| Abstract: | The concrete filled double skin steel tubes column under axial loads is studied based on the unified strength theory in the paper.The strength difference effect(SD Effect)in tension and compression and the intermediate principal stress effect on the ultimate strength for the concrete filled double skin steel tubes column have been investigated.The ultimate load calculation formula for the concrete filled double skin steel tubular column is derived in this paper.Compared with the solution obtained in this paper and the experimental results,the good agreement can be found.Based on the analysis result it can be concluded that the concrete filled double skin steel tubular column has the same merit with the concrete filled steel tube and this solution has an important practical value for engineering application. |
