영어 초록

In this study, the fragility for transmission tower subjected to wind disaster, which has the greatest influence on transmission tower, was developed for 154kV transmission tower located between Yangyang and Sokcho city. The resistance capacity and the limit state required for the evaluation of the fragility were divided into the major part and the auxiliary part in the steel tower. Moreover, the failure of tower was defined as the yielding stress of each member in the tower which could be used to determine their resistance performance. Domestic wind design guideline and criteria for transmission tower was used to determine the wind loads demand on the tower. By comparing the loading demand and resistance capacity, the failure of tower could be determined which in turn used to derive the wind fragility. The results obtained in this study could be used as a reference for damage prediction system of transmission tower and similar structures.
