Abstract
The aerodynamic vibration of stayed cables, especially rain-wind induced vibration, has been a fairly serious problem for the design of cable-stayed bridges. Form the results of wind tunnel tests, this vibration seems to be caused by some peculiar reasons such as the upper water rivulet formation on cable surface, the axial flow in a near wake of an inclined cable, and the 3-D von Karman vortex shedding along the inclined cable axis. However, the detailed mechanisms of vibration have not been obtained yet. This research aims to clarify the effect of the Karman vortex shedding on cable aerodynamic characteristics. Wind tunnel tests have been carried out for two cable models with horizontal yaw angle 0 degree and 45 degree respectively. The effect of Karman vortex shedding on galloping characteristics of cable model has been studied.
