| Abstract: | Results of an experimental investigation of the behavior of steel fiber reinforced concrete under cyclic compressive loading are presented. The parameters of fiber type, fiber volume and the tress-strength ratio are all studied. The main emphasis is placed on the fatigue life, energy absorption and damage accumulation. Fibers up to 2 percent have considerable beneficial effect on the fatigue behavior of concrete. Fibers dissipate much more additional energy at lower stress levels than at higher stress levels. |
