Design of geotechnical engineering problems that involve /s+IstW
dynamic loading of soils and soil–structure interaction g]N'6La
systems requires the determination of two important RL\?i~'KH
parameters, the shear modulus and the damping VpB)5>
of the soils. The recent developments in the numerical n'q:L(`M
analyses for the nonlinear dynamic responses of grounds Z]tQm V8 e
due to strong earthquake motions have increased the SO STtuT
demand for the dynamic soil properties corresponding X@:Y. /
to large strain level also. Further, the most common cause -F*vN'
of ground failure during earthquakes is the liquefaction ,~1sZ`C
phenomenon which has produced severe damage all _!vy|,w@e
