Abstract :

In this experiment,Investigation on the behaviour of Circular Stiffened Hollow Steel Column filled with Self Compacting Concrete (SCC) subjected to monotonic loading is studied. In this study typical Twenty Four combinations of variable lengths and D/T ratios is considered. Three different length of specimen that is 238.2mm, 421mm & 538mm and three different diameter of specimen that is 15.88mm, 26.9mm, 42.1mm with same thickness 1.6mm are selected, in order to know the behaviour and buckling load of above said columns and tests were conducted under monotonic loading. From the experimental result it can be concluded that 1.As length increased, load carrying capacity decrease. 2. As diameter increases load carrying capacity increased 3. Load carrying capacity of steel tubes filled with SCC higher than the empty steel tube. 4.when compared to the Unstiffened Steel Tube Stiffened Steel Tube is stronger ,and load carrying capacity of stiffened steel tube is also higher
