cable must play important roles in these mechanisms.
