Table 4.5N 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.table_4_5n.Table4Dot5nMinimumCoverDurabilityPrestressingSteel 

Table4Dot5nMinimumCoverDurabilityPrestressingSteel(
    exposure_classes: Table4Dot1ExposureClasses,
    structural_class: ConcreteStructuralClassBase,
)

Bases: Formula

Class representing the table 4.5N for the calculation of the minimum cover [\(c_{min,dur}\)] [\(mm\)] requirements with regard to durability for prestressing steel.

[\(c_{min,dur}\)] Calculates the minimum concrete cover with regard to durability [\(mm\)] for prestressing steel.

EN 1992-1-1:2004 art.4.4.1.2 (5) - Table (4.5N)

Parameters:

  • exposure_classes (Table4Dot1ExposureClasses) –

    The exposure classes of the concrete. Use the [\(Table4Dot1ExposureClasses\)] class. [\(-\)]

  • structural_class (ConcreteStructuralClassBase) –

    The structural class of the concrete. Use the [\(Table4Dot3ConcreteStructuralClass\)] class. [\(-\)]
