With the immense loss of life and property witnessed in the last couple of decades alone in India, due to failure of structures caused by earthquakes, attention is now being given to the evaluation of the adequacy of strength in framed RC structures to resist strong ground motions. In this paper we studied the behaviour of G+12 multi story building of regular and irregular configuration with five different structures such as bare frame, core wall, shear wall, dampers, and infill wall under seismic load. In this paper a G+12 multi story building is studied for Seismic load using ETABS. Assuming the material properties, dimensions of beam and column for the analysis and the analysis are carried out by two different methods such as Response Spectrum Analysis and Equivalent Static Analysis method. After analysis the results such as Storey displacement, storey drift, storey stiffness, time period and base shear were compared with different models and also the effects of infill wall and dampers on the bare frame were studied. For the analysis the different loads are considered as per IS 875 code. The seismic Zone V was considered and properties of zone V were taken according to IS: 1893-2002 part 1 code.
