Abstract - Composite structures render the eccentric possibility of ergonomic design of members and material in the case of vertical structures. Reinforced concrete structures are the traditionally preferred construction practice in most of the developing countries. A coalesced structural property of concrete and steel is achieved while using composite structures. Degrees of freedom plays a crucial role in enabling concurrent optimization in all aspects resulting in various ascendancies such as reduced structural weight, paramount dynamic stability, fire resistance, profitability, and, so on. This paper covers the review on the comparison of seismic behavior of composite columns with RCC columns under various physical conditions.
they conform to the relative strengths of both steel and concrete. The types of composite columns are concrete infilled, concrete encased, and double skin sections.
Key Words: Composite columns, RCC columns, Degrees of freedom, Seismic behaviour.

1. INTRODUCTION Composite structures render the eccentric possibility of ergonomic design of members and material. The rampant population growth has led to the need for vertical structures, owing to the privation of land. Degrees of freedom plays a crucial role in enabling concurrent optimization in all aspects resulting in various ascendancies such as reduced structural weight, paramount dynamic stability, fire resistance, profitability, and, so on. Geometric parameters are considered with limitations when conventional materials are pondered for construction since the degrees of freedom available will less in number. Datta., [1] proposed about the cost-effectiveness in steel composite concrete construction, for elevated buildings in particular. An insight about cost variation was also observed. The author further emphasizes the fact that steel-concrete composite construction will explicitly provide more carpet area and will turn out to be a sustainable up-gradation, in terms of environmental performance. The Net Construction Cost, quality of construction, tectonic stability were some of the major advantages discussed in brief. The optimum utilization of steel by the Engineers is insisted, to make the growth of Indian society more user- friendly matching with the National Housing and Habitat Policy and Housing needs of citizens. The components of the composite structure include composite beams, composite slab, composite columns, composite connections, and foundation systems. The composite column is attractive amongst all the elements as Š 2020, IRJET
