Abstract:

This study investigated how the shear capacity of reinforced concrete bridge beams is affected by corrosion damage to the shear stirrups. It described the changes that occur in shear capacity and concrete cracking as shear stirrup corrosion progresses. Visual signs of corrosion distress were correlated with structural performance of large-size reinforced concrete beams that were corroded to four damage states. The corrosion products and damage were characterized for the beams and compared to field beams. Analysis methods incorporating quantified corrosion damage predicted reasonably well the shear capacity of the large-size beams. Recommendations were presented for improved inspection practice to allow for estimating shear capacity of corrosion-damaged sections in reinforced concrete bridges.
