摘要：
To develop an evaluation method for accurately assessing the structural performance of existing reinforced concrete structure, it is necessary to discuss the corrosion characterization of reinforcing bar, which has a large effect on the structural performance. In this paper, the variations in corrosion characteristics and mechanical properties of corroded reinforcing bars in reinforced concrete slabs and beams of open-type wharves were discussed. From the tests and analyses, unevenness of cross-sectional loss had a great influence on the mechanical properties of corroded steel bar because of the lopsided action of tensile stress.
