Structures are known to incur damage from airborne sea salt adhesion; especially, steel structures exposed to open air, such as sports stadiums, in coastal areas are considerably damaged due to airborne sea salt adhesion. In this study, the relationship between the corrosion damage due to salt adhesion and the detailed airflow distribution around a large sports stadium was investigated using computational fluid dynamics (CFD). First, the prediction accuracy of the flow field using CFD, which is an important premise for accurate salt adhesion estimation, was carefully validated by quantitatively comparing it with wind tunnel measurements in detail. Next, a CFD-based method that estimates salt adhesion resulting from wind flow was developed and applied to a large sports stadium using local meteorological data. Finally, the estimated salt adhesion results were compared with the field survey results of corrosion damage, and the estimation accuracy of the proposed approach was evaluated. The areas with high adhesion, as predicted by the CFD simulation, were in good agreement with the areas where the corrosion damage actually progressed, except for a few exceptions. The proposed estimation approach was confirmed to be useful in considering the effective countermeasures against corrosion damage in complex structures.
