According to the test method recommended by RILEM,three-point bending tests on notched beams of steel-fiber reinforced high-performance concrete(SFHPC) were carried out.The experimental results show that both steel fiber type and steel fiber content play important roles in the flexural toughness and fracture energy of high-performance concrete(HPC).The energy absorption capacity and fracture energy of SFHPC increase obviously with the increase of steel fiber content.Compared to the marked steel fiber with lower strength,the hooked steel fiber with higher strength has better effects on the flexural toughness and fracture energy of HPC.The mechanical and failure characteristics of SFHPC beams in bending test can be described well by using fracture energy and flexural toughness indices together.
