In this study, the loading pattern of skewed and orthogonal wind condition is analysed to find how much increased or reduced response. As the height of the buildings increases, its vulnerability to wind effects also increases. Codes and Standards utilize the “gust loading factor” (GLF) approach for estimating dynamic effect on high-rise structures for 0, 45 and 90 degree. At the real situation of wind load, these conditions are not covered for strong wind responses. In order to get the responses of other skewed wind direction, various type of loading patterns is assumed to apply the wind load. For the dynamic response analysis of a structure under strong winds, the spectral response method in a frequency domain or the step-by-step integration of motion equation in a time domain is used. This paper aims to make a comparison of various loading patterns of skewed and orthogonal wind in along-wind and across-wind response with respect to the gust response factor (GRF) of dynamic wind load on tall buildings. In this study, the model building is analysed for strong wind in Yangon area and costal area. Then, comparison of maximum structural responses for strong wind is studied.
