This study experimentally investigated the influences of bending crack and water-cement ratio (w/c) on the chloride-induced corrosion on main reinforcing bars and stirrups. Special features of this study included crack formation through application of bending load, consideration of main reinforcing bars and stirrups together, and measurements of both macrocell and microcell currents. An indoor examination investigated the corrosion of main reinforcing bars and stirrups on model beams. To clarify the indoor examination results, larger-scale beams exposed to an outdoor environment were investigated. Results showing the influences of bending cracks and w/c on the corrosion rate were reported.
