Anti-knock energy dissipation structure of circular hollow concrete-filled steel tube composite column

The utility model discloses an anti-knock energy dissipation structure of a circular hollow concrete-filled steel tube composite column. The anti-knock energy dissipation structure comprises the hollow concrete-filled steel tube composite column, carbon fiber cloth and a foamed aluminum material, the hollow steel tube concrete composite column is located on the inner layer of the anti-explosion energy-dissipation concrete composite column, the carbon fiber cloth is adhered to the concrete composite column through resin adhesive, the foamed aluminum material is made into a honeycomb shape and is adhered to the carbon fiber cloth, and the carbon fiber cloth material layer is arranged between the composite column and the foamed aluminum material. Loss of bearing capacity of the hollow concrete-filled steel tube composite column with the circular section under the action of blast load is reduced; local collapse or even overall collapse of a building structure caused by failure of the concrete composite column is
