Stress verification at the support of horizontal containers
Thread Content
It is a horizontal, atmospheric-pressure vessel with dimensions of 3000X7400, placed on 7 concrete foundations. May I ask how the stresses at the supports should be checked?

My question is: since the diameter of the cylinder is only 7400, why are 7 supports needed? And how can these 7 supports ensure that the loads are applied almost simultaneously? How to account for uneven settlement of the foundation? If the forces are uneven, the local stresses in the cylinder will be higher.
Why are 7 concrete supports used? Regular calculations don’t have such a calculation model, right! For all 3 saddles, the height differences in installation, uneven settlement, and foundation irregularities must be taken into account. Where is it used?
Foundation settlement is a very troublesome issue. Try to avoid statically indeterminate structures.
The 7 supports can definitely be placed on a single base, which means that there is almost no difference in settlement among them
