【Abstract】 Atmospheric corrosion is one of the main factors which cause the damage of steel structures. It varies with time and the reliability analysis considering corrosion is time variant reliability, while the model of the corrosion affects the reliability analysis significantly. The carbon steel and low alloy steel are the main material of steel structures. So after the brief description of its mechanism of corrosion and process, the current used model of atmospheric corrosion were presented here for reference of the evaluation of the reliability of steel structures.更多还原
