I'm looking a good sample problem which determined the Seismic moment induced on a footing , I need to review a existing footing for a new tank install

Pls have a look to the followings;


-E.6.1.2.1 Center of Action for Ringwall Overturning Moment
The ringwall moment, Mrw, is the portion of the total overturning moment that acts at the base of the tank shell
perimeter. This moment is used to determine loads on a ringwall foundation, the tank anchorage forces, and to check
the longitudinal shell compression....

-E.6.1.2.2 Center of Action for Slab Overturning Moment
The “slab” moment, Ms, is the total overturning moment acting across the entire tank base cross-section. This
overturning moment is used to design slab and pile cap foundations....

- Annex EC.9 Example Problems


P.S. You may provide more detail to get better responds ..

not to wish to know is worse.

hi expert
I would like to ask a question regarding the impact test for tanks
in my condition of design the temperature is between -5 and 55 c°
the tank shell first course is 12 mm , the material grade is a283 grc
i want to confirm if the imapct test is resuired or no??because the requirment
in api 650 is not clear for me

Broline. Please don't hijack someone else thread.

Just delete your post and start a new one.

That's how it works around here.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Broline: It would not be required. This is a Group-1 material, so you can check figure 4.1a of API650, for impact test exemption.
