UNDERGROUND SOLUTIONS, THE BEKAERT SEMINAR on steel-fibre reinforcement, was held at the Institution of Civil Engineers in London on 29 October 2019. Kicking-off the proceedings was a presentation on the design of steel fibre-reinforced concrete (SFRC) structures given by Remy Roland, Bekaert South Europe technical manager.Explaining that steel fibres transfer forces across cracks in concrete, Mr Roland highlighted their material characteristics, design values, section design and structural SFRC design. He said that in terms of parameters influencing mechanical performance of 3D, 4D and 5D with the same lengths and diameters, pull-out tests for Dramix show that for 3D and 4D, ductility comes from a controlled sliding of the fibre within the concrete matrix. Structural design can be achieved with steel fibre only and a combination of steel fibres plus rebar and mesh.
