Formula 5.11N from EN 1992-1-1:2004: Chapter 5 Structural Analysis.

Classes:

codes.eurocode.en_1992_1_1_2004.chapter_5_structural_analysis.formula_5_11n.Form5Dot11nShearSlendernessCorrectionFactor 

Form5Dot11nShearSlendernessCorrectionFactor(lambda_factor: DIMENSIONLESS)

Bases: Formula

Class representing formula 5.11N for the calculation of the shear slenderness correction factor [\(k_{λ}\)].

[\(k_{λ}\)] Shear slenderness correction factor.

EN 1992-1-1:2004 art.5.6.3(4) - Formula (5.11N)

Parameters:

  • lambda_factor (DIMENSIONLESS) –

    [\(λ\)] ratio of the distance between point of zero and maximum moment after redistribution and effective depth, d [\(-\)]

    Use your own implementation for this value or use :class:Form5Dot12nRatioDistancePointZeroAndMaxMoment.
