This study deals with the aerodynamic control of bridge tower. Generally, Bridge tower consists in about two years alone constructing bridge, it is important to consider the dynamic response of a bridge tower to the wind load including the aerodynamic instability such as vortex-induced oscillation and galloping phenomenon. Moreover, as galloping effects on destruction of structures, this phenomenon must be controlled. The method of aerodynamic control using this paper is corner cut. Using corner cut, minimizes the separate flow and drag force coefficient, therefore controls the response. In this paper, the experimental study to the response of the 2-D rectangular sections is conducted varying the width to depth(B/D) ratio and corner cut size. Based on the results obtained, the study to response of the structures applying corner cut is performed. By using the elastically supported model, behaviors related to velocity of wind, the responses are measured. At first, corner cut applys to the perpendicular members for the flow direction, and then the inclined members for the flow direction. Aerodynamic motions are observed in galloping when B/D ratio is greater than 0.8, but using effective corner cut, it is perfectly controlled or considerably raised the galloping occurrence velocity in perpendicular members and inclined members. Especially, as B/D ratio is increased, it is observed that the application of corner cut is effective.
