| 摘 要： | 将九江长江公路大桥实测的21类日常典型的运营车辆组成的荷载频值谱，依据等效疲劳损伤原理，简化成由7类模型车辆组成的具有实用性的荷载频值谱，该结果对类似的其他公路钢桥的疲劳损伤度验算具有一定的参考价值；所建立的疲劳荷载车辆模型，可供九江其他市桥梁疲劳损伤验算或疲劳设计时参考。

| Abstract: | According to the principle of equivalent fatigue damage,the load frequency spectrum composed of 21 types of daily transport vehicles obtained by the traffic survey at the Jiujiang Yangtze river bridge is simplified into a practical one composed of 7 types of model vehicles. The results can be used for fatigue assessment of other highway bridges with the similar components of daily vehicle traffic. This fatigue-loaded vehicle model can be used for fatigue assessment of other highway bridges in Jiujiang city. |
