Evaluating the Seismic Behavior of RC Structures: A Comparative Study of Framed Tube and Shear Wall Systems for Varying Numbers of Stories

Abstract

Abstract Through a comparison of framed tube systems and shear wall systems for various story counts, this work evaluates the seismic behaviour of reinforced concrete (RC) structures. The goal is to use the ETABS software to evaluate how well these structural systems perform when subjected to seismic and wind loads. Analysis of storey displacements, a crucial performance metric for both lateral load resisting systems, is the study's main objective. To analyse structures, we use the Response Spectrum Method. The findings show that the framed tube structure outperforms the shear wall system in terms of seismic resistance, showing decreased displacements, greater drift ratios, increased base shear forces, and improved structural ductility. These results imply that framed tube structures can be used as workable substitutes for tall buildings situated in seismic regions. To avoid excessive deformation and failure, it is necessary to include enough stiffness and strength in the design phase. The study also highlights how crucial it is to look into how material properties, loading patterns, and interactions between the structure and the ground affect these systems' seismic stability. The findings of this study show the earthquake resistance and dependability of framed tube structures and have major implications for high-rise building design and construction in seismic regions.
