Abstract :

The correct estimation of the wind forces acting on tall buildings is very essential for the safe design of structural elements. The influence of static & dynamic velocity fluctuations on the along wind loads for these structures are determined using Force coefficient method & Gust Factor Method respectively. In this Paper 60 m & 120 m buildings is analyzed using both the codes using ETABS Software v9.6 is done with variations in four Terrain Categories & Six basic wind speeds. Both codes are used for analysis and results (calculations of S.F, B.M & Displacements) obtained are compared and discussed.
