Abstract:

Fatigue is a common and potentially very damaging occurrence in metallic structures, including steel bridges. There have been numerous studies throughout the last two centuries on fatigue life, but challenges of preventing fatigue crack growth are still unresolved. The most widespread method of repair and retrofitting involves drilling a crack-arrest hole at the tip of a fatigue crack, but crack re-initiation has been noted in many cases of this repair. The purpose of this study was to better understand re-initiation at crack-arrest holes through welds and to develop methods to prevent re-initiation from occurring.
