The bridge as one of social infrastructure is used for long time. In order to make the bridge with durability, it is necessary to make the bridge without using additional members such as fairing so on as the stabilizing members under wind effect. The vibration induced by wind is generated by the separation at the windward point of the bridge. The method to control the separation by the separation is the Separation Interference Method which is developed by the supervisor of the present research. It was concluded that Separation Interference Method enabled to make the bridge girder with good performance to the wind effect.
