[0028] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings. The present invention provides an FRP-steel reinforcement composite column structure, which is characterized in that the structure comprises four parts: FRP layer 1, concrete 2, reinforcement 3 and steel reinforcement 4; wherein, reinforcement 3 and steel reinforcement 4 The direction is along the axial direction of the composite column structure and is wrapped by concrete 2. The steel frame 4 is located in the center of the section, the reinforcement 3 is evenly arranged around the inner side of the section edge, and the FRP layer 1 surrounds the concrete 2 at the outermost periphery.
[0029] The FRP-steel reinforcement composite column structure described above has a cross-sectional form including a circle and a rectangle with ro...
