In the decades, orthotropic steel bridge decks were experienced a variety of fatigue problems from wheel load cycles and welding quality of welded joints. The crack initiation at the weld root between deck plates and U-rib was considered as one of the most serious cracks. In this study, fatigue tests and finite element analysis were conducted. In fatigue test results, the failure at the weld root shown to be easier than weld toe. Increase the penetration rate is better for reduction of stress range and stress concentration at weld root. In addition, the specimen with a changed thickness from 12mm to 16mm led to the decrease of stress range. A thicker deck plate would own a longer fatigue life before crack initiation, which was agrees with the results of tests. |
