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.

Recently, the damage caused by typhoons and strong winds, which frequently occur as a result of global climate change, is on the rise. Soundproofing and windshield walls installed on roads often fail to function because of damage due to strong winds. Therefore, in this study, strong wind fragility evaluation was performed to predict the probability of failure of soundproof / windproof walls from wind loads. A three-node bending experiment was carried out to investigate the material characteristics of the aluminum frame which was installed on the actual soundproof wall. Based on the results of this experiment, the resistance performance of target structure was calculated, and the frame damage was selected as the performance limit state. Wind loads acting on 4m x 1m individual element soundproof wall was compared with the resistance capacity by Monte Carlo simulation method. In the future, the evaluation of the strong wind safety of the sound barrier structure should be proceeded by setting the limit state and performing the vulnerability evaluation through the additional experimental data. This work can become guideline information for future design of soundproof and windproof wall.
