Calculated Value for Stress-Strain Diagram

Calculated Value f<sup>f</sup><sub>ctR,i</sub> for Stress-Strain Diagram

{f^{f}}_{ctR, i} = {κ^{f}}_{G} \cdot {κ^{f}}_{F} \cdot {f^{f}}_{ct 0, i}

κ^f_G	Factor for considering the influence of the structural component size on the variation coefficient = 1.0 + A^f_ct ⋅ 0.5 < 1.70
A_ct	Cross-section area of the cracked areas in m² belonging to the respective equilibrium state and subjected to tensile stress
κ^f_F	Factor for considering the fiber orientation = 0.5. For planar, horizontally produced laminar structural components (b < 5), an assumption of κ^f_F = 1.0 for bending and tensile stress is allowed.
