Abstract
AbstractOrthotropic steel decks (OSDs) are easily subjected to fatigue cracking under the cyclic vehicle loading, and arc notch between diaphragm and U-rib is one of the typical fatigue details. The strain values of three measuring points at arc notch in a steel bridge were monitoring to obtain the stress time histories. Then, fatigue stress amplitudes and fatigue damage degrees were analysed. It was found that this typical fatigue detail was under tension–compression cyclic stress. The maximum stress amplitude appeared at U-rib weld toe, which indicated that fatigue cracks were more prone to propagate on this area, comparison of fatigue damage degrees also corroborated it.
