Abstract

The increasing demand for high-rise structures due to rapid urbanization necessitates the adoption of efficient lateral load-resisting systems to ensure structural safety, stability, and serviceability. This study presents a comparative evaluation of the seismic and wind performance of a Ground plus Fifty-storey high-rise building with an octagonal plan, incorporating different structural configurations such as shear wall arrangements and a diagrid system.A total of six analytical models, including a conventional bare frame, four shear wall configurations, and a perimeter diagrid system, were developed and analyzed using STAAD.Pro in accordance with relevant Indian Standards. The structural response was assessed in terms of lateral displacement, base shear, bending moment, and axial force under both seismic and wind loading conditions.The results indicate that the bare frame model exhibits maximum lateral displacement of approximately 2154 mm under seismic loading and 954 mm under wind loading, reflecting its low stiffness. The introduction of shear walls significantly improves structural performance, with optimally placed corner shear walls reducing seismic displacement by nearly 73% and wind displacement by about 71%. The diagrid system demonstrates enhanced overall efficiency, achieving a reduction of approximately 63% in seismic displacement and 37% under wind loading, along with improved control over bending moments and axial forces.Furthermore, shear wall configurations show higher base shear values (up to 3.18% increase), indicating increased stiffness and load resistance, while the diagrid system provides a more uniform load distribution and reduced torsional effects. The study highlights that while shear walls are highly effective in controlling displacement, the diagrid system offers a balanced performance in terms of stiffness, strength, and structural efficiency.
