In these modern days, the structures are involved with architectural importance and it is highly difficult to plan with regular shapes. This leads to planning with irregularity in the structure. These irregularities are responsible for structural collapse during earthquake. It is observed that in the regular frame, there is no tensional effect in the frame because of symmetry. But in case of irregular structures due to the tensional effect between the beam column joints failure occurs. Among the different types of analysis, pushover analysis comes forward because of its optimal accuracy, efficiency and ease of use. In the present study, the behaviour of G+10 storied R.C frame buildings with different geometrical irregularities subjected to earthquake load considered and volume of all building kept same means all total number of rooms kept same in all building models. Also total height of building 33m kept for all shape building model. Located in seismic zone III is discussed briefly using ETABS software. Gravity loads and laterals loads as per IS 1893-2002 are applied on the structure and it is designed using IS 456-2000. Displacement control pushover analysis is carried out.
