High-Rise Building Wind Analysis Using Computational Fluid Dynamics and Dynamic Analysis Using ETABS Program

Abstract

Present paper is devoted to study wind load on tall building. Computational fluid dynamic (CFD) model was performed in three-dimensional (3D) commercial packages ANSYS (Fluid Fluent) 19.0. Utilizing finite volume technique to predict the wind load on tall building using specific boundary conditions. LES and standard k-ε turbulence model were used in the program to consider the wind turbulence. Current numerical approach was verified by comparison the drag coefficient and left coefficient results with experimental wind tunnel tests. This valid CFD model was applied in the simulation of the wind analysis for theoretical building, which is assumed located in Baghdad City, Iraq. It is connected that wind load results of CFD have a good agreement with the wind load results of building codes. This building was dynamically analyzed and good results were obtained.
