Rapid urbanization and limited land availability in metro cities have led to a surge in the construction of multi-story buildings. tall buildings often face challenges such as vertical and mass irregularity, which can affect their stability during seismic events. Vertical irregularities (like sudden changes in stiffness) and mass irregularities (uneven weight distribution) increase vulnerability, making proper design and compliance with seismic codes essential. This highlights the need for advanced engineering solutions to balance urban growth with earthquake-resistant construction. This study examines the seismic performance of vertically irregular RC buildings (G+4, G+9, G+14) in Zone V (IS 1893:2016), focusing on mass irregularity effects. Using ETABS, models are analyzed via Equivalent Static and Response Spectrum Methods to assess base shear, storey displacement, and inter-storey drift. Results reveal structural vulnerabilities caused by irregularities, guiding safer designs for seismic zones while addressing limitations of standard analysis approaches for irregular structures.
