| 英文摘要 | Copper material has been widely used in many fields for its good performance in recent years. In order to investigate the overall buckling behavior of TU1 oxygen free copper tubular columns under axial compression, seven full-scale specimens were used for static tests. After measuring the initial bending and loading eccentricity, the study analyzed the buckling failure mode, obtained the overall stability capacity, and constructed a finite element model to simulate the buckling behavior of the seven specimens based on experimental results. The results showed that the overall buckling mode explained the failure modes of all the specimens. In general, the overall buckling strength of the specimens decreased as the slenderness of the columns increased. Besides, the slender the specimen was, the smaller the unrecoverable plastic deformation would be after unloading. In addition, the specimens with the slenderness ratio of 55.9-85.6 were prone to show elastic buckling whereas the specimens with the slenderness ratio of 22.2-44.8 were elasto-plastic buckling. Finally, the finite element model predicted the effects of initial geometric imperfections with precision and the FEA results matched well with the actual experimental results. © 2017, Editorial Board of Journal of Tianjin University(Science and Technology).
