| During this research, the buckling behavior of elliptical CDFST columns is investigated numerically in Abaqus Software using transverse reinforcements in the outer tube of the column. For this purpose, an elliptical CFDST column is simulated in Abaqus Software and subjected to compressive loading. The transverse reinforcements are validated and placed in the outer tube of the elliptical CFDST column, and parameters such as thickness, reinforcement dimensions, and distance between them vary within the range of 4, 6, 8 mm; 2, 4, 6 cm, and 2, 4 and 6 cm, respectively and a total of 27 models will be analyzed during the research. The results obtained from this study are in good agreement with the results of previous studies and showed that the finite element method can provide accurate behavior of these columns. The results of this study showed a 15 to 40% increase in load-bearing capacity with the highest compressive strength in elliptical CFDST columns using transverse reinforcements. Also, the effect of increasing the thickness and dimensions on load bearing enhances by 20% and 15%, respectively while the effect of increasing the distance between transverse reinforcements reduces the bearing capacity by 10%. The maximum axial strength was observed in CFDST columns with transverse reinforcements. | ||
