Fibre reinforced plastic-steel composite tube restrained reinforcement high-strength concrete column

The invention discloses a fiber reinforced plastic-steel composite tube restrained reinforcement high-strength concrete column, comprising longitudinal bars, stirrups, high-strength concrete and a fiber reinforced plastic-steel composite tube, wherein circular stirrups are sheathed on the longitudinal bars along the height direction, the fiber reinforced plastic-steel composite tube is sheathed outside the stirrups along the height direction of the column, the fiber reinforced plastic-steel composite tube is compounded by a steel tube which is taken as an inner wall and a fiber reinforced plastic tube which is taken as an outer wall, solid high-strength concrete is cast in the fiber reinforced plastic-steel composited tube, and the fiber reinforced plastic-steel composite tube is disconnected at the two terminals of the column. The column in the invention is improved in the earthquake resistance of the reinforcement high-strength concrete column and the durability of the steel tube restrained reinforcement hi
