Dear Users,

firstly, I kindly ask the forum operator's permission. I know that Intergraph-Tank software can be used for the API related tank design. But,The users,the tank designers might have an experiences regarding AWWA D100 tank design.

My question is about the anchorage requirements in AWWA D100.
You know. In API 650 , Appendix E , we use overturning ratio formula for determining the anchorage is needed or not.
The same criteria is valid for the AWWA D100-05. (Eq 13-36)
But there is a conflict in Section 3.8.9.1, According to the Eq 3-41, you determine the anchorage needs. when we compare the results of Eq 13-36 and Eq 3-41, we come across with a conflict.

If anybody have a comment regarding anchorage in AWWA D100, I would be waiting your answers.

thanks in advance.
