FATIGUE BEHAVIOR OF WELDED WROUGHT-IRON BRIDGE HANGERS. Conference Paper

abstract

• The behavior of fatigue crack growth and fatigue strength of welded lap splice wrought-iron hangers in a railroad bridge was studied. The original wrought-iron hangers were lap spliced with steel plates for the purpose of tightening the members. Field inspection revealed cracks in the welded lap splices. Examination of simulated test joints and cracked hanger splices in the laboratory indicated that fatigue cracks would develop from weld deposits at the cut of the wrought-iron bar, propagate into the steel splice plate, and cause failure.
