DOI: 10.1016/j.tws.2019.02.001
Abstract: Abstract Circular high-strength concrete-filled double steel tubular (CFDST) columns are high performance members where the internal and external steel tubes offer significant confinement to the concrete infill. The confinement remarkably improves the concrete compressive strength… read more here.

DOI: 10.1016/j.tws.2021.107898
Abstract: Abstract Concrete-filled double-skin steel tubular (CFDST) columns possess lower self-weight, higher ductility and energy absorption than conventional concrete-filled steel tubular (CFST) ones. The use of high-strength concrete (HSC) can further enhance their advantages, such as… read more here.

DOI: 10.1177/13694332231161109
Abstract: This paper reports the compressive behavior of concrete-filled double skin steel tubular (CFDST) columns strengthened by CFRP under axial loading. The outer skin was made of square hollow sections (SHS), while the inner skin was… read more here.
