【 摘 要 】

The safety of transmission tower structure is an important guarantee for the reliable operation of the transmission and distribution line. Furthermore, the perennial corrosion of steel components greatly weakened its ultimate bearing capacity, which is a huge detriment to the structural safety. Based on Analytic Hierarchy Process, the tower was divided into four layers and the components were classified into three categories. Corrosion allowance was used to define security index so that hierarchical and structural safety could be calculated.
