ABSTRACT The paper presents response of tall buildings using Computational Fluid Dynamics (CFD) software subjected to constant and varying wind velocity. The response of the buildings when subjected to wind load is studied by creating the models in ANSYS. Twelve models were chosen from previous wind tunnel studies and were subjected to constant and varying wind velocity in FLUENT. Through a comprehensive investigation on the buildings of different aspect ratio, wind-induced response of the structure is predicted. A Comparison of the CFD analysis with the previous studies are made. It is observed that the aerodynamic performance is different for solid-air interaction, when the velocity is varying along the height.
