In order to improve the carrying capacity of the pultruded glass fiber reinforced plastics (GFRP) tube, five specimens were produced with carbon fiber reinforced plastics (CFRP) cloth with different restraint methods and axial compression tests were conducted. The damage mode of this restrained combined column was obtained. Through the analysis of the CFRP restraint effect and the load-bearing performance of this column, the load-bearing capacity calculation model was established. The results show that the squeezed GFRP and the concrete are crushed when the test piece is damaged, some specimens were accompanied by a band tear of CFRP. Disruption morphology increases with the effect of lateral constraint, development from typical cracking fracture to brittle crushing destruction and shear destruction. The bearing capacity of test parts gradually increases with the decrease of CFRP distance, test piece bearing capacity can be greatly improved at a CFRP distance of <100mm, Maximum increase of 1.5 times, when the CFRP spacing is ≥100mm, the improvement of the carrying capacity is not obvious. The change of CFRP spacing and layout mode improved the deformation performance of the test parts significantly, the ductility of the components can be significantly improved. Based on the theory of restrained concrete, the calculation model of specimen bearing capacity established by considering different CFRP spacing and the effect of GFRP bearing action has a high accuracy of calculation results.
