Comparative Study on Seismic Behaviour of RC Structure with Framed Tube Structure and Shear Wall for Different Stories

Abstract

Abstract This paper presents a comparative study on the seismic behaviour of reinforced concrete (RC) structures with framed tube systems and shear walls for different numbers of stories. Using ETABS software, the study intends to assess how well these structural systems perform when subjected to seismic and wind loads. The study focuses on tall structures in a particular seismic zone. Buildings with varied story counts (40, 50, and 60) and a standard area of 1600m2 (40m x 40m) are included in the analysis. Storey displacements for both lateral load resisting systems were evaluated. The Response Spectrum Method was used to analyse the structure. The results show that the framed tube structure exhibits superior seismic resistance compared to the shear wall system. It exhibits reduced displacements, higher drift ratios, base shear forces, and enhanced structural ductility. These results suggest that the framed tube structure can be a practical substitute for tall buildings in seismic areas. To avoid excessive deformation and failure, it is important to remember that sufficient stiffness and strength must be guaranteed in the design of framed tube structures. Future studies should also investigate how material characteristics, loading patterns, and interactions between the earth and the structure affect how seismically stable these structures are. This study has important implications for high-rise building design and construction in seismic areas. The framed tube structure's better earthquake resilience demonstrates how reliable a solution it may be.
