Abstract:
The structural behavior of steel fiber reinforce concrete beams in shear is studied. A comprehensive experimental program has been set up and several series of reinforced concrete beams with steel fibers have been tested. The test variables include the volume contents of steel fibers and stirrups. The fiber contents varies from 0% to 2% by volume. It is seen form these tests that the cracking and ultimate shear strengths increase as fiber content increase. The present study indicates that fiber reinforcement can reduce the amount of shear stirrups may accomplish strength requirements s well as ductility requirements. A theoretical approach is proposed to predict the shear strength of reinforced concrete beams containing steel fibers and good correlations obtained with test data. The present study allows more efficient structural application of steel fibers for shear reinforcement in reinforced concrete structures.
