TY  - JOUR
AB  - A comprehensive experimental investigation into the axial compressive response of concrete-filled double skin tubular (CFDST) sections with stainless steel square and rectangular outer tubes is presented. A total of 28 tests was carried out. The experimental setup and procedures are  described,  and  the  test  observations  are  fully  reported.  The  test  results  are  employed  to assess  the  applicability  of  the  current  European  and  North  American  design  provisions  for composite  carbon  steel  members  to  the  design  of  the  studied  CFDST  cross-sections.   Modifications to the current design codes are also considered—a higher buckling coefficient k of 10.67 to consider the beneficial restraining effect of the concrete on the local buckling of  the stainless steel outer tubes and a reduction factor η to account for the effective compressive strength of high strength concrete. Overall, the comparisons revealed that the existing design rules may generally be safely applied to the prediction of the compressive resistance of CFDST cross-sections with stainless steel outer tubes, while the modified design rules offered greater accuracy and consistency.
