Formula 2.1a from NEN 9997-1+C2:2017: Chapter 2: Basis of geotechnical design.

Classes:

  • Form2Dot1aDesignValueLoad –

    Class representing formula 2.1a for the calculation of the design value [\(F_{d}\)] of actions.

codes.eurocode.nen_9997_1_c2_2017.chapter_2_basic_of_geotechnical_design.formula_2_1_a.Form2Dot1aDesignValueLoad 

Form2Dot1aDesignValueLoad(gamma_f: DIMENSIONLESS, f_rep: DIMENSIONLESS)

Bases: Formula

Class representing formula 2.1a for the calculation of the design value [\(F_{d}\)] of actions.

[\(F_{d}\)] Design value of actions.

NEN 9997-1+C2:2017 art.2.4.6.1(2) - (Formula 2.1a)

Parameters:

  • gamma_f (DIMENSIONLESS) –

    [\(\gamma_{F}\)] partial factor for actions for persistent and transient situations defined in annex A [\(-\)].

  • f_rep (DIMENSIONLESS) –

    [\(F_{rep}\)] Representative value of actions.

    Use your own implementation for this value or use :class:Form2Dot1bRepresentativeValue.
