Design of geotechnical engineering problems that involve X&cm)o%5Fe
dynamic loading of soils and soil–structure interaction '" J``=
systems requires the determination of two important RV_+-m{]
parameters, the shear modulus and the damping 9NausE40
of the soils. The recent developments in the numerical =J^FV_1rJ
analyses for the nonlinear dynamic responses of grounds v42Z&PO
due to strong earthquake motions have increased the ]xN )>A2
demand for the dynamic soil properties corresponding |/O_AnGI
to large strain level also. Further, the most common cause U t .#h="
of ground failure during earthquakes is the liquefaction 9M1 UkS$`@
phenomenon which has produced severe damage all zAO|{m<A2

determining the dynamic properties as well as potential ++Fk8R/$U[
for liquefaction of soils. Parameters affecting the dynamic nx@ h
