The filler is supported by grid plates below; the strength of these grid plates has been calculated. As for whether additional support beams are needed, how is that determined?

I would like to ask everyone: the diameter of the packing tower is currently 2500 mm, it uses regular packing; the height of the packing is about 3 meters, and its weight is around 3 tons. The packing is supported by grid plates below it, and the strength of those grid plates has been calculated. Without considering the division of the structure into sections, is it necessary to add support beams? How should this be determined? Are there any calculation bases for the support rings and stiffening plates?
Support beams should be provided for fill towers with a diameter exceeding 2000 mm.
A support beam in the middle will do
I was wondering what standards apply to this, or where the regulations and guidelines can be found? Is it based on experience, or should block support be considered?
Yes, usually a beam is installed; is it possible to do without a support beam?

With such a large diameter, and in addition to a beam for reinforcement, there have indeed been cases where the grating panels collapsed
The calculation can proceed without the use of support beams; it’s the same principle as when calculating small-diameter tower grating plates, where no such elements are needed
A support beam should be considered during design.
