Wind interference effect on a hexagonal-shaped high building with orifices

Abstract

This research examined at how the wind load and pressure on a tall hexagonal structure varied as the apertures changed. Wind angles ranging from 0 to 90 degrees with a 30-degree gap were employed in various situations. The distance between the interference building and the model building was also gradually increased, at 50mm intervals, from 50mm to 200mm. The major building model was examined at a scale of 1:500. The validity of the ANSYS CFX package was also evaluated using a rigid model with dimensions of 100mm x 100mm and a height of 700mm. The k-ε -turbulence model was used in the study, which was carried out using Computational Fluid Dynamics (CFD) and the ANSYS CFX software package. To demonstrate the link between distinct scenarios, interference factors (IF) and contours were employed. Interfering buildings' impacts on the hexagonal-shaped building are explored. The pressure coefficient of the faces rises as the distance between the interference building and the model building grows. The impacts of apertures on the model building were also examined, with 5-20% openings given.
