The durability of the steel structure can be affected by atmospheric corrosion environments as temperature, humidity, airborne salt etc.. However, atmospheric corrosion environments can be locally changed depending on structural condition and shape. To estimate the local atmospheric corrosion environments depending on structural member exposed to the marine environment, corrosion level of structural member in steel bridge was examined from exposure tests.
