The flat slab system has become increasingly prevalent in modern building construction due to its ability to satisfy economic and architectural demands by reducing floor heights. Compared to conventional moment resisting frames, reinforced concrete buildings utilizing flat slabs exhibit numerous advantages. Despite the fact that flat slab construction offers several advantages over conventional moment resisting frames, its ability to withstand seismic loading is limited, thus reducing its overall structural effectiveness. Despite numerous studies conducted by various authors in recent years, the behavior of flat slab structures under lateral-displacements remains poorly understood. Nevertheless, flat slabs continue to be popular even in areas prone to earthquakes. This present study involves the analysis and comparison of a 12-story flat slab reinforced concrete structure with vertical and mass irregularities subjected to lateral loads according to IS codes. The primary objective of this work is to analyze and compare irregular flat slab reinforced concrete structures with and without lateral force resisting systems, such as shear walls and bracing systems. Etabs software is utilized to conduct the structural analysis. For structures with vertical irregularities, dynamic analysis is carried out in accordance with IS 1893:2002 (part 1), and various parameters, including base shear, time period, story drift, story displacement, and story stiffness, are compared for these structures.
