| 摘要： | This paper investigates the effects of deterioration due to corrosion on monotonic and cyclic bond performance. Forty-two monotonic and cyclic pullout tests were undertaken on well-confined corroded reinforced concrete specimens, with corrosion levels ranging from 0 to 25％ reinforcement mass loss. Experimental results were used in the development of a corrosion-dependent cyclic bondslip model that recreates the effects of corrosion on reinforcement bond. The model allows for alteration of the monotonic pullout curve along with altered damage relationships under cyclic loading to account for corrosion of reinforcement. Impressed current techniques were used to achieve the desired level of corrosion, and the results of this research provide a term of comparison for future studies on specimens subject to natural corrosion processes. |
