Mu/4d area of steel
WebThe unit weight of steel γ is specified between 77.0 kN/m 3 and 78.5 kN/m 3 . In this calculation the density of reinforcement steel is assumed equal to ρ = 7850 kg/m. For n isolated reinforcement bars the total weight is: wtot = n ⋅ ρ ⋅ As. For distributed reinforcement bars at spacing s the total weight is: wtot / s = ρ ⋅ As / s.
