抄録
Crevice corrosion between gusset plate connections and the flanges of diagonal members remains an unknown phenomenon. In this work, gusset plate connection, flanges of diagonal members and additional reinforcement plates were removed from a dismantled bridge for crevice corrosion measurements. The contact surfaces of two gusset plate connections, one standard upper connection and one lower connection with reinforcement, were measured in detail using laser equipment. From the results, the actual crevice corrosion state of these members were evaluated and graphs of corrosion depth distribution produced.
