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. Web14 nov. 2024 · So, the concrete area below the neutral axis is neglected and the effective area or the equivalent area of the section in terms of concrete is shown in Fig. 2.3(b). The equivalent area is equal to the area of concrete in the compression zone and an additional concrete area mA st of conrete corresponding to steel area, A st. Strain Diagram
