摘要：Earlier in 19th century, there were no structures as tall buildings but with the technological advancementand rise in urbanization, there was a need for vertical expansion of cities. During that era, for design purpose, onlyvertical/gravity loads on buildings were to be considered but with increase in slenderness/height of buildings, lateralloads on structures i.e. wind loads and earthquake loads came into pictures which are more predominant. In 1930s’many high rise buildings were constructed across the world. It was a period of great prosperity for high rise buildingsas extensive research work was carried out on wind induced effects on high rise buildings. Unlike the mean flow ofwind, which can be considered as static, wind loads associated with gustiness or turbulence rapidly and even abruptly,creating effects much larger than if the same loads were applied gradually. Wind loads, therefore, need to be studied asif they were dynamic in nature. CFD analysis becomes the most popular for such wind induced response studies. Thisresearch is mainly concentrate on wind induced pressures which would be arises due to wind intensity and howpressure varies according to different shapes of buildings. The intensity of a wind load depends on how fast it variesand also on the response of structure. Ansys Fluent has been used for CFD analyses to study the wind induced response.
