Table 4.2 from NEN-EN 1992-1-1:2005+A1:2015+NB:2016+A1:2020: Chapter 4 - Durability and cover to reinforcement.

Classes:

codes.eurocode.national_annex.nl.nen_en_1992_1_1_a1_2020.chapter_4_durability_and_cover.table_4_2.Table4Dot2MinimumCoverWithRegardToBond 

Table4Dot2MinimumCoverWithRegardToBond(
    diameter: MM, nominal_max_aggregate_size_greater_than_32_mm: bool
)

Bases: Formula

Class representing the table 4.2 for the calculation of the minimum cover [\(c_{min,b}\)] [\(mm\)] requirements with regard to bond.

[\(c_{min,b}\)] Calculates the minimum concrete cover with regard to bond [\(mm\)].

NEN-EN 1992-1-1:2005+A1:2015+NB:2016+A1:2020 art.4.4.1.2 (3) - Table (4.2)

Parameters:

  • diameter (MM) –

    Diameter of the reinforcement [\(mm\)]. In case of bundled bars, the equivalent diameter [\(Ø_{n}\)] as defined in par. 8.9.1 should be used. Use your own implementation of this value or use the :class:Form8Dot14EquivalentDiameterBundledBars class.

  • nominal_max_aggregate_size_greater_than_32_mm (bool) –

    Is the nominal maximum aggregate size greater than 32 [\(mm\)]?
