Rainfalls or dew condensation are one of corrosion factors of steel bridges. Since surface temperature distribution of steel bridge varies depending on the composition and or directions of steel members or meteorological factors taken into account, it is difficult to grasp precisely the condition of dew condensation of the steel members. Even in the past, there was a scarce study made in detail regarding wetted time/hours or corrosive environment. We made a study on the characteristic of dew condensation of steel members in view of surface temperatures of respective steel members and dew point as derived from atmospheric temperature and relative humidity adjacent to the steel bridge. In addition, we made a study whether it is possible to evaluate the characteristic of dew condensation of steel members by corrosion current derived from an ACM sensor.
