Depending on the tank design,the bottom plate may be thinner,thicker,or the same as the first shell course.But see the limitations in E.6.2.1.1.3.Usually,an annular plate is same thickness as the rest of the bottom,or thicker.I've never seen an annular plate thinner than the remainder of the bottom.
