Abstract
Composite construction with columns made of double-skin steel tubulars filled with concrete (CFDST) which have a concrete infill between the exterior and interior tubes made of steel. The thickness of steel tube, hollow section ratio and the concrete stress–strain are the variables that affect the axial load behaviour of Steel-Concrete-Steel Double Skin Tubular Columns. This study's goal is to use the Abaqus 6.20 software to examine the axial behaviour of CFDST columns. The hollow section ratio is explored by altering the inner diameters (26.9 mm, 33.7 mm, and 43.4 mm) while maintaining a constant outer tube diameter of 114.3 mm in the parametric investigation on the columns. The hollow section ratio of 0.24 proves to be most effective and has increased load carrying capacity.
