With the development of computer science, the finite element method has been used widely. The paper used the ABAQUS finite element analysis software to carry out the finite element analysis on the middle long columns of high-strength concrete filled square steel tube with inner CFRP circular tube under compressive load. The results of finite element analysis were obtained, which agreed well with theoretical data. This conclusion proved the correctness and feasibility of finite element model.

In this paper, using ABAQUS, 16 high-strength concrete filled high-strength square steel tube middle-long columns’ axial compression process were simulated. The load-deflection relationships were obtained and the new combination in improving the bearing capacity and plastic deformation has a great advantage. Realization of length variation slenderness ratio by changing the length of column, this paper also study the influence of slenderness ratio, the main parameters of the high-strength concrete filled high-strength square steel tube middle-long column. It is found that both bearing capacity and the plastic capacity are associated with slenderness ratio.
