In this paper an attempt has been made for comprehensive numerical study of wind effects on tall building considering temperature effects. For that a tall structure having different geometric plan configuration of same plan area have been considered. All the tall buildings with different plan configuration have been modeled in CFD Code namely Fluent / Gambit and then comparative study has been executed. Distribution of the fluctuating surface pressure and the wind forces acting on bluff-shaped bodies are of great practical interest in the field of structural design in wind engineering because much civil and industrial structure can be assimilating to this shape. Computational wind engineering as a new branch of computational fluid dynamics (CFD) has been developed recently to evaluate the interaction between wind and buildings numerically. The techniques of Computational Fluid Dynamics (CFD), such as Standard k-ε Simulation, were adopted in this study to predict wind loads on and wind flow around the building. For the study, commercial Computational Fluid Dynamics (CFD) code Fluent has been used to generate computational domain around building then effect of temperature on static pressure, drag force and wind force coefficient on tall building has been examined.
