The aerodynamic performance of high-rise buildings plays a crucial role in ensuring structural stability and minimizing wind-induced forces, which can significantly impact both building safety and energy efficiency. This study investigates the effects of geometric modifications, specifically corner treatments like sharp and chamfered, on the aerodynamic characteristics of tall buildings. Additionally, the optimization of the height-to-chamfer ratio is explored to minimize aerodynamic forces such as wind load and pressure distribution. Computational Fluid Dynamics (CFD) simulations using ANSYS Fluent software are employed to analyze the aerodynamic forces under different building configurations. The results aim to provide an optimized design approach that enhances the wind resistance of high-rise buildings, contributing to more efficient and resilient architectural and engineering practices.
