When designing storage tanks in accordance with GB50341-2014, wind stability analysis revealed that some of the tanks designed originally require anchoring

When designing storage tanks in accordance with GB50341-2014, wind stability calculations show that some tanks designed under the previous standard 50341-2003 require anchoring. If anchoring is necessary, must the foundation of such tanks be a rigid foundation? Do experts design storage tanks in accordance with GB50341-2014 these days? Experts, please reply
I’m also learning how to calculate* anchor bolts; let’s encourage each other~
If the storage tank and foundation are not secured using anchors, is it possible to weld them to the channel steel instead?
I have not yet designed a structure with the base plate welded to channel steel; do you have anything similar?
Compared to the older version, the current 50341 storage tanks often require anchoring; the anchoring bolts must be embedded in the foundation, which is usually a concrete foundation. The diameter of the bolt circle should be slightly larger than that of the tank bottom plate. Additionally, the bottom plate of the tank deforms during pressure testing and use, so it cannot be welded in place. Furthermore, the welds on the tank walls and bottom plate are already fragile; it is not sufficient to secure only the bottom plate.
We also observed the situation described by the poster during our calculations, and it turns out that anchoring is required in almost all cases. The foundation uses concrete ring beams, with asphalt sand filled in the middle. Of course, the design is carried out in accordance with GB50341-2014.
During the design process, I found that in many structures, the floor slab is directly welded to the steel beams of the underground ring beam, and both the floor slab and the wall panels are reinforced using rebar. So such a design should work. Welded with channel steel.
Anchoring is required when the design criteria are not met in terms of wind resistance, internal pressure, and seismic performance calculations
