API standard 650 flat-bottom oil storage tanks impulsive spectral acceleration parameter
The thickness of the API standard 650 flat-bottom oil storage tanks annular bottom plates shall be in accordance with Table Q-4 (for steel or aluminum, as applicable). The thicknesses shown are minimums. The ring of annual plates shall have a circular outside circumference, but it may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates.
