摘要：
The cracking character is an evaluation index on the serviceability limit state of the reinforced concrete (RC) structure. 37 RC beams with different type reinforcement bars and ratio of reinforcement were made in the laboratory. The corrosion of reinforcement in RC beams was realized by accelerated electrochemical test. The corrosion ratio was controlled by the electric current density and time. The cracking character of the corroded RC beam in the static load test was discussed. Based on comparison between calculation results according to Code for design of highway reinforced concrete and pr...
