Abstract
In this paper, it is reported that the wind tunnel test on parallel cables was carried out by using full sized models. And, the incidence of the wake galloping was confirmed on the original model. So, authors tried to make a study to solve this problem with two measures. Firstly, helical wires were winded for the cables in a spiral configuration as an aerodynamic measure. Secondly, some damping was added to the cable using of oil damper equipments. As a result, by setting of the helical wire or additive damping, it is confirmed that the amplitude occured from wake galloping is able to be restrained until the max wind speed in this test. In addition, the pressure features of cable surface and aerodynamic damping data on wake galloping could be obtained in this test.
