Abstract: The present disclosure discloses a Fiber Reinforced Polymer/Plastic (FRP) composite spiral stirrup confined concrete column and a compression design method. The FRP composite spiral stirrup includes an internal FRP spiral stirrup and an external FRP square stirrup. In the form of the FRP composite spiral stirrup, effective transverse stress transfer is established by effectively binding stirrups, which can give full play to the mechanical properties of the FRP bars, provide “dual confinement” for core concrete, and greatly improve the peak stress of the core concrete. Confining mechanisms of the FRP composite spiral stirrup to the concrete in different areas are analyzed, a confinement model and a bearing capacity calculation method for the FRP composite spiral stirrup confined concrete column are proposed, and a design method for the FRP composite spiral stirrup confined concrete column is proposed after an accurate calculation method for the bearing capacity is obtained.
