Abstract

Abstract

The experiment of bond of beam elements subjected to deicer-frosting cycles was carried out and the effect of deicer-frosting cycles on the bond characters between reinforcement and concrete was studied.Based on the experimental results, the bond mechanism of reinforcement and concrete after deicer-frosting cycles was explored, and the degradation rule of bond strength and the model of bond-slip relationship were developed.
- reinforced concrete,
- deicer-frosting cycles,
- bond strength,
- bond mechanism,
- constitutive relation
