Comparative Study on Multi-storey Structure of R.C.C and Composite Material


Background/Objectives: Steel-concrete composite system of construction has widely accepted all over the world as a 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 IV (G+20 storey) with the plan dimension is 30m x 24m. Various aspects like story displacement, story drift, deflection and stiffness were studied and compared. Methods/Statistical analysis: The method of Equivalent Static analysis has been preferred in the current scenario of analysis. For the seismic analysis (IS-1893-2002), SAP2000 software has been used. By using Extended-three dimensional Analysis of Building Structure (E-TABS) software. Findings: The wind force effect and seismic response of steel-concrete composite frames are in the desired limit in comparison with R.C.C structures. 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.
