ABSTRACT

ABSTRACT: A study is conducted to find an anti-corrosion strategy for the effective maintenance of steel structures in the coastal areas on the basis of corrosion exposure tests on a rolled H member. The steel cross section is hypothetically assumed to be reduced at a constant corrosion speed. Basic comparisons are made between a titanium-clad steel specimen and specimens with different paint coatings in consideration of the cost and lives of expectancy assuming a constant corrosion speed for the steel. It was found from the comparison that the least life cycle cost at 100 years from the construction was found when the fluorine resin coating is chosen and the repainting is made at every 30 years and the member is replaced once with the new member. Furthermore, it is found that the titanium-clad steel could be the most economical choice if the unit price could be reduced by 50%.
