| Abstrakt: |
Steel is an economical choice for bridge construction for a number of reasons, including its high strength, its light weight, as well as its resiliency in the face of extreme weather events or natural disasters. Duplex zinc coatings for steel structures consist of a metallic zinc coating, typically hot dip galvanized (HDG) or thermal sprayed zinc (TSZ), painted with a protective organic coating. The time to first maintenance of a duplex coating can easily be twice the life of the individual metallic zinc and paint coatings alone. Life-cycle cost modeling compares material and design alternatives over the entire life of the structure. Life cycle costs models have shown the benefits of using duplex zinc coatings for corrosion protection to reduce the total cost of ownership of steel bridges, as well as to show that steel bridges are competitive with concrete structures for short spans. |
