Abstract: Diagrids structural systems have emerged as most innovative way of approach to tall buildings in this era. Variations of the diagrid system have evolved to the point of making its use to construction of tall building. Investigation in depth on design methodology of Diagrids structures, gave the powerful structural strength and symbolic architectural view. The diagrid structure of each storey height is designed with diagonals placed at various uniform angles as well as gradually changing angles along the building height in order to determine the optimal uniform angle for each structure with a different height and to investigate the structural potential of diagrids with changing angles The comparison of 24-storey diagrid structural system with different uniform angles is presented here.. The 24 storey diagrid structural system with different angles are modelled and analyzed by using Etabs Software. Now a day the Non linear analysis is essential for a tall building, in this present study the non linear analysis is carried out for the considered diagrid structural system. The comparison of analyzed results in terms of top storey displacement, time period, storey shears and mode shapes is presented here.

Keywords: Angle of Diagrids, Displacement, Mode Shapes, Time Period, Storey shear, P delta etc…
