In order to study the mechanical properties of concrete-filled glass fiber reinforced polymer (GFRP) tubular short columns under single axial compression and repeated axial compression under different reinforcement modes, twelve specimens of concrete-filled GFRP tubular short columns were produced. And the concrete-filled GFRP tubular short columns were reinforced by carbon fiber reinforced polymer (CFRP) cloth in different ways. Based on the test results, the failure mode, load carrying capacity of columns, deformation capacity, reinforcement effect, stress-strain curve, relationship between plastic residual strain and unloading strain and limit state of specimens were analyzed. It shows that the ultimate strength of the specimens in three reinforcement modes is improved greatly; there is a linear relationship between the plastic residual strain and the unloading strain of the specimen before and after reinforcement, and the slope of the straight line increases with the strengthening of the restraint. Modifying the FRP-confined concrete loading and unloading model proposed by Lam and Teng. Predicting the unloading path of CFRP-reinforced GFRP pipe concrete composite short columns by the modified model under repeated axial compression. After comparing, it shows that the test results agree well with the modified model.
