When calculating RC. tank's cracking width, should the seismic forces be considered?

When calculating RC. tank's cracking width, should the seismic forces be considered? Can you give the direct basis on codes(USA codes, or British codes, or Eurocodes)?
I think seismic force should not be included in the load combination when calculating cracking width of tank, but I can not find the direct basis. Please help me, thank you!

Agreed.. You may look to Eurocode 2 — Design of concrete structures Part 3: Liquid retaining and containment structures . Although it is not explicitly stated , it is sufficient to check for cracking with quasi-permanent loading and my understanding is characteristic loading ( not ultimate )..
