Design of geotechnical engineering problems that involve 6i%)'dl
dynamic loading of soils and soil–structure interaction Kxg09\5i
systems requires the determination of two important WVVqH_
parameters, the shear modulus and the damping MxY CMe4S[
of the soils. The recent developments in the numerical P _9O8"W
analyses for the nonlinear dynamic responses of grounds 0F"xU1z,
due to strong earthquake motions have increased the Gc>\L3u
demand for the dynamic soil properties corresponding _\[Zr.y
to large strain level also. Further, the most common cause d(tq;2-
of ground failure during earthquakes is the liquefaction qhogcAvE
phenomenon which has produced severe damage all 9T\:ID= h
