Abstract

This paper aims to investigate the effects of the reinforcement corrosionon the residual bond strength behaviour of corrosion damaged reinforced concretestructures in natural corrosive environments. The analytical solutions of residual bondstrength of corroded concrete structures are used to evaluate the bond behaviour ofUllasund bridge, Norway, which was demolished in 1998. The results obtained from thestudy have been examined with the published field data. The study concludes that thebond strength in concrete increases in low level of corrosion (<1%) and decreasessignificantly with further increase in corrosion due to longitudinal cracking of theconcrete cover. The proposed approach is capable of assessing the bond strengthbehaviour of corrosion affected concrete structures.
