Abstract: | This study focuses on analyzing wind pressure on tall buildings with a square cross section, particularly examining the combined impact of corner modifications and the inclusion of large openings. The analysis is conducted using Computational Fluid Dynamics (CFD) in ANSYS Workbench, applied to models scaled at 1:100. Specifically, the corners of the buildings are altered to include recessed corners and chamfered corners, while the large openings are varied to cover 10%, 20%, and 30% of the building's frontal area. The aim is to determine how these design modifications influence the aerodynamic mean pressure coefficient (Cp) and the pressure distribution across different faces of the building models. By comparing these results, the study seeks to identify the configuration that minimizes wind load on the structure. In essence, the research explores innovative structural modifications that can effectively reduce wind-induced stress on high-rise buildings. Recessed and chamfered corners are two structural adjustments examined for their potential to disrupt wind flow and reduce pressure on the building's surface. Additionally, varying the size of large frontal openings is analyzed to understand how these gaps can alleviate wind pressure by allowing airflow through the building rather than around it. The findings from this CFD analysis are critical as they provide insights into optimizing the design of tall buildings to withstand wind forces. By identifying the corner modifications and opening sizes that result in the lowest wind loads, architects and engineers can enhance the resilience and stability of skyscrapers in urban environments. This research contributes to the broader field of structural engineering by offering practical solutions to the challenges posed by wind loads on tall buildings, thereby supporting the development of safer and more sustainable urban landscapes. |
