Development of Corrosion Prediction Software for Designing Weathering Steel Structures with Semi-Eternal Service Life

摘要

Needs for minimum maintenance materials for infrastructure, such as weathering steel are growing. Since corrosion rate of weathering steel is much lower than plain carbon steel, it is possible to construct durable steel structures without painting, or plating, which reduces life cycle cost of the structures to a great extent. To realize this conception, it is very important to select the best alloyed weathering steel, in accordance with corrosiveness of the atmosphere at construction sites. In order to facilitate such assessing processes, long-term corrosion prediction software for weathering steel has been developed.
