“…The influence of the aspect ratio of the cross-section on the ductility of a CFST stub column was also noticed in [ 20 ], where elliptical cross-sections were analyzed. As a result of the parametric analysis, it was found that the ductility of the columns decreases with the increase in the eccentricity of the ellipse.…”

A total of 5 steel and 21 rectangular composite concrete-filled steel tube (CFST) columns of moderate slenderness were tested to investigate their ductility under axial compression. The importance of the vertical ductility of columns was discussed, and a novel ductility measure was proposed and utilized to examine the ductility of tested specimens. The analyses showed that the ductility of axially compressed CFST columns highly depends on their failure mode. The key feature influencing the ductility is their ability to dissipate the energy of imposed loads. The larger the volume of a material that may permanently deform and consequently dissipate the energy, the greater this ability. In consequence, the ductility of specimens exhibiting local failure mode was higher in comparison to the columns that underwent global or mixed global—local failure. It was found that both steel and composite columns were able to carry axial loads in the post-critical state; but due to the limitations of local buckling of the steel cross-section in the concrete core and concrete confinement, all tested composite columns showed greater ductility than their steel counterparts.

“…The problem of the stability was later searched and analyzed further with a focus on many other relevant aspects for various engineering applications, like buckling of columns composed of various constructional materials (Gupta et al, 2001;Oleiwi et al, 2014;Schnabl et al, 2013;Kalamar et al, 2016;Thermou et al, 2018;Zhou et al, 2017;Ye et al, 2018;Osmani and Meftah, 2018;Wang et al, 2018;Naderpour et al, 2019;Qi et al, 2019), as well as beams (Ascione and Grimaldi, 1983;Di Sarno and Manfredi, 2012;Li et al, 2015;Ozbasaran et al, 2015;Monsalve-Cano and Aristizábal-Ochoa, 2016;Nguyen et al, 2018;Toufik et al, 2018) or nanobeams (Rahmani et al, 2017;Mohammadi et al, 2019).…”

In this study, a Finite Element Method (FEM) analysis is presented for the loss of stability in elastic states of very slender pinned without friction box-section thin-walled column axially compressed. From the FEM buckling linear stress analyses are determined the compressing critical forces for 36 cases, presented in tables and as the surface functions in dependence on the slenderness ratio and cross-section. Also are presented graphs obtained from the FEM post-buckling linear stress analysis for the elastic central line, slope, deflection and states of the stresses and strains of the box-section column 202812500 mm made of steel, by the assumption that a maximal deflection equals the half of a side dimension. The obtained from the FEM computing function and surface graphs are compared and then discussed with graphs corresponding to Euler's and Technical Stability Theory (TSTh) results. Finally are compared graphs of the stresses and strains of box-section thin-walled column 202812500 obtained from FEM and TSTh, but under compressing critical force determined according to TSTh.

“…Simultaneously, the eccentrically compressed columns were also investigated by Sheehan et al [13], Zha et al [14], Ren et al [15], Qiu [16], and Yang et al [17]. On the other side, systematic finite element analysis [18][19][20][21][22] was performed to simulate elliptical CFST columns subjected to concentric and eccentric axial compression. However, these studies mainly focused on static behavior, and research on their seismic behavior is very limited, which may hamper the application of elliptical CFST members in the seismic region.…”

Elliptical concrete-filled steel tubular (CFST) column is a new form of CFST columns, consisting of an outer elliptical tube filled with concrete. Although the study on mechanical performance of the elliptical CFST members is receiving more and more attention, they have been limited to static behavior. Against this background, an experimental study on elliptical CFST columns was carried out under combined axial compression and cyclic lateral loading. The failure modes, hysteretic curves, skeleton curves, load carrying capacity, deformability, stiffness degradation, and energy dissipation ability was obtained and discussed. The test results indicated that the elliptical CFST columns possess excellent seismic performance and ductility. Valuable experimental data were provided for the formulation of the theoretical hysteresis model of the elliptical CFST columns.
