Highlights Effects of confinement on the bond strength of corroded RC beams are investigated. An increase in stirrups increase the bond strength of corroded RC beams. Ductility and energy dissipation potential of beams are affected by stirrups.
Abstract This study has addressed effects of stirrups-caused confinement on the concrete-bar bond strength of lap-spliced RC beams which have been corroded. Twenty of such beams with different stirrup spacing in the spliced region were subjected to corrosion, and the percentages of corrosion of the lap-spliced tensile bars were considered as the variable of this study; these beams were tested under four-point bending test. Tests results have shown that the increased stirrups in the spliced region increased the bond strength, ductility, and energy dissipation potential. Stirrups were more effective in high corrosion; at 25% corrosion.
