The Young's modulus for concrete is calculated by default according to EN1992 by:
E'c = E'cm / (1 + φ)
Taken into account restrictions from NVN 6724:2001:
- Value for E'cm is limited in the calculation of E'c to 32300 MPa (common to C28/35)
- (1 + φ) ≤ 2.0
The default value (colored blue) could be redefined manually (colored black).
