Abstract：This study proposes the use of honeycomb sandwich panels to protect RC walls,forming a honeycomb sandwich panel composite RC wall(HSP-RC wall).The dynamic response of standard RC walls and HSP-RC walls with different honeycomb parameters under high-energy impact was studied through pendulum impact experiments,and their impact resistance performance was evaluated.The deformation differences of different HSP-RC walls were compared,and the influence of honeycomb structural parameters on the protection effect was analyzed.The research results indicate that honeycomb sandwich panels provide effective impact protection for RC walls through energy absorption,and their protection effect is closely related to the parameters of the hon-eycomb core layer.
