This work describes the new compressive stress-strain model for non-linear analysis of steel-fibre reinforced concrete (SFRC) in the new Eurocode 2, Annex L (version 2022–05), developed within task group CEN TC250/SC2/WG1/TG2—Fibre reinforced concrete. The new model takes advantage of the substantial deformation capability increase given by the fibres’ reinforcement to any base concrete. The model is grounded on a multivariate analysis that correlates an extensive database of 197 well-documented SFRC compressive tests and 484 flexural tests. The model and the results of the correlations with the database also allow us to link the flexural performance classes in Annex L and the SFRC compressive strength, which permits a complete classification of any material. Finally, we give an example of the application of the model that shows the enhancement in ductility and strength of a composite steel-SFRC beam section.
