Abstract
It is important to evaluate the amount of airborne sea salt adhered to each member of a bridge accurately and quantitatively for effective maintenance and management, because airborne sea salt have large influence on their durability especially at coastal regions. On the other hand, local governments have to maintenance and manage many bridges simultaneously. Therefore, it is preferable to obtain corrosion environment of each bridge without any on-site observation and/or monitoring to conserve their budget.<br> First, in this paper, the authors calculated wind speed, wind direction and airborne sea salt concentrations using the meso-scale atmospheric model WRF. Second, the study bridge and the simplified surrounding topography were realized in computational domains to calculate steady flows in each approaching wind direction using the CFD technique. Finally, in addition to these results, on the basis of the proposed quantitative evaluation method of the amount of airborne sea salt on a surface, the authors evaluated the salinity amount in vicinity to each member of the study bridge. The authors achieved a certain result to regard with the WRF simulation and the evaluation of the salt amount, and expect that more accurate estimation will be realized with some improvements.
