This paper presents an experimental study on 25 FRC beams. It is proved that main variable such as the steel fiber and the high-strength concrete have great effects on the first cracking strength, the ultimate strength, the ductility of the FRC beams. The formula for calculating normal section strength of flexural HFRC beams is presented.
Keywords: fiber reinforced concrete; high-strength concrete; beams; flexural; normal section strength
