The dynamic compressive behavior of PET (i.e., Polyethylene Terephthalate) FRP-confined concrete was experimental investigated through a 75-mm-diameter split Hopkinson pressure bar (SHPB) apparatus. Influence of the loading rate ranging from 50s-1 to 250s-1 was examined, and the confinement level was also examined by varying the number of PET FRP layers. Due to the large rupture strain characteristics, PET FRP-confined concrete exhibited excellent performance in resisting impact loading. The specimens maintained the shape and bearing capacity after the first impact with a strain rate value of 200s-1. Repeated impact loading was conducted on the specimens with no rupture of PET FRP jacket after the first impact. The damage evolution of PET FRP-confined concrete was discussed based on the test results of specimens under multiple impact loading.
