Buildings will always have some kind of irregularity about them. The behaviour of buildings with typical types of irregularities, including vertical and planar ones, has to be examined, especially in the context of earthquakes. The fundamental goal of earthquake engineering is to design and construct a structure in such a manner that the damage to the building and its structural components during an earthquake is minimised by taking the necessary safeguards. Seismic excitations may cause a wide range of damage to buildings. Damages in the system are not uniform nor consistent, even when accounting for the same structural structure, area, and earthquake. A building's seismic behaviour is determined by a number of factors, including the building's structural system, the nature of the earthquake, the building's quality, the soil in its location, and any repairs that have been made. The current research shows how both typical and atypical structures behave. Ten-story buildings are the focus of the current investigation. ETABS 2016 was used to create the building's model. This thesis analyses both regular and irregular schedules. For the sake of analysis, the X and Y axes are subjected to a variety of loads, including dead load, live load, and seismic load. According to NBC 105:2020, a number of load configurations are taken into account. An investigation into the seismic behaviour of buildings with regular and irregular plans is presented in this thesis. The primary goal of this study is to compare the seismic performance of buildings with regular and irregular floor plans. The current research analyses models of RCC buildings with G+9 storeys and both regular and irregular floor plans. Using the ETABS programme, we do a dynamic study of the model. Final comparisons of seismic response findings are made between various time periods; base shear, storey shear, member forces, overturning moments, displacement, stiffness, and drifts.
