Form6Dot27ShearForceInWall(tau_t_i_t_ef_i: N_MM, z_i: MM)

Bases: Formula

Class representing formula 6.27 for the calculation of the shear force in a wall, [\(V_{Ed,i}\)].

[\(V_{Ed,i}\)] Shear force in a wall [\(N\)].

EN 1992-1-1:2004 art.6.3.2(1) - Formula (6.27)

Parameters:

  • tau_t_i_t_ef_i (N_MM) –

    [\(\tau_{t,i} t_{ef,i}\)] Shear stress in a wall of a section subject to a pure torsional moment multiplied with the effective thickness [\(N/mm\)].

  • z_i (MM) –

    [\(z_{i}\)] is the side length of wall i defined by the distance between the intersection points with the adjacent walls [\(mm\)].
