Abstract:
Past studies have reported reduced strength and ductility of corroded reinforcing bars evaluated using standard tensile tests. Based on the research presented in this article, when damaged bars are bonded to concrete, the major factor affecting flexural behavior of a reinforced concrete member is the average section loss of the bars. Bond between the concrete and the bars loads multiple bars to similar strain levels and allows redistribution to occur, thereby minimizing the influence of corrosion pitting.
