Influence of corner geometry on wind-induced forces in tall building models
Structural designers are compelled to opt for tall buildings to accommodate the growing population throughout the world. This research study presents a numerical analysis of tall building models, both regular and irregular in cross sectional shape, under the influence of wind forces. Wind load assessments were conducted using the computational fluid dynamics tool ANSYS CFX. The results are illustrated through various graphical representations, including pressure contours, mean pressure along the vertical centreline, and across the peripheral distance at different heights such as 250, 375 and 500 mm from the base of the model. Among the regular-shaped models, the rectangular chamfered corner design demonstrated superior wind resistance, while in the case of the irregular Y-shaped models, the design with corner cuts performed best in terms of resisting the strong wind and performed well in compression to other plan shape. The present research study also utilized the ANN-based forecasting model and different parameters are varied while the average surface pressure coefficient considered as the output. The findings indicated a strong co-ordination among the predicted outcomes and the given data, with a maximum forecasting error of less than 5%, was observed. The study concludes with a comparative analysis of irregular and regular-shaped models with equal floor areas, each featuring chamfered and filleted corners.
