Form3Dot3AxialTensileStrengthFromTensileSplittingStrength(f_ct_sp: MPA)

Bases: Formula

Class representing formula 3.3 for the approximated axial tensile strength, [\(f_{ct}\)], determined by tensile splitting strength.

[\(f_{ct}\)] The approximated axial tensile strength when tensile strength is determined as coefficient which is dependent of the age of concrete [\(MPa\)].

EN 1992-1-1:2004 art.3.1.2(8) - Formula (3.3)

Parameters:

  • f_ct_sp (MPA) –

    [\(f_{ct,sp}\)] Tensile strength determined by tensile splitting strength [\(MPa\)].

Returns:

  • None –
