Presented for the first time are the results of an experimental investigation comparing the behaviour of reinforced concrete (RC) columns strengthened with transverse fibre reinforced polymer (FRP) wrapping under impact loads with equivalent unwrapped columns. Eleven tests were conducted with the impact velocity and point of load application varied. It was shown that the peak displacements of columns strengthened with FRP were up to 39% lower than those of specimens not wrapped with FRP for comparable impacts. Through a plasticity theory based model it was shown that the improved behaviour could be predicted by allowing concrete to reach a much higher failure strain, as a result of the confinement provided by the FRP wraps.
