Parametric study of Diagrid, Pentagrid and Hexagrid structural systems

Abstract

Diagrid structure is one of the most unique structural systems that have been developed in recent years. For designing tall buildings there are various structural systems such as moment resisting frame, shear wall systems, bracing systems, space trusses, tubular structures etc. Diagrid is one of the new structural systems which is adopted for designing tall buildings. In the present paper a comparative parametric study of Diagrid, Pentagrid and Hexagrid structural system has been done. A 13, 37, and 46 storey building with shear wall have been modelled and analysed for Diagrid, Pentagrid and Hexagrid structural systems. The shear wall of thickness 230 mm has been used. A total of 24 buildings have been modelled and analysed. The modelling and analysis has been performed using ETABS. The dynamic analysis is performed for earthquake by response spectrum method and for wind by wind dynamic analysis
(Gust factor method). From the analysis maximum storey displacement, maximum storey drift, base shear and fundamental time period parameters have been compared for all models.
