The complex cable aerodynamics has being studied by many researchers. The traditional vibration of stay cable caused by rain-wind combination has been known as most typical type and many kind of countermeasures has been proposed for suppressing this kind of vibration. Recently, stay cables were proved that they could be vibrated not only in rain-wind condition but also in dry state. Some of authors have pointed out the significant role of an axial flow in a wake of inclined/yawed cable for galloping instability. In this study, dry-state galloping was investigated by a wind tunnel test with various kinds of relative wind angles and three types of counter- measures have been proposed to suppress dry-state galloping of stay cable.
