Abstract
Practical application of FRP reinforcement to reinforced concrete structures is at present attracting technical attention. The object of this study is to make an analytical examination on how FRP rods influence the impact resistance of concrete slabs. The concrete slabs are modeled using the layered finite element method and the Newmark-β method is employed to solve the equations of motion during discrete time intervals. As a result, FRP rods are efficient as reinforcement, and the degree of contribution to impact resistance can be evaluated quantitatively by the following indexes ; impact force at failure, volume displaced, impact failure mode, etc.
