This paper focuses on the detrimental effects of wildfires on steel structures within the power industry, specifically examining the degradation of mechanical properties in structural materials and protective coatings due to high-temperature exposure. It discusses the impact on transmission and distribution structures, as well as the generation of gases and corrosive substances during wildfires. Furthermore, the paper investigates the influence of high temperatures on the mechanical properties of bare structural steel and the degradation of galvanized steel coating layers. Additionally, it explores the thermal degradation of organic coatings, changes in concrete mechanical properties, and the application of non-destructive techniques for condition assessment, including remote temperature monitoring, on structures exposed to wildfires. This research provides valuable insights into the effects of wildfires on power industry steel structures, enabling better understanding and the development of effective mitigation strategies to safeguard infrastructure and ensure its resilience in fire-prone areas.
