Dew condensation is an important factor in the occurrence of bridges corrosion and contributor to the deterioration of protective coating. Therefore, it is important to prevent from occurrence of dew condensation in steel bridges. In this study, the wind influence to prevent dew condensation was investigated by using computational fluid dynamics (CFD) technique, and the investigation outcome confirmed the validity of proposed technique to a certain extent.
