This paper investigates the structural behavior of reinforced concrete (RCC)-twisted buildings
subjected to seismic loads using ETABS software. The study focuses on analyzing various degrees of
twist in RCC-twisted buildings, specifically examining the angles of 1.5, 2, 2.5, 3, and 3.5 degrees per
floor. The study looks at how these different twist rates affect important structural parameters like base
shear, story displacement, and story drift through detailed modeling and analysis in ETABS. The
objective of this project is to determine the optimal angle of twist for RCC twisted buildings to ensure
structural integrity and performance under seismic conditions. By systematically analyzing twisted
buildings with incremental twist angles of 1.5, 2, 2.5, 3, and 3.5 degrees per floor, the study aims to
identify the relationship between the rate of twist and the resultant seismic behavior of the structures.
The results obtained from the ETABS simulations will be presented in detailed graphs and tables,
illustrating the variations in story displacement, story drift, and base shear for different twist angles
across multiple storys. Ultimately, this research seeks to enhance the understanding of how twisting
impacts the seismic resilience of tall buildings, providing valuable insights for the design and
construction of safer, more efficient RCC-twisted structures. The findings of this study will contribute
to the development of guidelines and best practices for engineers and architects involved in the design
of twisted high-rise buildings in seismically active regions.
