Abstract:
Wind forces significantly influence the design of high-rise structures, especially as buildings become taller and more flexible. This research investigates the effectiveness of tapering and corner modifications in mitigating wind-induced vibrations in high-rise structures. The study analyzes two composite building models, a 50-story and a 100-story structure, subjected to a wind speed of 44 m/s. Different tapering ratios (0%, 5%, 10%, 15%, and 20%) and corner modifications (chamfered and corner cut) are analyzed using ETABS 2021 software. The results, including story displacement, story drift, base shear, and time period, are compared across different models. The findings indicate that tapering and corner modifications effectively reduce wind-induced vibrations, with higher tapering ratios generally leading to better performance. The study highlights the importance of considering aerodynamic modifications in the design of high-rise buildings to ensure structural safety and occupant comfort.
