Experimental study on concrete filled double tubular steel columns under axial loading
Abstract
Centric axial loading tests of twelve specimens of concrete filled double tubular steel columns were carried out. The specimens consist of concentric double steel tubes and filled concrete between them. Typical failure mode observed was a diagonal slip mode of the concrete associated with local buckling of both tubes. Their axial strengths could be estimated by a similar equation for an ordinary concrete filled steel tube with a single tube.
