Corrosion effects on the mechanical properties of reinforcing steel bars: fatigue and s–e behavior

Corrosion of steel reinforcement is one of the most severe problems of durability in reinforced concrete structures. A good understanding of the corrosion effects on the reinforcing steel mechanical properties is necessary to adequately assess impaired structures. A study of the mechanical response...
