Since liquid storage tanks play a vital role in the modern CPI, almost all the current studies have been carried out around the tank. The damage estimation of liquid storage tanks is a challenging problem, as the fluid-structure interaction exhibits extremely complicated and non-stationary response behavior . In the context of multi-hazard coupling effects, this problem becomes more difficult. Complex and time-consuming computational processes remain inherent drawbacks of numerical simulation methods . Thus, the empty tanks are usually regarded as the research object , which is inconsistent with actual application scenarios. Moreover, the corresponding equipment damage experiments are urgently required to verify the obtained numerical simulation results . Most related studies focus on the technological hazards coupling scenarios such as fire-explosion or multiple fires. These advanced numerical simulation methods are still considered to be a promising tool to support the analysis of other complex multi-hazard coupling scenarios.
