Abstract
Recently, cable-stayed bridges get larger and longer. As a result of this, aerodynamic instability of stay-cables becomes obvious. For instance, dry-state galloping, rain induced vibration, flutter and so on. It is pointed out that dry-state galloping in stay-cables is caused by the suppression of Karman vortex. But the mechanism of it is not clarified yet. For that reason we must examine it in detail. It is known that end conditions of the inclined cable model have great influence on the results of the experimentation in wind tunnel. Therefore, in this study, we adopt the cable model which can measure the aerodynamic forces partially in order not to be influenced by the end conditions. We consider the occurrence of dry-state galloping in stay-cables by using the cable models which have various kinds of surface configuration in order to suppression of Karman vortex.
