Mechanical model for the shear strength prediction of corrosion-damaged reinforced concrete slender and non slender beams

Steel corrosion in RC structures leads to a reduced reinforcement area, changes in steel mechanical properties, cracking and, eventually, concrete cover spalling, among other phenomena. Stirrups are generally small in diameter and, given their small concrete cover, they are more susceptible to corrosion than longitudinal reinforcement. Hence their corrosion significantly affects shear strength. Most existing models that deal with reduction in...
