Concrete Modulus of Elasticity

  • The modulus of elasticity for concrete is calculated per 3.1.2(a).
  • The value of fcm in the calculation is taken from Table 3.1.2. Linear interpolation is used between the table values.
  • The tabulated fcmi value for f’c = 100 Mpa is used when f’c exceeds 100 MPa. It is recommended to use specified Ec values when f’c exceeds that value.
  • This calculation must be selected in the Materials window to be used.
