Circular concrete-filled double skin tubular short columns with external stainless steel tubes under axial compression

Behaviour and design of square concrete-filled double skin tubular columns with inner circular tubes

“…In each group, different dimensions for the inner CHSs were employed to maintain the d/t i ratios. Design models for determining the ultimate strengths of short CFDST columns have been proposed by Hassanein et al [25] and Hassanein and Kharoob [8]. Additional models for concrete-filled stainless steel tubular (CFSST) short columns and the concrete-filled stainless steel-carbon steel tubular (CFSCT) short columns under axial compression have been developed by Hassanein et al [26,27], respectively.…”

“…Additional models for concrete-filled stainless steel tubular (CFSST) short columns and the concrete-filled stainless steel-carbon steel tubular (CFSCT) short columns under axial compression have been developed by Hassanein et al [26,27], respectively. Based on these design models [8,[25][26][27], a new design model for calculating the ultimate axial strengths of axially loaded short square CFDST columns with inner CHSs is proposed as:…”

Mechanical behavior of concrete-filled square steel tube with FRP-confined concrete core subjected to axial compression

“…A number of studies have investigated hybrid columns by combining different material components in a single column section to enhance structural performance. Typical hybrid columns include concrete-filled steel tube columns (CFST) [3][4][5], concrete filled fiber-reinforced polymer (FRP) tube columns (CFFT) [6][7][8][9][10], steel-concrete double skin tubular columns [11,12], and hybrid FRP-concrete-steel double-skin tubular columns [13].…”

CFDST stub columns having outer circular and inner square sections under compression

“…Next, partially loading and pure torsion tests on CFDST members have been carried out by Yang [14] and Huang [15]. Last, CFDST stub columns with external stainless steel [16,17] can be found.…”
