Fatigue Behavior of Weathered Steel Bridge Components

摘要

A total of 176 specimens with transverse stiffeners or 102-mm (4-in) attachments were fatigue tested as they were originally fabricated, after they were weathered two years, and after they were weathered four years. It was found that weathering reduced the fatigue life of the stiffeners as much as 22 percent, and the life of the attachments as much as 10 percent, as compared to their nonweathered counterparts.
