摘      要：Reinforcement corrosion directly affects the mechanical behavior of reinforced concrete *** electric corrosion test was conducted on a reinforced concrete test specimen,and a finite element model of the reinforcement corrosion damage was *** addition,the damage behavior of reinforced concrete under different corrosion sediment distribution characteristics and different corrosion rates was *** was noted that when corrosion sediments are in a“semiellipse+semicircledistribution,the results of numerical calculation are consistent with those obtained experimentally,reflecting the damage characteristics of reinforced concrete test ***,the results showed that the distribution characteristics of corrosion sediments greatly influence the damage behavior of reinforced *** particular,when the corrosion sediments demonstrate a“semiellipsedistribution,reinforced concrete members may easily suffer from reinforcement *** the case of“semiellipse+semicircleand“circledistributions,the cohesive force between the reinforcements and concrete decreases:With the same corrosion rate,the damaged area expands with the increase in the number of reinforcements,which indicates a reduction in the cohesive force and thus,a reduction in the damage in the reinforcement *** paper analyzes in-depth the effects of reinforcement corrosion expansion on the concrete damage behavior,provides references for practical engineering.
