Abstract: To effectively evaluate the impact of corrosion on the bearing capacity characteristics of long-term service towers, scanning electron microscopy, tensile testing, axial compression bearing capacity testing, and simulation methods were used to study the effects of different degrees of corrosion on the corrosion rate, yield strength, tensile strength, elongation after fracture, elastic modulus, and bearing capacity of tower components. The research results indicate that the yield strength, tensile strength, and elongation after fracture of tower components will decrease nonlinearly with the increasing corrosion degree, while the elastic modulus is basically not affected by corrosion. The greater the cross-sectional loss rate, the lower the bearing capacity of the component. The effect of corrosion at the middle position is greater than that at the edge position.
