  • INFLUENCE OF LOAD RANGE ON FATIGUE CRACK PROPAGATION BEHAVIOR FROM WELD ROOT BERWEEN STEEL DECK PLATE AND TROUGH RIB

抄録

From around 2000, fatigue cracks originating from weld roots between trough ribs and deck plates have been detected in the vicinity of the intersection to lateral ribs of steel plate decks. The authors made clear the fatigue crack initiation and propagation behavior from the weld root into deck plate and suggested that thickening the deck plate and installing scallop made fatigue durability high. In the study, load range of 50kN which was larger than actual wheel load was used for fatigue tests on model specimens. In this study, fatigue tests on the specimens same as the previous one have been performed under load range of 35kN, and an influence of load range on fatigue crack initiation and propagation behavior has been discussed.
