Abstract:Recently, the use of steel fibers has been increased in flexural members and columns of concrete structures subjected to cyclic loadings, such as bridge decks, highway roads, airport runways, and buildings. However, few experimental tests have been carried out under fatigue loading. In the present study, reinforced concrete beams with fiber volume fractions of 1 and 2 percent, with and without stirrups, were investigated. Fatigue tests found that the failure of the beam is usually due to breaking of fibers rather than fiber pullout. A comparison of experiments and numerical analysis using a nonlinear finite element method program (ADINA) is also presented.
