Corroded reinforced concrete beams under low-speed and low-cycle fatigue loads

The study performs experimental investigation of the behavior of reinforced concrete (RC) beams with corroded steel reinforcement under low-speed and low-cycle fatigue loads. A total of 14 specimens were tested. The results indicated that the fatigue life cycles decreased by 88.7% when the mass loss increased from 1.56% to 12.56%. The fatigue lives from the present tests were compared with those from other experimental studies and predictions from the CEB-FIP 2010 code and indicated that the fatigue life of concrete estimated by the code is safe for a corroded beam under low-cycle fatigue loading.
