•A comprehensive review about effects of volume fraction and shape of steel fibers in SFRC under dynamic loading has been conducted in this article.•The obtained results from previous studies have been compared and reached a noticeable outcome for future studies. Among the properties of steel fiber-reinforced concrete (SFRC), the volume fraction and shape of steel fibers play an important role when the concrete is subjected to impact and high-velocity loading. In this study, material responses obtained through impact tests, such as the drop weight test, the split Hopkinson pressure bar test, and the swinging pendulum test, are classified and briefly illustrated. The structural responses of several types of fiber-reinforced concrete with steel fibers are introduced and compared. Given the significance of this topic, an up-to-date review of available literature is provided to enhance our current understanding of the behavior of SFRC with varying volume fractions and shapes of steel fibers under different loading rates. The areas where further research is required are highlighted.
