“…CFSTs with regular cross-sections, such as circular, square and rectangular shapes, have been widely investigated [4], yet some research has been conducted on other cross-sectional shapes, for example, Chang et al [5] conducted an experimental and numerical study to investigate the static axial performance of stiffened concrete-filled double-skin steel tubular (CFDST) stub columns with circular and square shapes. In addition, Rahnavard et al [6,7] conducted experimental and numerical analysis on four different cross-section shapes of fabricated concrete-filled cold-formed steel (CF-CFS) short and long columns. For both long and short columns, it was found that the ultimate strengths of the concrete-filled columns were higher than that of hollow columns.…”

“…Cold-formed steel profiles have several advantages over those hot rolled, including shorter construction time, economic efficiency, and accessible transportation [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Extensive experimental, computational, and analytical research has been undertaken over the last decades to understand better the behavior of composite columns exposed to fire [15][16][17][18][19][20][21][22][23][24][25][26]. A simple design approach for CFST columns in a fire was provided by Ukanwa et al [19][20][21][22].…”

“…These structural components have high structural fire performance. Recently studies were carried out on applying cold-formed steel profiles and lightweight concrete instead of hot-rolled and normal concrete [1,2]. The cold-formed steel profiles have advantages over hot-rolled profiles, such as less difficulty in transportation, high strength-to-weight ratio, ease of fabrication, less construction time, ability to generate various cross-section shapes [3][4][5][6].…”

“…Understanding the behavior of these columns subjected to accidental fire action is necessary further to enhance the fire performance of such structural members. In the last few decades, a great deal of experimental, computational, and analytical work has been done to better understand the behavior of composite columns when subjected to fire [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Espinos et al [8] numerically compared the fire resistance of concrete-filled steel tubular composite columns and concrete-filled steel tubular composite columns with a steel core.…”
