A significant percentage of the cost incurred by society due to the deterioration of existing civil infrastructure can be attributed to the fatigue and corrosion of steel bridges. In many parts of the world, the deterioration of steel bridges due to fatigue is accelerated by increasing traffic volumes and vehicle weights.

由于现有民用基础设施的恶化而产生的社会成本的很大一部分可以归因于钢桥的疲劳和腐蚀。在世界许多地方，由于交通量和车辆重量的增加，钢桥因疲劳而加速老化。
