Abstract:

Drilling crack-arrest holes to halt fatigue crack propagation is a simple technique that is commonly used by bridge owners controlling and/or repairing fatigue cracking in steel bridges. Well-established relationships exist for sizing the diameter of the crack-arrest holes for in-plane fatigue loading; however, the effectiveness of crack-arrest holes under out-of-plane (distortion-induced) fatigue is not well understood.
