摘要：

The bearing capacity of FRP confined concrete-filled steel tubular (FRP-CFST) columns under axial compression was investigated. This new type of composite column is a concrete-filled steel tube (CFST) confined with fiber-reinforced polymer (FRP) wraps. Totally 11 short column specimens were tested to failure under axial compression. The influences of the type and quantity of FRP, the thickness of steel tube and the concrete strength were studied. It was found that the bearing capacity of short FRP-CFST column was much higher than that of comparable CFST column. Furthermore, the formulas for calculating the bearing capacity of the FRP-CFST columns are proposed. The analytical calculated results agree well with the experimental results.
