In order to study the effects of wall thickness and impact times on the splitting tensile properties of FRP pipe concrete steel pipe, the dynamic impact test of FRP pipe concrete steel pipe is carried out by using the separated Hopkinson compression bar system with a diameter of 74mm. By changing the wall thickness and impact times, the variation laws of FRP concrete dynamic characteristics under different conditions are analyzed. The test results show that the increase of FRP pipe thickness greatly improves the load resistance of the specimen, the increase of FRP pipe thickness greatly improves the toughness and fatigue resistance of the specimen, and the energy absorption capacity of FRP pipe material is better than that of concrete; In terms of failure mode, the increase of FRP pipe thickness significantly enhances the protection ability of the specimen.
