3 Materials

3.1 Concrete

3.1.2 Strength

procedure EN2_11__3_1_2__StrengthCharacteristics(fck: Double; var fckcube, fcm, fctm, fctk5, fctk95: Double); 
stdcall; external [DllName];

Returns strength characteristics of concrete in accordance with 3.1.2 EN 1992-1-1 (Table 3.1).

Parameters:

  • fck - characteristic (5%) cylinder strength [MPa];

Variables:

  • fckcube - characteristic (5%) cube strength [MPa];
  • fcm - mean compressive strength at 28 days [MPa];
  • fctm - mean value of axial tensile strength [MPa];
  • fctk5 - characteristic (5%) axial tensile strength [MPa];
  • fctk95 - characteristic (95%) axial tensile strength [MPa].

3.1.3 Elastic deformation

procedure EN2_11__3_1_3__DeformationCharacteristics(fck: Double; var Ecm, ec1, ecu1, ec2, ecu2, n, 
ec3, ecu3: Double); stdcall; external [DllName];

Returns demormation characteristics of concrete in accordance with 3.1.2 EN 1992-1-1 (Table 3.1).

Parameters:

  • fck - characteristic (5%) cylinder strength [MPa];

Variables:

  • Ecm - secant modulus of elasticity of concrete [GPa];
  • ec1 - compressive strain in the concrete at the peak stress fc;
  • ecu1 - ultimate compressive strain in the concrete;
  • ec2 - strain at reaching the maximum strength;
  • ecu2 - ultimate strain;
  • n - factor;
  • ec3 - simplified bi-linear analog of strain ec2;
  • ecu3 - simplified bi-linear analog of strain ecu2.
