This paper presents the experimental study of six Double Skinned Hollow Concrete Filled steel Tubular (DSHCFT) columns consisting of PVC inner and mild Steel outer pipes in-filled with Self Compacting Concrete (SCC). The grade of SCC and the yield strength of steel used were M35 and 250 MPa respectively. The Columns were tested for axial load and Loaddeflection, Ultimate compressive strength were studied and reported. The experimental results are verified with European Code (EC4) and found as conservative. The PVC tube is found as a reasonably suitable alternate material for moderately loaded DSHCFT columns.

This paper presents the experimental study of six Double Skinned Hollow Concrete Filled steel Tubular (DSHCFT) columns consisting of PVC inner and mild Steel outer pipes in-filled with Self Compacting Concrete (SCC). The grade of SCC and the yield strength of steel used were M35 and 250 MPa respectively. The Columns were tested for axial load and Loaddeflection, Ultimate compressive strength were studied and reported. The experimental results are verified with European Code (EC4) and found as conservative. The PVC tube is found as a reasonably suitable alternate material for moderately loaded DSHCFT columns.
