“…The corrosion of structural steels, including weathering steel, is examined in [2][3][4][5][6][7][8][9][10][11]. In [2], it is shown that the primary products of atmospheric corrosion of regular or low-alloy steel are crystalline and amorphous rust (FeOOH) and magnetite (Fe 3 O 4 ).…”

“…Effectively, A is related to the initial reactivity of the steel, while B accounts for the change in corrosivity of the steel over time. Other corrosion penetration equations for weathering steel are proposed and evaluated in a number of references, for example: [10,11]. Although the merits of each model can be argued, Eq.…”

“…Therefore, the effect of corrosion should be considered when analyzing the bearing capacity of transmission towers. The degree of atmospheric corrosion of steel has a quantitative relationship with environmental factors and the chemical composition of steel [22][23][24]. Therefore, the corrosion rate of steel can be predicted according to the measured data.…”

To investigate the variation law of the wind-resistant performance of transmission towers during their operation, this paper proposes an evaluation method for the wind resistance of the transmission tower considering corrosion, and a 220-kV transmission tower is analyzed as an example. Considering the uncertainty of the material and geometric parameters, the wind-induced collapse of the transmission tower was analyzed, and the collapse wind speeds were obtained via pushover and incremental dynamic analyses. In addition, the sensitivity of the transmission tower to various parameters was analyzed. Based on the existing meteorological and corrosion data, corrosion prediction models were established using a back-propagation (BP) artificial neural network, and the mean relative error between the predicted and measured values of the test samples was 8.91%. On this basis, the corrosion depth of the tower members in the four regions was predicted, and the fragility of the transmission tower was analyzed considering the effects of corrosion and strong winds. The results show that the collapse wind speed of the transmission tower is most significantly affected by the thickness of the angle steel, followed by the elastic modulus and yield strength, and is less affected by the width of the angle steel. When the exposure time was 25 years, the wind-resistant performance of transmission towers in regions with severe acid rain and coastal industrial regions decreased by 10% to 20%. With an increase in exposure time, the failure mode of the transmission tower tended to be brittle failure.
