| Abstract: | The experimental study on fatigtie fracture properties of steel fiber reinforced concrete under equal and vari able amplitude cyclic loading is introduced in this paper. The pa rameters of the Study were; fiber type, fiber volume and the stress - to0strength ratio.The main emphasis was place on the fatigue life, energy absorption characteristics and damage accu mulation. Fiber up to 2. 0 percent have considerable beneficial effect on fatigue behavior of concrete. The damage accumulation law is introduced. |
