Determination of the alongwind dynamic response of the CAARC standard tall building

Usually the structural behavior under wind action is evaluated by the Gust Factor Technique (GFT) which provides equivalent static forces acting on the structure. However, it is not possible to develop a more detailed dynamic analysis. Frequency domain analysis provides aclear description of the dyn...
