The different types of vibration-control measures like passive, active, semi-active and hybrid vibration control methods have been developed. Base isolation is a passive vibration control system. The isolator partially reflects and partially absorbs input seismic energy before it gets transmitted to the superstructure. L.R.B isolators are placed between the superstructure and foundation, which reduces the horizontal stiffness of the system. Three types of vertical irregularities namely mass irregularity, stiffness irregularity and vertical geometrical irregularity were considered. Modal analysis of G+14 regular R.C.C structure. Base isolation reduces the lateral displacement, shear forces, bending moments, base shear, storey acceleration, interstorey drift as compared to the conventional fixed base structure. This shows the effectiveness of base isolation and concluded that base isolation is very effective seismic response control device.
