Hydrodynamic on Buried Tanks

[Lily_Linton]

Hello fellow engineers,

ACI 350.3 shows how to compute and how to load dynamic analysis for liquid containing structures. I am curious when are we not gonna use this kind of code in a buried structure? Is there a minimum depth that we need to consider?

Thanks to all that will answer this

In a buried structure, I would assume it would be used where water is flowing through a culvert and it changes directions (flow goes around a corner).

Having not seen that spec., I would guess the main area of applicability would be be to calculate wave forces on seawalls and the like.

Check chapter 15 of ASCE 7. If a project is to be done in accordance with ASCE 7, the provisions in that chapter will govern when and how hydrodynamic loads in tanks and similar structures are considered in design. I don’t remember if there is any specific minimum liquid level in either document that allows you to ignore hydrodynamic effects altogether. It’s a good question.
