What do we know about concrete, steel, and bond-slip relation for corroded bars?
Paper in proceeding, 2020

Reinforcement corrosion influences the deformation and load capacity of steel rebars. Further, it generates splitting stresses that weaken the concrete and strongly affect the bond between reinforcement and concrete. Here, a recently published engineering model to determine the deformation
capacity of rebars with pitting corrosion is described. Further, the effect of corrosion on bond is described in a systematic way, with an overview of the effect for various cases depending on reinforcement type, existence of transverse reinforcement, and confinement due to concrete and boundaries.
Finally, an engineering model to determine bond-slip relationships for ribbed bars is presented.
