Design of geotechnical engineering problems that involve xww\L

dynamic loading of soils and soil–structure interaction d%oHc n
systems requires the determination of two important (AHTv8
parameters, the shear modulus and the damping jjg&C9w T
of the soils. The recent developments in the numerical zF&_9VNk=c
analyses for the nonlinear dynamic responses of grounds $ C8s
due to strong earthquake motions have increased the .iST!n h
demand for the dynamic soil properties corresponding q2M %AvR
to large strain level also. Further, the most common cause K:Z|# i-
of ground failure during earthquakes is the liquefaction zhU^~4F
phenomenon which has produced severe damage all 0p'g+ 2
