Why are the edge plates of a tank generally thicker than the mid-span plates?

Why are the edge plates of the bottom plate of a dome tank generally thicker than the mid-span plates? For example, the thickness of the middle plates is 8 mm, while the thickness of the edge plates is generally around 10 mm. Why is that? Is it because the stress on the edge plates is relatively complex or high? Thank you, there is a rating for replies
That’s right; the edge plates are subject to the most complex stresses, with the fillet welds being the areas where stress is most concentrated
