Study of Behaviour of High Rise Buildings with Diagrid Systems

High-rise structures are growing speedily around the world. The unique geometric arrangement of the system provides the efficiency of structure and beauty capabilities; the new structural system with diagrid has been used extensively for the recent high buildings. The diagrid is an arrangement of triangulated beams; it has a straight or curved and horizontal ring system which makes the combined structural system for skyscrapers. Diagrid structure uses fewer materials than traditional structural systems with orthogonal members. The efficiency of diagrid system reduces number of inner columns so that the design of the plan gets more flexibility. This research study aims to explore the applicability of diagrid systems in high-rise buildings, over conventional construction systems. A square plan 32 m × 32 m dimensions is taken to study of behaviour of high rise building with a diagrid system. All structural members like beams, columns, etc., are analysed considering all load combinations as per IS 800:2007. Similarly, analysis of G + 40-, G + 60- and G + 80-storied structures with diagrid system is taken for comparison of the results for parameters like storey shear, storey drift and storey displacement which are also represented in paper. For modelling and analysis purpose, ETABs software is used.
