Practical repairing methods for fatigue damage in cross bracing connections in steel girder bridges are studied experimentally. Fatigue cracks initiated in the welded joint between upper flange of longitudinal girder and transverse stiffener to which cross bracing is connected. Various repairing methods are examined and the increasing weld size with TIG dressing is proposed as one of the most suitable repairing method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
