What Liquefaction Screening Assessment Methods Are People Using?
(OP)
Just trying to get an idea of what the industry is using at the moment.

Going to order the EERI book as a personal Christmas gift to myself

You don't have to worry about whether they are the right size for the recipient.
You don't have to worry about whether they like the color, or whether it goes properly with their decor or their other clothing.
Nobody ever says "Ohhh, I already have a bottle of wine. I don't want another one." (This is somewhat of a risk with a book, however, except when giving it to yourself.)
You don't have to worry about them going out of fashion soon, unlike neckties and purses.
If you put one on the shelf and forget about it for a few years, you may come back, open it up, and find that it is full of some very good stuff you had forgotten about.

Yes I mean the EERI book.
For the most part the book is just a summary of previous papers on the subject.
I do have several issues with it regarding sections on calculating CSR i.e. recommendations for using site specific dynamic response analyses for deep profiles with no discussion regarding the methods used by B&I to calculate the CSRs used in their CSR CRR relationships.
And the treatment of fines corrections for CPTs I think is bit haphazard and doesnt take into account the significant effect of compressibility especially with silty angular soils (i.e. tailings).
Mccoy,
I just bought Zienkiewics' et al. book on Computational Geomechanics for myself for christmas. Hell of a read. Lucky I live in Canada where there is nothing better to do in winter.

Interestingly, for residual undrained shear strengths from CPT, Olson and Stark's data show practically no effect of fines at all. There may be different mechanisms involved, however. One of the more important dots on the plots is Mochi-Koshi gold tailings. Wonder how compressibility might have affected that.
To the best of my knowledge, they used Idriss's magnitude-dependent Cn (1999?) to get the CSRs to develop the triggering curves.
