Form9Dot14SplittingForceColumnOnRock(c: MM, h: MM, n_ed: KN)

Bases: Formula

Class representing the formula 9.14 for the calculation of the splitting force on a column footing on rock.

[\(F_s\)] Splitting force on a column footing on rock [\(kN\)].

EN 1992-1-1:2004 art.9.8.4(2) - Formula (9.14)

Parameters:

  • c (MM) –

    [\(c\)] Width over which [\(N_{Ed}\)] is applied [\(mm\)].

  • h (MM) –

    [\(h\)] Lesser of [\(b\)] and [\(H\)] from figure 9.14 [\(mm\)].

  • n_ed (KN) –

    [\(N_{Ed}\)] Design value of the applied axial force [\(kN\)].
