Should the gravity of the material filling the container be considered when designing vertical containers?

The material buffer tank in question has a DN1000 diameter, a cylinder length of 2000, and is a vertical container with elliptical end caps at the top and bottom; ear-type supports are used. Under normal operating conditions, the filling coefficient for the material is 0.5. However, an emergency scenario may occur where the material outlet gets blocked while material continues to flow in through the inlet, eventually filling the container almost completely. At this time, the filling coefficient is 1); then when using SW6 to calculate the ear seat, how should the height of the medium inside the container be entered – as 1275 or as 2550? GB/T 150-2011 4.3.2 c specifies it as the gravitational load of the filling medium under normal operating conditions. If calculated as 2550, can the source be found?
Personal understanding: The maximum weight should be calculated for verification; therefore, it should be the height corresponding to the maximum amount of the medium
Based on a conservative estimate of the maximum mass, the tank is actually quite small, so it’s easy to meet the requirements.
I have designed material storage tanks with a DN3000 size, which are at atmospheric pressure; the high density of the medium requires an increased thickness of the tank shell.
Analyze each specific issue individually. Silos are different from tanks used to hold gases and liquids; the higher bulk density will definitely affect the thickness.
For that silo, since the medium is industrial salt, does it need to take accident conditions into consideration?
Design calculations shall be carried out under the most stringent conditions.
