Classes:

codes.eurocode.en_1993_1_1_2005.chapter_6_ultimate_limit_state.formula_6_8.Form6Dot8NetDesignTensionResistance 

Form6Dot8NetDesignTensionResistance(
    a_net: MM2, f_y: MPA, gamma_m0: DIMENSIONLESS
)

Bases: Formula

Class representing formula 6.8 for the calculation of [\(N_{net,Rd}\)].

[\(N_{net,Rd}\)] Calculation of the design tension resistance [\(N\)].

EN 1993-1-1:2005 art.6.2.3(4) - Formula (6.8)

Parameters:

  • a_net (MM2) –

    [\(A_{net}\)] Net area at holes for fasteners [\(mm^2\)].

  • f_y (MPA) –

    [\(f_y\)] Yield strength of the material [\(MPa\)].

  • gamma_m0 (DIMENSIONLESS) –

    [\(\gamma_{M0}\)] Partial safety factor for resistance of cross-sections whatever the class is.
