Abstract

This paper carried out experimental investigation on the behavior of RC beams containing corroded reinforcement. Results from earlier studies demonstrate a consistent association between corrosion level of reinforcements and carrying capacity of beams under static loading test (Dong et al., 2011, Wang et al., 2015). So far, however, there has been little discussion about the simultaneous effect of stirrup spacing and corrosion level of reinforcements on crack patterns at failure and failure mode. Therefore, the main aim of this study is to investigate the behavior of corroded beams with different stirrups spacing in several corrosion levels. Evaluation of the corroded beams was carried out the crack pattern due to loading, residual ultimate strength, and the failure mode of the beams. 20 beams with different distances of stirrup were made and cured under lab conditions. all samples were under accelerated conditions until test time. the behavior of beams under failure load were measured and compared to each other.
