Thank you @HTURKAK on your response. The tank capacity is around 95,000 m3 which is quite big, and the site is located in Middle East. The proposal we have in mind is rectangular concrete storage tank. Do you know any code helpful on the design of storage tank other than ACI 350?
Looking at UL...
We are studying to design an underground tank for storage of products like gasoline, diesel, jet-oil, etc. I know that good information on the subsurface conditions across the site will be needed. Our current proposal is having a concrete tank, but I wanted to check if someone has any experience...
