Influence of Across-Wind on Rectangular Tall Buildings
This study centered on investigating the effect of wind loads on tall rectangular buildings, particularly with various aspect ratios. The aim was to assess the across-wind base shear and moment of tall rectangular buildings using both experimental methods and an Ansys Fluent 2024 analysis. The results were compared between different sections with various aspect ratios according to Australian and Indian building codes. Six models with rectangular sections were employed, with three models measuring 20 m × 60 m and the remaining measuring 20 m × 80 m, to analyze the force measurements at different pitch angles ranging between 0° and 90°. All six models with various aspect ratios (1:3:7, 1:3:8, 1:3:9, 1:4:7, 1:4:8, and 1:4:9) were used to test the forces in both open and urban terrains. In conclusion, this study highlights the major factors that impact the design of tall rectangular structures. A new formula was developed to estimate the across-wind spectrum coefficient, which was followed in the across-wind force and moment calculations in IS 875-Part III:2015. From this study, it is evident that, through advanced techniques such as computational fluid dynamics (CFD) simulations, designers can gain insights into pressure distributions and make informed decisions to optimize the performance of buildings against wind loads.
