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.
