Wind is a phenomenon of great complexity because of the many flow situations arising from the interaction of wind with structures. Wind loads as specified IS: 875 (Part 3) - 1987 are considered in the analysis. In this project analysis of G +11 building carried out by using STAAD PRO. Analysis is done for various variations such as 1) Terrain with few or no obstructions having heights below 1.5 m. 2) Terrain with obstructions having heights between 1.5 to 10 m. 3) Terrain with numerous closely spaced obstructions having the size of building structures up to 10 m in height. 4) Terrain with numerous large high closely spaced obstructions. According to Internal Pressure Coefficients (Cpi) provided for that various variations. This analysis is done for wind speed 44 m/s, 47 m/s, 50 m/s. Results obtained from STAAD-PRO analysis are used for obtaining significant relations of moments, forces and displacement with wind speeds. Moments, forces and displacement obtained from all cases are compared with wind speeds, according to their percentage of opening provided for various variations.
