Freboard for sloshing liquid in API 650 tanks 1

[JoseAcevedo]

Does anyone can tell me the criteria to evaluate if the tank roof and shell are designed to contain the sloshing liquid?

By the other hand I would like to know what happen if the sloshing height is bigger that the freeboard.

Jose,

It sounds like you are doing some kind of seismic evaluation of an existing tank....is that true ?

There was some work done for nuclear power plants on the seismic effects of condensate storage tanks (API-650 like design) during a seismic event. Quantification of the sloshing is a big issue. People have written thesis abount this specifc topic using Finite Element Analysis (FEA) to verify thier models and assumptions

I beleive that the USNRC published a guidleine, under an ASCE title. (
