摘要：

The results of an experimental study for assessing the degradation of the fatigue properties of reinforcing steel bars grade S400 caused by exposure to laboratory salt spray corrosion environment are presented. For this purpose, low cycle fatigue (LCF) tests were carried out. Furthermore, the effect of ribs on the fatigue strength was recorded. Results are indicative of the catalytic impact of corrosion on LCF behavior. Since two important degradation factors such as corrosion and LCF are functions of time, it appears that the reliability of steel S400 is also time dependant. Additionally, the presence of ribs on material's surface affects significantly the fatigue behavior by reducing energy dissipation and duration of test.
