Resumo

The use of steel fibers as addition improves several mechanical properties of concrete, whose tensile strength and resilience are of great interest for designs of structures subjected to impact loads, such as military facilities, nuclear power plants, bridges and overpasses. However, there are few studies that assessed the effects of adding steel fiber on reinforcements of reinforced concrete. To assess these effects, four concrete beams under impact loads were tested, with reinforcements and different amounts of steel fibers being monitored. The results showed a better performance of beams with fibers, presenting lower strains on reinforcements and cracking.
