The traditional method for seismic design of building structures i.e. strengthening the ductility, stiffness and strength of the structures has been in common use from a long time. The efficiency of the conventional methods is constrained. To resolve disadvantages associated with the conventional methods a number of vibration-control measures called structural control have been discovered and remarkable growth in this subject have been noticed over recent years. In this study a comparative seismic analysis of the multi-storey RC building is done with the variation in the base conditions. G+5, G+8 and G+10 building models are analysed with fixed base, natural rubber bearing, lead rubber bearing and high damping rubber bearing. The variation in the seismic zone is also considered for the analysis. Seismic parameter like time period, base shear and interstorey drift ratio are obtained and results are compared.
