WebSteel-fibre-reinforced concrete. Design of steel-fibre-reinforced concrete is not covered by design standards such as BS 8110 (now withdrawn) or Eurocode 2, which assume the use of bar reinforcement. Various design approaches are currently adopted. The first may be described as Design on the basis of material properties. In this approach ... WebDetails Design values of concrete material properties according to EN1992-1-1. Unit weight γ The unit weight of concrete γ is speci ed in EN1991-1-1 Annex A. For plain unreinforced concrete γ = 24 kN/m3. For concrete with normal percentage of reinforcement or prestressing steel γ = 25 kN/m3. Characteristic compressive strength fck
