%X 通过对福州市城市桥梁交通荷载和运营车辆的装载情况调查，得到由32类日常典型的运营车辆组成的荷载频值谱，以及货运车辆的空载率. 根据等效疲劳损伤原理将所得到的荷载频值谱简化为由6辆疲劳荷载模型组成的具有实用性的荷载频值谱. 进一步分析得到一辆适宜验算桥面系构件的标准疲劳车辆荷载模型. 所得到的疲劳荷载频值谱和疲劳车辆荷载模型，可以供城市钢桥疲劳损伤验算参考.<br>Through investigating the traffic loads of city bridge and loading conditions of vehicle operators in Fuzhou，obtained a load frequency value spectrum which including 32 types of daily vehicle operators and the empty-loading ratio. According to the theory of equivalent fatigue damage，we can simplified the frequency value spectrum to the practical one by 6 consists of the fatigue load models. After further analysis of vehicle load，we can set up a standard fatigue-loaded vehicle model which is suitable for checking component of deck system. This can be used as references for bridge fatigue damage calculation or fatigue design of other steel bridges in Fuzhou
