Abstract

In recent years using of base isolation systems due to improve in seismic performance of liquid storage tank was expanded. In this paper, the seismic behavior of the Liquid storage tank supported on DCFP isolation system under seven ground motions was investigated. The effects of essential parameters including slender of tank, period and coefficient of friction of the isolation system were investigated. In the parametric study, mass of liquid was idealized as convective mass, impulsive mass and rigid mass. In this analysis simplified three-degree freedom model to represent flexural and rocking vibrations of the tank was used. The results represent increasing of the slender ratio increases base shear and isolators forces and affects slightly on drift and isolation displacement. It is also shown that the period of isolators affects significantly on relative displacement of convective mass and isolators are remarkable.
