The compressive strength of AFRP-wrapped concrete column under high strain rate was experimentally studied utilizing an 100 mm diameter SHPB apparatus． The results indicate that the compressive strength was enhanced under high strain rate and presented clear strain rate dependence; when the strain rate was kept similar，the dynamic compressive strength first increased and then decreased，in which 2-ply AFRP-wrapped concrete exhibited the best enhancement property． Besides，a new ultimate strength model was obtained by modifying the Bethet strength model considering strain rate effect．
