Performance analysis and design of circular high‐strength concrete‐filled double‐skin aluminum tubular short columns under axial loading

Abstract: This study investigates the performance and design of high‐strength circular concrete‐filled double‐skin aluminum tubular (CFDAT) columns under axial loading. A new fiber element (FBE) model incorporating a new lateral confinement model is developed that considers the confinement effects and material nonlinearities. A new strength degradation factor is proposed for determining the postpeak behavior of the confined concrete in CFDAT circular columns. Existing experimental results are used to validate the accura… Show more

“…Similar to conventional CFST columns, CFDST members possess the outstanding properties of having high strength and good ductility [9]. In addition, compared with CFST members, CFDST members are lighter, have greater flexural strength, better seismic resistance, and excellent fire resistance [10][11][12]. Therefore, CFDST members are suitable for a range of practical applications, such as bridge piers, sea-bed vessels, transmission towers, legs of offshore platforms, etc.…”
