The paper deals with an experimental study on the fatigue behavior of plain and Steel Fiber Reinforced Concrete (SFRC). The research was carried out by studying the fatigue behavior of cracked concrete by means of three point bending tests. The effects of two different fiber contents and three different load levels were investigated and the fatigue performances of plain and SFRCs are compared. Despite the variable information regarding the fatigue behavior of concrete reported in the literature, this research study highlights that the inclusion of fibers can improve the fatigue performance of SFRC for high tensile stresses, guaranteeing a longer structural life.
