Fatigue Evaluation Approaches of Welded Joints on Orthotropic Steel Bridge Deck

    摘要
  • 摘要: 传统正交异性钢桥面板疲劳性能评价方法评估精度不足,为准确评估其焊接接头的疲劳性能,基于线性累积损伤理论,探讨了结构应力法、切口应力法用于正交异性钢桥面板焊缝疲劳性能评估的可行性和准确性.以典型正交异性钢桥面板为研究对象,采用足尺模型试验和仿真分析,并结合已有试验数据对上述评估方法进行验证.研究结果表明:与结构应力法相比,采用切口应力法或传统名义应力法评价正交异性钢桥面板的疲劳性能时,评价结果的离散性大;采用结构应力法(离散度为3倍标准差的主S-N曲线时)更准确,适用于正交异性钢桥面板焊接接头疲劳性能评估.

     

    Abstract: The traditional fatigue evaluation approach for orthotropic steel bridge deck is not sufficiently accurate. To accurately evaluate the fatigue properties of welded joints on a orthotropic steel bridge deck, the validities and accuracies of the structural stress method and the notch stress method were investigated based on the liner cumulative damage theory. By taking a typical orthotropic steel bridge deck as an investigated subject, the evaluation methods were discussed by a full-scale segment model test and numerical analysis, and they were verified by the data from the existing full-scale model fatigue tests. The research results indicate that compared with the structural stress method, the notch stress method and the traditional fatigue evaluation approach have high data scatters. The structural stress method may be suitable to the fatigue evaluation of welded joints on a orthotropic steel bridge deck under the condition that the data scatter of a master S-N curve is three times of standard deviation.
