Form6Dot17CheckShearForce(v_ed: N, v_c_rd: N)

Bases: Formula

Class representing formula 6.17 for checking the design value of the shear force.

Check the design value of the shear force at each cross section.

EN 1993-1-1:2005 art.6.2.6(1) - Formula (6.17)

Parameters:

  • v_ed (N) –

    [\(V_{Ed}\)] Design value of the shear force [\(N\)].

  • v_c_rd (N) –

    [\(V_{c,Rd}\)] Design shear resistance [\(N\)].
