The diagrid structure has emerged into an innovative method in the recent construction field and has led to the advancement of tall buildings and high-rise structures not only in the engineering field but also in the architectural field. It has also made the structure stiffer and lighter when compared to the normal conventional buildings. However, recent studies on diagrid system reported insufficient energy dissipation capacity and inadequate ductility in high seismic zones. The limited ductility and energy dissipation capacity become critical under solid ground motion as diagrid elements carry both gravitational and lateral load. These diagrid members lose elasticity at certain deformations and start yielding leading to global collapse. The present work reviews studies regarding seismic performance assessment of diagrid structures with different arrangement of secondary bracing system. The diagrid structures are modelled with different arrangement of secondary bracing system and are analyzed using ETABS software. IS 1893: 2016 is considered for load combination of seismic analysis. Results show that secondary bracing system increases the seismic resistance of diagrid building. The X- arrangement of secondary bracing improves the seismic performance of building the most.
