In this study, in order to investigate the impact resistance behavior of the flexural reinforced RC beams with AFRP sheet, falling-weight impact tests were conducted taking with/without bonding AFRP sheet and height of a falling weight as variables. From this study, the following results were obtained: (1) impact resistant capacity of the RC beams can be upgraded by reinforcing with AFRP sheet; (2) dynamic load-carrying capacity and maximum input energy for the reinforced RC beams with AFRP sheet are 1.2 times greater than those of not reinforced ones; (3) energy absorption capacity of the RC beams under impact loading are similar irrespective of with/without reinforcing with AFRP sheet; and (4) AFRP sheet bonded onto the tension side surface of RC beam under impact loading tends to be ruptured more easily than the case of static loading.
