近年来,随着我国汽车产业不断发展,中国已经成为拥有世界上最多车辆的国家。车辆的反复行驶对公路桥梁已经产生了长期的疲劳荷载,这将会对公路桥梁产生很大的损害,甚至发生断裂。基于这种情况,分析了影响钢结构桥梁使用寿命的影响因素,不断优化在公路钢结构桥梁设计中对桥梁的疲劳设计,对公路钢结构桥梁的疲劳设计方法以及相关要点进行了阐述。
In recent years, with the continuous development of China’s automobile industry, China has become the country that owns the largest number of vehicles in the world. Repeated driving of vehicles has produced long-term fatigue loads on the highway bridges, which will cause great damage to the highway bridges and even rupture. Based on this situation, the influential factors that affect the service life of the steel structure bridges are analyzed, the fatigue design of the bridge in the design of the highway steel structure bridges, the fatigue design methods of the highway steel structure bridges and the related points are continuously optimized.
