Monitoring of Traffic Axle Loads for Fatigue Environment in Orthotropic Steel Deck Structures

提出了轴载荷的计算方法。该方法采用正交各向异性钢甲板结构在重型车辆通过时的应变响应。将该方法应用于三辆轴重分别为207.6kN、310.1kN和411.3kN的重型卡车的整车运行试验。共85个轴道，平均误差为-2.1%，误差标准差为6.7%。对某实际正交各向异性钢甲板结构进行了一周连续监测，结果表明，100kN以上轴载通过1793次，200kN以上轴载通过31次。

A calculation method of axle loads was developed. The method uses strain responses of orthotropic steel deck structures when heavy vehicles pass. The method was applied to a vehicles running test with three heavy trucks, the axle weights of which are 207.6kN, 310.1kN and 411.3kN. In total 85 axle passages, the average error was -2.1% and the standard deviation of the errors was 6.7%. For one-week continuous monitoring data in an actual orthotropic steel deck structure, the result showed axle loads over 100kN passed 1,793 times and those over 200kN did 31 times.
