        abstract = {The rapid increase in population and urbanization has intensified the demand for land, making tall structures a critical solution to address space constraints. Historically, structural design primarily focused on resisting gravity loads; however, the rise in building heights and the understanding of seismic zones necessitate the consideration of lateral loads such as wind and earthquake forces. Advances in three-dimensional structural analysis and computational power have enabled the efficient and secure construction of taller buildings. Modern design approaches prioritize minimizing structural motion over traditional strength-based methods to ensure stability and performance.
This study investigates the seismic behavior of irregular building frames employing tube systems, which are increasingly favored for their excellent resistance to lateral forces and suitability for tall structures. A time history analysis was performed on six G+40-storey reinforced concrete buildings located in Zone-V, as defined by IS 1893. Among these, four buildings feature irregular plans, while two have regular plans, with all models designed without shear walls. The study examines the seismic performance of these buildings under the influence of mass-stiffness irregularity and setback-stiffness irregularity. Key parameters analyzed include overall building drift, storey drift, storey shear, storey acceleration, and storey torsion.
The findings of this research aim to provide insights into optimizing the seismic design of tall buildings, especially those with irregular configurations, contributing to the advancement of safe and resilient high-rise construction practices.},
