Natural gas as a clean fuel of the world demand for the trend is gradually increasing demand for clean energy in the country and there is growing interest. Therefore, LNG storage tanks and related facilities in the country of the importance of leading a community-based facility has emerged. So common sense that an earthquake with a seismic isolation device LNG storage tank similar to the actual behavior of the analytical model which can describe the development and construction of storage tanks to enhance the safety and economic design techniques need to be developed. In this study, a base isolation system, seismic analysis procedure of LNG storage tanks, and Triple-FPB developed a mathematical model of the present crystallized and complexity factors to the sum over histories model simplifies the complex behavior of the LNG storage tank with base isolation system how to interpret the seismic isolation is proposed.

A viscoelastic damper model which has a non-linear spring as an element is studied. The model is useful for expressing the non-linearity of viscoelastic materials. A time integration of constitutive differential equation shows non-linear hysteresis curves which have the qualitatively similar behavior of real viscoelastic materials. Harmonic balance method is used to get an analytic solution of system equations, which gives the frequency response curves. A direct time integration of system equation shows the periodicity of time response of system. The result of time integration shows that the harmonic balance method can be used efficiently. Jump phenomena of system response has been found.
