Analysis of Flat Slab Diagrid Building

High-rise buildings may place a premium on structural safety and the lowest possible level of harm. The structure must have sufficient lateral ductility to meet these requirements. This thesis examines the analysis and design of a 16-story flat slab diagrid building with a plan size of 18 m x 18 m. For modelling and analysis of structural members, the Staad professional software system is used. All structural members are designed in accordance with IS 456:2000, considering all possible load combinations. Seismic load is treated as a dynamic load in accordance with IS1893-2016 and is used in the structure's analysis and design. For a 16-story building, the load distribution in a diagrid system is also investigated. Similarly, diagrid buildings with and without flat slabs are analysed and designed, and the results are compared to conventional buildings. For seismic zone III, analysis values are compared in terms of Moment, Shear force, Displacement, Drift, and the economic aspect. The main goal of this thesis is to investigate the dynamic behaviour of buildings in seismic zone III, specifically diagrid and conventional frames. The parameters in both types of buildings are assumed to be the same for comparison purposes under the same seismic zone.
