Abstract

This study aims to investigate the wind effects on the structures with vertical irregularities. The project employs ANSYS numerical simulation to investigate the wind effects with different plan shape. The primary objective of this research is to evaluate the wind effects in terms of wind generated effects in the high-rise structure. The building dimensions are scaled down according to the ASCE wind tunnel test manual, maintaining a length scale of 1:100 for CFD investigation. This method provides essential insights into wind pattern circulation and pressure distribution across various wind incidence angles. The wind flow pattern surrounding the structure reveals characteristics of flow separation and the creation of vortices in wake regions. The study indicates that the plan layout and sizes of the model directly influence the distribution of wind pressure on its different faces. In both cases, there is positive pressure on the windward side
