Paper Summary

Steel bridges are experiencing more fatigue due to heavier traffic. Recent research focused on fatigue cracks in orthotropic deck structures. The study examined welded details and found that failures were due to poor fabrication and detailing. Recommendations were made to reduce the risk of fatigue failures in steel bridges.
