520			_aIn this study, the experimental and numerical investigation of concrete filled double tube (CFDTS) columns subjected to axial compressive load is investigated. The parameters studied are load carrying capacity and ductility index. The influence of normal concrete (NC), special concrete (SC) (Fine aggregate is a combination of 60 % river sand and 40 % ferro chrome slag) and fiber reinforced special concrete (FSC) (Fine aggregate is a combination of 60 % river sand and 40 % ferro chrome slag and crimped steel fibers of 2 % of by weight of cement with aspect ratio of 60 is added) on the behaviour of concrete filled double tube (CFDTS) columns are studied experimentally and numerically. In this study, 18 CFDTS columns (6 types) by varying types of concrete in core and shell portions are investigated. Load vs axial deformation obtained from experimental and numerical results are compared among various types. Special concrete and fiber reinforced special concrete has given better performance in CFDTS columns when compared to normal concrete.
