[I-367] INVESTIGATION OF DEW CONDENSATION ENVIRONMENT OF A BRIDGE IN MOUNTAINOUS AREA
キーワード：鋼橋、結露環境、維持管理
It is important to accurately evaluate corrosion environment of steel bridge for an appropriate corrosion prevention and maintenance management. This research aims to evaluate the corrosive environment of a steel bridge constructed in mountainous area on-site by field measurement. Hence, Evaluation of dew condensation as a results of air temperature and relative humidity which is one of the fundamental corrosion factor of steel bridge was carried out at Toyokuni bridge. The outcome of present investigation revealed that the dew can easily occur in mountainous area and confirmed the corrosion environment.
