Abstract
Aerodynamic vibration of stayed cables, especially rain-wind induced cable vibration, has been a rather serious problem on the design of cable-stayed bridges. This well-known phenomenon occurs at particular high reduced wind velocity regions and under raining condition. From results of wind tunnel tests, it might be explained as a vortex-induced vibration, which occurs at limited high reduced wind velocity. Then, in this study, the effect of non-uniform water rivulet on the vortex-induced vibration at high reduced wind velocity is investigated by wind tunnel tests. The artificial rivulet is non-uniformly attached on a rigid cable model along the axis. Under various combinations of rivulet location, the velocity restricted response, which is similar with the observed response of the prototype inclined cables in rainy day, is obtained for the symmetrical combination of rivulet location. The conclusion is that the rain-wind induced vibration would be caused by the span-wisely non-uniform and particular locations of upper water rivulet on a cable surface.
