: Investigation for the earthquake response has been carried out of isolated liquid storage steel tank with variable radius friction pendulum system (VRFPS) under normal component of earthquake excitation. The consistent fluid mass of the tank is demonstrated as lumped masses known as impulsive, convective and rigid masses. Motion equation which are governing on liquid storage tank is solved using Newmark’s linear acceleration method. The efficiency comparison has been made between response of isolated liquid storage tank using VRFPS and response of the same tank isolated with Friction pendulum system (FPS). It is observed that base shear, impulsive displacement and convective displacement are reduced in VRFPS as compared to that of FPS. Displacement which is Isolator and residual are more in VRFPS as compared to that of FPS.
