Dear Mariog,

Thank you so much for your help.
Conflicts that I thought were the subjects that you declared. I did not realize the definition in 13.1.2.

By the way.I have still some questions regarding the subject; I would like to understand that;

In AWWA / 3.8.9.1 Anchors;
It says; ....When the calculated net uplift force for both PW and PS results in a negative value,no uplift anchorage is required. For single-pedestal and ground-supported flat bottom tanks, the design uplift forces PW and PS are....
That means.
in negative value --> anchorage is not required.
in positive value --> anchorage is required.
Is it right?
If the J-overturning ratio is above 1,54. We have to check this section and calculate tension forces for anchors.If the j is below 1,54. then do we have to check this section. In API650, this formula is valid only if the anchors are required.


What if we do not provide 5 stability conditions?(In achorage section , E6.2.1) for instance 0,035D limitation. What is the meaning of 0,035D in theory. What is the importance of it? Is it a result of a mathematical model or experimental result.

Thank you so much for your help!
