Abstract: JSCE-331 sub-committee in Concrete Committee of Japan Society of Civil Engineers conducted a benchmark test on the load-carrying behaviour of RC beam deteriorated by the corrosion of the reinforcement according to the common experimental procedure, including the design of the specimen, the simulating technique of the corrosion, the measuring method of the corrosion and the loading procedure. In this paper, the load-carrying capacity of the corroded RC beam was discussed from the viewpoint of the scatter in the common test results.
The results of the common test indicated that the large ratio of the corrosion weight loss was highly likely to induce the failure due to the fracture of the longitudinal reinforcement, because the longitudinal scatter in the cross-sectional area of corroded reinforcement increases as the corrosion loss increases. Consequently, the RC beams with the large ratio of the corrosion weight loss show the significant reduction and the large scatter in the flexural capacity.
