However, the rubber support only has a shock insulation effect on horizontal earthquake load, the shock insulation effect on vertical earthquake is very small, but in the design of the storage tank, the vertical earthquake load cannot be ignored, for a dome which is a large-span cambered surface structure, the vertical earthquake response is far larger than that of the horizontal earthquake, and the vertical earthquake load is a control load; in addition, in the design of the inner tank, the acceleration of the vertical breathing mode of the liquid in the tank under the action of a vertical earthquake is 2/3 of the horizontal impact acceleration, after the rubber support is adopted for shock insulation, the horizontal earthquake acceleration is reduced by more than half, and the vertical earthquake load is not reduced to become a control load.
