Abstract: The objective of this paper is to analyze and compare the forces in G+5 and G+10 multi storied buildings for different wind speeds of 180, 200, 220, 240 and 260 kmph having a height of 20m and 35m using ETABS as per Indian standards. This study shows how the beam and column design is affected by the height of the building. Comparison of volume of concrete and quantity of steel is done for the whole building and also comparisons made for the internal forces like support reactions, bending moment, beam sizes, column sizes, percentage of reinforcement for different wind speeds. Also the lateral storey displacements, story shears and storey drifts are analyzed for the above wind speeds of the same structure.

Keywords: Wind effect, Multi storied building, Storey displacements, Support reactions, ETABS.
