Abstract
In order to study the axial compression performance of GFRP tube composite columns filled with concrete and better applied to engineering, the influence of different winding angle of GFRP tube, thickness of GFRP tube, concrete strength and the containing rate of steel are simulated by using finite element analysis software ABAQUS when the column under the axial compression ,The results show that: the numerical results are in good agreement with the experimental results; reduced GFRP tube winding angle, increasing the GFRP tube thickness, improve the core concrete strength and an increase in steel containing rate could increase the bearing capacity of columns.
