Earthquakes are natural calamities that are characterized of releasing large amount of energy in the form of vibrations that damage structures. Base Isolation techniques help in decoupling the structure from its foundation thereby improving its performance. This article aims to study the response of G+3, G+10 and G+20 building models with different types of isolators (Lead rubber bearing and Friction Pendulum bearing) in respect of base shear, inter-storey drift, inter-storey displacements, frequency and time period when analyzed by different philosophies of analysis procedures (Equivalent Static Force Procedure[EQS], Response Spectrum Analysis [RS] and Time History Analysis [TH]). The results of the parametric study were compiled and discussed in an effort to draw conclusions so as to be able to suggest the type of isolation to be adopted.
