Influence of localized corrosion of steel bars on structural performance of reinforced concrete beams

Figure 1 shows the geometry and steel bar arrangements of tested RC beams. Five RC beams with identical dimensions were prepared. All the beams were designed in such a way that flexural failure precedes the occurrence of shear failure. The diameters of deformed steel bars were 16 mm for longitudinal bar and 6 mm for stirrup. Table 1 presents mixture proportion of concrete. Mechanical properties of concrete and steel bars are summarized in Table 2.
