It is necessary to develop the damage function to cope with the increasing damage of steel transmission towers. A simplify analysis to evaluate the performance resistance capacity, which is essential for the development of the damage function, was performed. The 154kv power transmission towers installed between Sokcho and Yangyang were selected as the target structures. Wind loads were calculated and applied to the target structures according to the domestic transmission and distribution facility design standards. As a result of this study, displacement according to wind speed of the target structure was derived.
