Does anyone know how to calculate the middle skirt?

Is this structure easy to use? Isn't there a leveling problem between the middle support and the bottom support? To actually build this kind of structure, conventional calculations would be impossible, and stress analysis would be difficult to do. Even if it is actually used, there should be problems.
This structural rule design is difficult to calculate as wind and seismic loads are difficult to load. Why not use a circle seat? Equipment as tall and heavy as the silo uses ring seats.
Since wind and seismic loads are difficult to load, this structural rule design is difficult to calculate. To accurately calculate, only analytical design can be used, which requires coupling seismic and wind loads. However, the corner joint is not easy to evaluate during stress evaluation. Why not use a circle seat? Equipment as tall and heavy as the silo uses ring seats.
I usually use vertical ear mounts to calculate
What we are doing is a tube-wound heat exchanger with a relatively large flow rate, and then we use the middle skirt structure shown in the picture above, but we don’t know what algorithms there are.
Best stress analysis is recommended. There are really no conditions, so follow the following ideas: In PVELITE, the algorithm of the middle skirt can be established, and then the retaining ring welds can be checked (subject to wind, earthquake bending moment and gravity). The thickness of the small side at the lower end of the retaining ring should be greater than the height of the weld.
It is often used in engineering that this is a static-indeterminate problem, and adding a support is definitely better than not adding one. feasible.
Is this not called the middle skirt seat? The middle skirt refers to the tube section between the heads of two or more pressure chambers.
How to check the retaining ring welds? Is there any corresponding calculation formula or table? If you want to add QQ, I will ask you for advice 615904051
There is a ring seat in the middle and a skirt seat at the bottom, right?
