英文摘要	To study the dynamic performance of concrete-filled steel tubular (CFST) piles under impact loads, the strain and displacement responses of the members were studied by oblique impact tests. Then the experimental process was simulated, and the simulation results are in good agreement with the test. Finally, parameter analysis based on numerical simulation is conducted to study the influence of the section stiffness and impact energy on the dynamic response of the members, as well as the energy absorption of the members are studied, and the response mode of the members is summarized. The results show that the response modes of CFST piles can be summarized as slight bruise at the impact point, dented damage at the impact point, bending deformation of the member, and failure of restrained end of the member. The displacement and energy absorption rate are sensitive to the variation of section stiffness, impact energy, impact height and angle. The impact force is sensitive to the change of section stiffness, impact energy and height, but not sensitive to the change of impact angle. The energy absorption rates are more than 50%, and the maximum energy dissipation rate reaches 91.3%.
