The term "building with soft floor" refers to a high-rise whose bottom floor is made up of open space. Such a floor is crucial to the building's seismic performance. This is as a result of the sudden shifts in lateral stiffness and strength brought on by such storey. Due to the current era's population growth, it is more difficult to obtain parking for apartments in crowded places. As a consequence, it is currently common practise to build multistory buildings with an open first level. Buildings with no infill masonry walls in the ground story but all above storeys enclosed by masonry walls are referred to as "Soft Storey" or "Open Ground Storey Buildings." Larger columns are shown to successfully prevent drift in irregular structures compared to regular buildings, although the shear force and bending moment on the first level rise. The Soft Storey structures perform badly during a strong earthquake. The main objective of this research is to evaluate the impacts of Storey overturning moments, Storey drift, displacement, and design Base shear on the behaviour of the building in a seismically active environment. An L-shaped building, a square building, a T-shaped structure, a plus shape building, and a C-shaped building are presented as examples of G-15 story buildings for comparison. The full collection of models is analysed using ETABS 2018 edition. In the present study, dynamic analysis has been looked at to evaluate the deformation of all five-shape buildings with and without soft storeys taking into account at various levels. Displacement is decreased when the soft tale is presented at a higher level. This study reviews a number of earlier investigations that were conducted on this issue. Reviewing research articles informed us of the definitive findings, which formed the foundation for the study's goal in the future.
