Performance Analysis of Regular and Irregular Structure Under Seismic Effect for RCC and Steel Composite Column Using Response Spectrum
Abstract
Composite construction is a modern method of construction presently holds a wide area of interest. This paper includes performance analysis of regular and irregular structure under seismic effect for RCC and Composite column. Modeling and analysis of structure is done by using ETABS software. Since composite construction is combination of steel section and concrete, which shows the properties of both steel and concrete. The compression efficiency of concrete and high ductile properties of steel together contributes to the structure for its perfect durability.

Introduction
Composite construction has become common technique in the field of construction. Since it is a combination of steel sections and concrete which add ups the properties of structure in its durability as well as strength. It should be noticed that efficiency of tensional property of steel and resisting property against corrosion also adds up the overall behavior of the structure. We all know that steel section is more prone to buckling but concrete resist the buckling, together as a composite unit which contribute high strength for structure, hence composite structure holds a high value of safety.
Conclusion
It is observed that displacement in regular structure having rectangular composite column is reduced to 40% to 50% as compared to same structure with rectangular RCC column.
It is observed that shear in regular structure having rectangular composite column is increased to 60% to 70% as compared to same structure with rectangular RCC column.
It is observed that drift in regular structure having rectangular composite column is increased to 35% to 40% as compared to same structure with rectangular RCC column.
It is observed that displacement in irregular structure having circular composite column is reduced to 40% to 50% as compared to same structure with circular RCC column.
It is observed that shear in irregular structure having circular composite column is increased to 60% to 70% as compared to same structure with circular RCC column.
It is observed that drift in irregular structure having circular composite column is increased to 35% to 40% as compared to same structure with circular RCC column.
