During an earthquake, failure of structure starts at points of weakness. This weakness arises due to discontinuity in mass, stiffness and geometry of structure. The structures having this discontinuity are termed as Irregular structures. Irregular structures contribute a large portion of urban infrastructure. The object of the present work is to compare the seismic behavior of regular building with horizontally irregular buildings. For this purpose four multi-storey buildings are considered and provided with and without shear walls. Building 1 is regular plan, building 2 is of L shape, building 3 is of T shape and building 3 is of C shape in plan. To study the behavior the response parameters selected are lateral displacement and storey drift. All the buildings are assumed to be located in zone IV. For analysis ETAB 2015 software is used.
