Damping coefficients for ground types (seismic engineering)
Damping coefficients for ground types (seismic engineering)
(OP)
Can anyone explain to me/point me in the direction of some good resources on damping coefficients for different ground types?
I know the waves propegate differently through different material & if you are on a soft ground your loading will be more severe than if you were on rock...and that say if you are on a hill the loading will be more onorous but i'm not sure how to calculate the effect of any of these aspects!
Any help would be appreciated!

Anyway...If it's for concepts and the math, because I have it handy, I use "Soil Dynamics" by Tien Hsing Wu, originally published by Allyn and Bacon in 1971, then self-published in 1975. Not sure how easy it is to find. I haven't read it, but you might try Steven Kramer's book on earthquake engineering of dams, which probably has good info on response analysis, which would have include strain-dependent damping, modulus reduction, and all that stuff; and a dam is kind of like a hill.
The hill will quite likely require a 2-D analysis (QUAD4M, QUAKE/w, FLAC, PLAXIS), not 1-D (SHAKE).
