内容記述
A lot of fatigue cracks have been reported in welded joints between steel deck plates and vertical stiffeners of orthotropic steel deck. As countermeasures against these fatigue cracks, UIT (Ultrasonic Impact Treatment) which is one of the peening methods and applies to the weld toes as for small fatigue cracks existing along the weld toe, and Stop Hole method as for the fatigue cracks which extends to deck plate were taken up. In this study, for the purpose of making clear the effect of these repair methods, fatigue tests and stress analyses on model specimens have been performed. Furthermore, examined on application of theserepair method for actual bridge.
