###### Abstract
However, as storage tanks are being built larger, it is difficult to control the seismic response of storage tanks with seismic measures. In order to reduce the seismic response of the liquid storage tank, seismic isolation devices are introduced into the liquid storage tank structure, such as friction pendulum bearings, lead-core rubber bearings, etc. In order to study the seismic response of the isolated storage tank under the excitation of near-fault ground motion, [PERSON] et al. [17; 18] selected different isolation bearings for analysis. The research results show that the isolating affection of the variable frequency friction pendulum bearing is better than that of the friction pendulum bearing. [PERSON] et al. [19] derived the nonlinear restoring force expression of the multiple friction pendulum system, and studied the seismic response of the isolated storage tank on this basis. [PERSON] et al. [20] conducted shaking table tests on storage tanks with different isolation devices. The test results show that the horizontal displacement of the laminated rubber bearing isolated tank is the largest. In comparison, both friction pendulum bearing and variable curvature friction pendulum bearing have good isolation over a wider frequency band. [PERSON] et al. [21] investigated the multiple level performance of a seismically isolated elevated storage tank isolated with multi\(-\)phase friction pendulum bearing, and a mathematical formula involving complex time history analysis was presented for the analysis of a typical storage tank for a multiphase friction pendulum bearing. [PERSON] et al. [22] studied the seismic response of liquid storage tanks isolated by elastomeric or plain bearings; it was found that base isolation is quite effective in reducing the earthquake response of liquid storage tanks. The type of site has a significant effect on the seismic response of the storage tank. The foundation of the storage tank was considered as a rigid foundation in previous studies. In fact, the foundation frequently suffers from uneven settlement. [PERSON] et al. [23] conducted shaking table tests on rigid-foundation storage tanks and flexible-foundation storage tanks, and the results showed that the axial stress of flexible-foundation storage tanks was reduced compared to rigid-foundation storage tanks. [PERSON] et al. [24] proposed a detailed numerical framework for seismic analysis of liquid storage tanks considering soil-structure interaction (SSI), and studied the effect of SSI on the seismic performance of storage tanks. In summary, the current research has made great progress in the field of seismic resistance (seismic isolation) of storage tanks. However, some researchers' studies are based on simplified mechanical models or numerical simulation models, without conducting a shaking table test to verify their results. A few researchers have carried out shaking table tests, but their studies lack the numerical simulation to prove it. In view of this, this paper analyzes the seismic response of the storage tank model based on the shaking table test and numerical simulation, and studies the seismic isolation effect of the lead-core rubber bearing on the storage tank. On this basis, the dynamic response of a large LNG storage tank of 200,000 cubic meters under earthquake action is analyzed, and the seismic isolation pattern of the storage tank is studied.
