In order to establish a numerical analysis method for appropriately evaluating the impact behavior of the RC beams strengthened in flexure with FRP sheet under impact loading, 3D elasto-plastic impact response analyses of the RC beam were conducted by varying three different constitutive models for concrete: KCC; CSCM; and proposed model. The applicability of each constitutive model was investigated to compare with the experimental results. Results obtained from this study were as follows: 1) in the case of the unstrengthened RC beams, the dynamic impact behavior of the beam can be properly predicted irrespective of the models; and 2) in the case of the strengthened RC beams, the dynamic response behavior can be appropriately simulated by applying the proposed model.
