The growth of population has influenced the construction of multistory buildings day by day. The construction of the building structures with conventional RC slabs are in the public eye since many decades. Although it has more stiffness and minimizes the large moments occurred due to the applied loads, it does not have the advantages in terms of architectural flexibility, easier formwork and shorter construction period compared to the flat slabs. This developing technique of flat slabs construction improves aesthetical and structural aspect of tall building, offices, hospitals, shopping malls etc. As this is considered to be beamless slab, it has less shear strength and less stiffness compared to the conventional slabs. Due to its huge advantages, it is common in both the construction of regular and irregular buildings nowadays. The main motive of the present work is to compare and observe the seismic behavior of G+13 storey of regular and different plan irregular buildings (Plus, T and U shape) by using different types of flat slabs (flat plate, drop panel, column head and combination of column head & drop panel) with the help of E-tabs 17.0.1 software. Later, conventional slab was adopted in the both regular & irregular models and analyzed in the similar way and compared with flat slab models intended for zone V. The nonlinear time history method was carried out to observe the different parameters like storey displacement, storey drift, base shear and time period following the guidelines of IS 1893 (Part 1): 2016.
