Abstract - This research investigates the influence of different shapes of skyscrapers on their aerodynamic performance in a particular wind regime. The shapes of the buildings are limited to geometric variations of high-rise buildings to understand the configurations and how they affect wind flow behavior and patterns around the buildings. It employs numerical simulations of wind flow and examines the impact of the form of the building shape on wind pressure pattern development and the loads imposed on a tall structure. The research includes the examination of design strategies that can be used to reduce the loads imposed by wind pressures on tall structures through the use of aerodynamically efficient forms. The impact analysis is framed in the context of comparative wind load stimulation of several different building forms while continuing to highlight a percentage reduction in wind loads through a more aerodynamic design modification. The results provide a detailed comparison and consideration of the shapes being evaluated, providing insight into their performance, understanding how different shapes not only changed wind flow but turbulence path behavior, and the overall impact this will have on developing more stable and sustainable forms in skyscraper design. This research explores aerodynamic shape optimization as a method to mitigate wind-induced loads via geometric modifications, leveraging Computational Fluid Dynamics (CFD) and optimization algorithms. The findings support integrating aerodynamic optimization early in architectural design, offering pathways toward more sustainable, high-performance high-rise buildings.
