Tall building is the growing pattern of cities, these buildings are highly vulnerable to wind loads. Wind loads effects on the high-rise building can be found using wind tunnel testing and CFD tools. Wind tunnel facilities are limited all around the world, so CFD tools can be incorporated. In this study ANSYS CFX is used to investigate the effects of wind on different shape of high-rise buildings. Results of numerical simulation are compared with international standards of various countries. Stream line pattern and pressure contours on different faces are discussed in this paper. It is found that building shape and size are having the direct effect on the pressure distribution on various surfaces of building model. Wind ward face pressure will always be positive in nature.
