Design of geotechnical engineering problems that involve 5L c@=,/0
dynamic loading of soils and soil–structure interaction SOR\oZ7
systems requires the determination of two important ,Sgo_bC/|
parameters, the shear modulus and the damping F\N0<o
of the soils. The recent developments in the numerical =7+%31
analyses for the nonlinear dynamic responses of grounds 7#C$}1XJ1
due to strong earthquake motions have increased the K uwh A-IL
demand for the dynamic soil properties corresponding :Ob4WU
to large strain level also. Further, the most common cause :-d#kU
of ground failure during earthquakes is the liquefaction o?}d HTk7
phenomenon which has produced severe damage all qR

determining the dynamic properties as well as potential bQ>wyA+G&E
for liquefaction of soils. Parameters affecting the dynamic p?$N[-W 6-
