        abstract = {This review paper examines the impact of horizontal and vertical irregularities on the seismic performance of reinforced concrete (RC) and steel buildings, with a focus on provisions outlined in IS 1893 (Part 1): 2016 for India’s earthquake-prone regions (zones II-V). Horizontal irregularities (e.g., torsional, re-entrant corners, diaphragm discontinuities) and vertical irregularities (e.g., stiffness, mass, geometric) are defined and their effects on amplified seismic demands and collapse risks are analyzed. The paper synthesizes recent research, including novel seismic irregularity descriptors, base isolation for hillside structures, progressive collapse under column removal, and advanced seismic intensity measures for fragility assessment. Studies highlight the limitations of existing code provisions in addressing complex irregularities, particularly in high-rise and sloping-ground buildings, and propose solutions like tuned mass dampers, optimized design algorithms (e.g., ANN-PSO), and refined Rapid Visual Screening methods. Key findings emphasize the need for enhanced design guidelines to improve seismic resilience, integrating advanced computational and experimental approaches for accurate risk assessment and cost-effective structural designs in high-seismic regions.},
