Steel Reinforcement Section Loss Guidance Tables

Strength and durability of reinforced concrete (RC) bridges are adversely affected by deterioration of their structural members. When investigating bridges in need of maintenance and repair, deterioration caused by corrosion of steel rebars is commonly found as one of the primary sources of structural degradation. To ensure the safety of bridges, while reducing direct and indirect costs, an accurate estimate of the extent of reinforcement section loss has a central importance for a wide spectrum of engineers and decision-making authorities. Such estimates can be achieved through a systematic effort that benefits from the wealth of available predictive models calibrated with region-specific data and then validated through appropriate field investigations.
