| Outline of Final Research Achievements |
To establish the upgrading method of impact resistant capacity for damaged RC member due to impact loading, falling-weight impact loading tests for flat RC beams strengthened with Fiber Reinforced Polymer (FRP) sheet bonding method were conducted taking with/without cushion layer, with/without FRP sheet bonding, damage level before strengthening as variables. From these experiments, the following results were obtained: 1) impact resistant capacity of the flat RC beams damaged due to impact loading can be upgraded applying an AFRP sheet bonding method; and 2) the maximum deflection of RC beam can be linearly increased corresponding to an increment of input impact energy, irrespective of with/without cushion layer and with/without applying AFRP sheet bonding.
