Formula 4.1 from EN 1992-1-1:2004: Chapter 4 - Durability and cover to reinforcement.

Classes:

codes.eurocode.en_1992_1_1_2004.chapter_4_durability_and_cover.formula_4_1.Form4Dot1NominalConcreteCover 

Form4Dot1NominalConcreteCover(c_min: MM, delta_c_dev: MM)

Bases: Formula

Class representing the formula 4.1 for the calculation of the nominal concrete cover [\(c_{nom}\)] [\(mm\)].

[\(c_{nom}\)] Calculates the nominal concrete cover [\(mm\)].

Please be advised that this formula does not take various considerations in art.4.4.1.2 and 4.4.1.3 into account. For a more detailed calculation, please refer to the NominalConcreteCover class.

EN 1992-1-1:2004 art.4.4.1.1 (2) - Formula (4.1)

Parameters:

  • c_min (MM) –

    [\(c_{min}\)] Minimum concrete cover based on art. 4.4.1.2 [\(mm\)].

  • delta_c_dev (MM) –

    [\(\Delta c_{dev}\)] Construction tolerance based on art. 4.4.1.3 [\(mm\)].
