I work in a company as an engineer and we manufacture and assemble tanks to store drinking water.
I made a design of a tank with the diam. 11.45 m and 10.50 m in height.
My question is with regard to the minimal design thicknesses.
Should I adopt 6.4 mm for the minimum thickness of bottom plate, considering that the civil base is in concrete?
I must adopt 4.8 mm for the minimum thickness for the cylindrical part of the tank or 6.4 mm
