Fatigue constitutive laws of concrete and S – N curves of steel bars have been investigated widely. This study aims to explore the failure problems of reinforced concrete (RC) beams subjected to cyclic loads and corrosive actions. The live loads obtained from Chinese technical standards and practical surveys were adopted in experiments and numerical calculations. A series of tests were conducted to study the fatigue performance of normal and corroded RC beams. A numerical method was proposed to calculate the fatigue damage of RC beams under corrosive actions and cyclic loads. The performance of RC beams with increasing fatigue cycles were analyzed using MATLAB software in which the global stiffness degradation was introduced to represent the property evolutions of corroded steel bars and concrete.
