The rapid increase of the urban population in developing countries such as India, has forced the reevaluation of the importance of high rise buildings. The structural systems of high rise buildings are usually sensitive to the effects of wind. Gust is the most critical effect of the wind. The gust effectiveness factor method takes into account the dynamic properties of the structure , the wind-structure interactions and then determines the wind loads as equivalent static loads. In this paper, same building with different corner geometry of various shaped is to be consider of height 180 m having equal stiffness of column are considered for wind load analysis. Wind loads are determined based on gust effectiveness factor method. The critical gust loads for design are determined. After the application of calculated wind loads to the building models prepared in finite element software package ETAB. having different shapes are compared in various aspects such as storey displacements, storey drifts, storey shear, axial forces in column etc. Based on the results, conclusions will be drawn.

Keywords : Storey displacement, Storey drift, Storey shear, Wind load.
