Abstract
A series of wind tunnel tests was conducted using a circular cylinder with various skew angles, so that the characteristics of the large-amplitude vibration of stay cables at high wind speed can be clarified. Cases with skew angles of 0, 40, 45, 50, and 60 degrees were tested where the aspect ratio was between 10.4 and 20.7. Response with large amplitude beyound 2D and strong negative aerodynamic damping was observed with skew angles 40, 45, and 50 degrees. It was thought to be the point to reproduce the vibration that the flow particularly around the windward end of the model is not disturbed. At the wind speed in critical Reynolds number, random vibration was observed probably due to asymmetric separation from the model.
