The steel tube wall under the lower stiffening ring appeared residual strain; the bearing capacity of the specimen reached its peak during the sixth loading stage; in the sixth loading stage, the peak point of the hysteresis curve fell rapidly after the ultimate load point, the displacement on the top of the column is larger and the energy dissipation capacity of the specimen increased in a short term, but the material strength also degenerated significantly.
