Unit System: mm-s-tonne-N-MPa (MPa for pressure/stress, ton/mm³ for density)
1. CEB-FIP. Model Code 2010. Volume 1, Bulletin 65.
2. Eurocode 2. Design of concrete structures - Part 1-1: General rules and rules for buildings (EN 1992-1-1).
This calculator implements the CEB-FIP Model Code 2010 and Eurocode 2 formulations for concrete material properties, providing comprehensive characterization of concrete behavior including stress-strain relationships, biaxial failure envelopes, and statistical strength variations based on production control levels.
