Comparative Study of Diagrid, Simple Frame and Shear Wall System

Diagrid Structure is one of the most unique structural systems that has been developed in recent years. For designing tall buildings there are various structural systems such as moment resisting frame, shear wall system, bracing system, space trusses, tubular structures etc. Diagrid is one of the new structural systems which is adept for designing tall buildings. In this paper, a comparative study between diagrid system, simple frame system and bracing system has been put forth. A 36-storeyed diagrid building, simple frame building and a building with Shear wall systems have been modelled and analyzed. The shear wall systems are provided as L-shaped at corners, provided at middle and provided at the core. The positions of the bracings have also been varied. A total of 12 buildings have been modelled and analyzed to compare which system performs better a lateral load resisting system. The modelling and analysis has been performed on ETABS. The dynamic analysis is performed by using Response Spectrum Method. All the loadings and the checks are provided as per Indian Standards.
