| 摘 要： | 在实际工程中，圆钢管混凝土柱两端有可能承受偏心距不同的压力。利用有限元软件ABAQUS建模对圆钢管混凝土不等偏压柱的荷载一变形关系全过程进行了计算，计算结果与大量试验结果符合良好，这验证了该方法模拟圆钢管混凝土不等偏压柱受力过程的正确性。最后，列出了采用等效长度法和模型柱法对上述试件承栽力的计算结果，通过与试验结果的对比，3种方法均总体偏于安全，其中有限元计算结果吻合最好。

| Abstract: | In practical projects, circular concrete-filled steel tube columns are subjected to double curvature bending possibly. In this paper, load-deformation relationship of circular concrete-filled steel tube columns subjected to double curvature bending are analyzed by finite element software ABAQUS. The calculated results are in good agreement with the experimental results, which verifies the correctness of finite element calculation. Finally, the results of equivalent length method and fiber model method for the calculation of bearing capacity of the above-mentioned specimen are listed. The results of three methods are genemUy conservative and finite dement calculation agrees with experimental results. |
