Data Source and Methodology
All calculations are rigorously based on the formulas and data provided by Eurocode 2 (EN 1992-1-1:2004). For further details, refer to the official document: Eurocode 2.
All calculations are based strictly on the formulas and data provided by this source.
The Formula Explained
Crack Width (wk) = αe × (fct,eff / ρp,eff) × (heff / c)
Glossary of Terms
- Reinforcement Ratio (%): Percentage of reinforcement in the concrete section.
- Tensile Stress (N/mm²): The stress experienced by the concrete under tension.
- Crack Width: The estimated width of cracks in the concrete.
How It Works: A Step-by-Step Example
To estimate the crack width, enter the reinforcement ratio and tensile stress values. The calculator will apply the Eurocode 2 formula to provide an estimated crack width. For example, with a reinforcement ratio of 1% and a tensile stress of 2 N/mm², the estimated crack width is calculated as follows...
