It is necessary to evaluate the salt amount in each member of a bridge for effective maintenance. The dry gauze method is authorized well in Japan, while its collecting efficiency of salt particles has not sufficiently been clarified. The authors evaluated air flows around a device of the dry gauze method by wind tunnel experiments. It turned out that the flow pattern around the device depended on approaching wind speeds and wind directions. This implies that the collecting efficiency also depends on wind conditions. Additional experiments, CFD calculations, and on-site observations will be conducted in the future.
