Design of geotechnical engineering problems that involve x$BNFb%I1
dynamic loading of soils and soil–structure interaction h^tCF =S
systems requires the determination of two important Zc1x"j
parameters, the shear modulus and the damping ]& Y^
of the soils. The recent developments in the numerical %wOkp`1-
analyses for the nonlinear dynamic responses of grounds 5{V"!M+<
due to strong earthquake motions have increased the HFy9b|pjy
demand for the dynamic soil properties corresponding Nv36#^Z
to large strain level also. Further, the most common cause TMPk)N1Ka
of ground failure during earthquakes is the liquefaction
