Structural engineers have to address the climate change challenge by designing sustainable and resilient structures. At this juncture, Electric Arc Furnace Slags (EAFS), a steel-industry waste, are used in replacement of natural aggregates enhance concrete properties. Moreover, steel synthetic fibers added improve postcracking behavior while traditional bar reinforcement enhances tensile performance. This makes EAFS substantially ductile compared normal concrete, which contributes higher structural resiliency, hence minimizes functionality disruptions. However use fiber -reinforced structures is still limited due uncertainties introduced fibers. justify development advanced modeling techniques (ie. Finite element Analysis, FEA), can be predict at stage. work build up from extensive coauthors testing and, more recently, developed FEA fiber-reinforced concrete. In paper study elements made with The presented validated through full-scale experiments (four-point flexural test), shows that appropriate. numerical model enables phenomena difficult or in-situ such as cracking. It worth noting addition reduced crack mouth opening displacement 29.3% depth cracks 12.7%
