COMPARATIVE STUDY OF STRUCTURE WITH OR WITHOUT DIAGRIDS UNDER LATERAL CONDITIONS

Construction of high – rise buildings is rapidly increasing day by day. There are huge advance changes in structural systems, materials, analysis & design software which are completely focused in growth of these high – rise buildings. Today’s tall building concepts are leading in architectural features of building geometry with strength resisting stable structure and stiffness, etc. Hence, there very good enhancing structural systems are coming up from all over the world & diagrid structural system is one these inventions which are made in Civil Engineering world. In present work, a hexagonal structure ofG + 25 is compared with or without diagrid structural system. Due to inclined columns, lateral loads are sustained by steel diagonal members which are provided as a steel diagrid structural system. The size of building is 75 x 63.25m of total 25 stories located in Zone III and analyzed by ETABS. Parametric study & detailed comparison of diagrid structural system w.r.t conventional structure. Various parameters like maximum displacement, mass participation ratio, mass participating direction factors, fundamental time period, maximum base shear, etc.
