This study examined procedures to evaluate the effect of commercial vehicles including overload on fatigue damage of highway structures. A method of classification in that load status was classified into empty, loaded and overloaded with pattern patching technique and load specifications was proposed. The classified vehicle load data was applied a fatigue damage model. Percentage of fatigue damage caused by each load status was calculated.

这项研究考察了评估包括超载在内的商用车对公路结构疲劳损伤的影响的程序。提出了一种基于模式修补技术和负荷规范的空载、载重和超载三种负荷状态分类方法。将分类后的车辆载荷数据应用于疲劳损伤模型。计算了每种载荷状态引起的疲劳损伤百分比。
