Abstract
This study aims to clarify the generation mechanisms of rain-wind induced vibration of cables on cable-stayed bridge by wind tunnel test. The detail vibration mechanisms have not solved yet, because of the complex flow condition around the cable, which is caused by the cable inclination and the water rivulet. In recent research, it is often thought that the moving water rivulet plays an important role on the inclined cables vibration. For the purpose of investigating the effect of the moving rivulet, we measure unsteady aerodynamic force on the assumption that cable torsional motion is equal to the rhythmic movement of the water rivulet. We also compare lift force calculated from aerodynamic derivatives to the one from quasi-steady theory, and we investigate the characteristics for various positions of water rivulet.
