Background/Objectives: Steel-concrete composite system of construction has widely accepted all over the world as an novel, alternate and additional method of construction over the existing conventional pure steel and concrete construction. In India, this new concept is under the verge of popularity and also most of the building structures were built as low rise buildings. Composite construction combines dynamic properties of steel and concrete at its maximum extent to provide appreciably a greater strength and stability for the framed structures. The major objective of this paper is to compare a framed structure made by Reinforced cement concrete and Composite material located in earthquake zone of…show more content…
On comparison of the framed structures, the R.C.C structure imposes more dead load and carry higher bending moment. From the analysis results, its clearly shows that the inter storey drift for composite structure is comparatively more than RCC structure in both transverse and longitudinal direction but are accepted to be in desired (permissible) limits. It has been found from the study that use of composite members in construction is more effective and economic than using reinforced concrete members. The overall performance of manufacturing and construction techniques is improved to higher extent by the usage of composite materials in construction.
Applications/Improvements: Composite structures are found to be the best mode of construction for high-rise building while comparing with the conventional R.C.C structures as they serve well for various parameters like deflection, stiffness, story drift and lesser dead weight.

Many structural engineers in indian scenario are not welcoming the use of steel-concrete composite buildings because of its unfamiliarity, lack of awareness and its analysis and design seems to be little complex6. But literature quotes that if proper configuration is adopted, then steel-concrete composite structures can provide effective and economical systems of structural frame with greater stability & durability, rapid erection and effective seismic performance characteristics7. The real attraction of composite construction is based on having an effective connection between structural steel and reinforced concrete, and it is this connection that allows a transfer of forces and gives composite members their unique
