Earthquake forces excite the structure and sets it into vibration in a short time. It is understood from the past earthquake events that buildings with irregularities in its configuration are more vulnerable to earthquake damages when compared to buildings with regular configuration and elevation. In the present study two buildings are designed, one in regular(rectangle) and the other in irregular(plus) shape in plan with same beam, column, slab thickness and plinth area and are analysed in various seismic zones with different soil conditions using Response spectrum analysis (Linear Dynamic analysis) to study the variation of Storey drift, Base shear, Support reactions and Storey displacements and to draw a comparison between the regular and irregular (in plan) buildings. Rectangular
and Plus shaped buildings both are designed as symmetrical in plan and the study is carried out with help of Staad pro software.
