Many steel structures are faced to the problem of deteriorati on in Japan. Deterioration of the coating due to dew condensation causes corrosion of steel bridges. Therefore, it is necessary to develop a technique for preventing dew condensation. In addition, dew condensation is deeply related to the girder. In this study studies on prevention of dew condensation by paying attention to the temperature of girder were carried out. Heat insulating coating and heat storage material were used to prevent dew condensation. As a result, it was found that technique to prevent dew condensation is effective.
