Calculated Value for Stress-Strain Diagram

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

ffctR,i = κfG ⋅ κfF ⋅ ffct0,i

κfG

Factor for considering the influence of the structural component size on the variation coefficient = 1.0 + Afct ⋅ 0.5 < 1.70

Act

Cross-section area of the cracked areas in m² belonging to the respective equilibrium state and subjected to tensile stress

κfF

Factor for considering the fiber orientation = 0.5. For planar, horizontally produced laminar structural components (b < 5), an assumption of κfF = 1.0 for bending and tensile stress is allowed.
