The synergy between SFRC and structural steel in increasing the ductility of composite structures

Our research on the compressive behavior of steel-fiber reinforced concrete (SFRC) led to a constitutive model in Annex L ofthe new Eurocode 2. This recognition piqued the interest of ArcelorMittal, who requested that we explore the implications of increased compression ductility for composite structures, particularly beams with embedded structural steel sections. The findings from this research demonstrate that the compressive ductility of SFRC enables us to fully utilize the tensile capacity of structural steel in composite structures, resulting in unprecedented levels of structural ductility.
