Abstract:
The decades have seen outstanding advances in the use of composite steel-concrete structural systems in the construction of tall buildings. Concrete-steel composite structure is defined as a construction in which both steel and concrete materials are combined to maximize the structural and economic advantages of each material. Composite column enhances the rigidity of the structure and provide significant axial load carrying capacity. Composite columns are generally classified as concrete filled steel tubular columns and encased columns. Encased columns are also known as Steel Reinforced concrete columns. Tubed steel reinforced concrete column is special type of composite column which have reinforcing bars in the form of steel tube on the perimeter and steel shape at core of the column. When concrete filled steel tube is used, the strength of concrete is increased due to the confining effect provided by the steel tube, and the strength reduction is not very severe, since the tube prevents the spalling of concrete. The purpose of the current research is the compare the tubed steel reinforced concrete column with steel reinforced concrete columns and conventional columns based on axial load carrying capacity by using finite element analysis software ANSYS17. And also conducted parametric study by varying steel shape, length of column and thickness of steel tube. ISMB150, ISMB125,ISMB100 are used for steel shape. The results show that when the thickness of column is increased by one mm, 8.043 % reduction developed in deformation of columns under constant load. When length of the column is increased by 200 mm, deformation is also increased.
