| Abstract: |
This study investigated fatigue strength evaluation methods based on the structural hot spot stress concept, focusing on a crack at a crossing between a longitudinal closed rib and a cross-beam (transverse rib) web cutout in an orthotropic steel bridge deck. The results indicated the possibility that the fatigue strength of the connection can be evaluated with the hot spot stress range. And also, it was revealed that the hot spot stress range hardly decreases with increasing of deck plate thickness and decreasing of transverse rib distance. |
