This study examines the behavior of high-rise buildings subjected to wind loads through a comprehensive analysis of structural responses and design considerations. Wind-induced effects remain a critical concern for tall structures, necessitating accurate prediction methods and robust design approaches. This research analyzed data from 15 high-rise buildings (150-350m tall) across three urban centers, employing computational fluid dynamics (CFD) simulations and wind tunnel testing to evaluate dynamic responses. Results indicate that helical and tapered geometries reduced wind-induced accelerations by 18-24% compared to prismatic forms. Damping systems demonstrated effectiveness in mitigating excessive vibrations, with tuned mass dampers reducing peak accelerations by up to 35%. Building orientation relative to prevailing winds significantly influenced both along-wind and across-wind responses. The study establishes correlations between building height-to-width ratios and critical wind velocities, offering empirically-derived design guidelines applicable to contemporary high-rise developments. These findings contribute to refining wind load estimation methods and optimizing structural configurations for enhanced performance and occupant comfort in tall buildings.
