This study looked at a new shear strengthening approach for impact-loaded reinforced concrete (RC) slabs. This analysis took into account a real-scale RC slab with dimensions of 660 cm × 300 cm × 32 cm. The slab was subjected to an impact of 605 kg mass dropped from 20 m height. Then, the slab was repaired and strengthened by a new configuration of shear reinforcement called “swimmers”. Several outputs were considered in this study like: impact force, acceleration, displacement and damage extent. Results showed that swimmers’ system helped in enhancing shear load capacity of the RC slab. In addition, it helped in changing the damage pattern of the slab from shear to flexure. The outputs of this study helped in providing several recommendations for future research.
