Experimental study on concrete filled elliptical/oval steel tubular stub columns under compression

Experimental study of slender concrete-filled elliptical hollow section beam-columns

“…In the context of concrete-filled elliptical hollow section (CFEHS) members, while the literature is currently fairly limited, previous experimental studies include compression testing of stub columns [32,33], testing of concentrically-loaded slender columns [34] and eccentrically-loaded columns [35][36][37]. The behaviour of CFEHS columns in fire conditions was also examined by [37].…”

Numerical analysis and design of slender concrete-filled elliptical hollow section columns and beam-columns

“…While testing was conducted by [4,30,31] on CFEHS stub columns, the present study focuses on more slender columns. The three main experimental studies used for validation of the numerical model and the assessment of design proposals in the present study are [34][35][36].…”

“…These studies provided a basis upon which design rules for steel EHS members have been formulated [28], including rules for compressive resistance [21], bending [23], flexural buckling [24] and shear [29]. In the context of concrete-filled elliptical hollow section (CFEHS) members, previous experimental studies include compression testing of stub columns [4,30,31], members in bending [32], concentrically-loaded slender columns [33] and eccentrically-loaded columns [34][35][36][37]. The behaviour of CFEHS columns in fire conditions was also examined by [35].…”

Experimental investigation on lightweight concrete-filled cold-formed elliptical hollow section stub columns

“…Design guides based on Eurocode methodology has also been proposed [6]. Concrete-filled stub columns primarily related to the normal weight concrete have also been investigated by researchers around the globe [7][8][9][10][11][12].…”
