“Corrosion reduces the strength of a high strength steel cable in a suspension bridge by decreasing its effective cross-sectional area and introducing stress concentrations. As the steel converts to rust, which is weaker and less dense than the original material, less steel remains to carry tensile loads, directly reducing the cable's load carrying capacity. Corrosion also creates pits and surfaces irregularities that act as stress concentrators, significantly raising stress levels in the remaining sound steel and making it more prone to fatigue and fracture. Because of this combination of reduced area and localized stress concentration, even relatively minor corrosion can meaningfully weaken a high strength cable and threaten the overall stability of suspension bridge.”
