Abstract:
A measured fatigue load model, tailored for the Beijing-Tianjin-Hebei region, was developed using dynamic weighing system(WIM). In addition, fatigue experiment were performed on orthotropic steel bridge decks. The findings of this study reveals that fatigue crack tend to initiate at the weld toes between deck and U-rib, developing along the thickness direction of deck. the stress near the fatigue crack significantly decreases after redistribution, resulting in a reduced bearing capacity of the structure. Furthermore, the position of the fatigue crack suggests that welding residual stress has a crucial role in the structural fatigue failure process. © 2023 SPIE.
