In this paper, a tuned mass damper is applied to improve the seismic performance of the lighting tower. The light tower has a high slenderness ratio, low lateral stiffness and top mass is large structure so this has weak for vibration characteristics. The optimized damping coefficient and stiffness were applied to the four lighting tower models analyzed. As a result, the light tower with TMD showed a tendency to reduce the displacement response significantly against the earthquake.
