Popis: Cold formed steel is one of the structural materials which are vastly growing product and being used as various structural elements. It has major advantages in time effectiveness and the ability to shape it into the necessary shape even in room temperature. In this study the behaviour of the Steel column having flutes of different shapes when filled with concrete will be analytically investigated by analysing 8 column models using Finite Element Analysis software. Here Cold formed steel is to be used as the hollow section that confines the concrete. The Finite Element Analysis software that will use for the analysis is ABAQUS 14. All the specimens will be loaded with an eccentrically load and the results will be studied further. By providing the flutes along the longitudinal length of the column increases the moment of inertia and the stiffness of the column. The parameters of the column that will be varied for the analysis are the D/t ratios, Shapes of flutes and the thickness of the steel column. High Strength concrete of grade M50 will be used here in this analytical study. The thickness of the steel column used is 1 mm and 1.2 mm. The shapes of the flutes varied is rectangular flute and triangular flute. The maximum stress induced was in the column with 1 mm thickness with triangular flutes. And the maximum load was carried by the Triangular fluted column with 1.2 mm thickness.
