Geographical location of Bangladesh makes it ideally suited to earthquake and wind pressure. So, the knowledge of dynamic analysis is essential for civil engineers to design a safe structure for reducing the damages of structure during lateral loading. This paper represents a comparative study of the severity effect of wind forces on a high-rise building applying BNBC 2006.To achieve this goal a plan of 10 storied high-rise building has been considered. The study performed with 12 variation of wind speed from 150 km/hr to 260 km/hr. The analysis has been done by using computer software ETABS. After the analysis the maximum displacement was found 12.9 inch at 260 km/hr wind speed with top storey drift was found 0.0191 at 110ft whereas the lowest displacement and drift value was found 8.875 inch and 0.0153 at wind speed of 150 km/hr considering similar height of 110ft. This paper overviews the entire effect of different wind speed on high rise structure to predict the lateral movements such as displacement and inter-storey drift as well as serviceability of a RC building.

So there has been a considerable increase in the number of tall buildings, both residential and commercial and the modern trend is towards the taller structures. Considering the increasing population as well as lack of horizontal expansion is not a reasonable solution. If high rise buildings are constructed than many structural problems arise, such as lateral load effect, lateral displacement and stiffness etc. Generally, for high rise structure not only earth quake load effects are dominant but also wind load effects are dominant. Therefore, for high rise buildings it is essential to have knowledge of various loads and its effect on buildings. The effect of lateral load is very important to consider such as earthquake and wind loads. In some cases, the wind load is dominant than earthquake load which depends on area and zone factor defined by codes. Wind as a moving air has an effect on effect on building structures. Wind actions fluctuate with time, hence its effect on different situations and structures should be carefully analyzed. Wind act directly on the external surfaces of enclosed structures, through porosity of the external surface, internal surface through opening. Wind pressure act on areas of the surfaces
