| Abstract: | The corrosion of steel transmission towers can lead to changes in loadcarrying performance of steel transmission towers, which causes a security risk for the transmission lines. With the example of Guangxi Power Grid, combination of in-service reliability of transmission line tower identification methods, finite element method was used to conduct a structural analysis of the corroded steel transmission tower so as to provide a safety assessment method for such tower. |
