A Study on the Full Scale Structural Test of High Voltage Electric Transmission Tower

초고압 송전철탑 구조성능시험에 관한 연구

Full scale structural test of 765kv electric transmission tower was performed to measure the stresses and displacement of towers under the design loadings, and the results were compared with analytical results based on three dimensional frame analysis. Also, the actual ultimate strength of the tower was measured through destructive test. Especially, to predict the behavior and failure of the connection of tubular member, finite element analysis was performed and compression test for the segments of tubular member were carried out. Valuable information for the overall and local behavior of the tower was obtained and reliability of current analytical method was confirmed.
