Design of geotechnical engineering problems that involve n[0u&m8
dynamic loading of soils and soil–structure interaction xgMh@@e
systems requires the determination of two important l#enbQ`-~
parameters, the shear modulus and the damping |hxiARr4
of the soils. The recent developments in the numerical U Buh '?j
analyses for the nonlinear dynamic responses of grounds lXTE#,XVf
due to strong earthquake motions have increased the i<F7/p "-
demand for the dynamic soil properties corresponding eM nK@ J
to large strain level also. Further, the most common cause mP\V.^
of ground failure during earthquakes is the liquefaction QNOdt 2NN
phenomenon which has produced severe damage all jbipNgxkr
over the world. This paper summarizes the methods of 8)bR\s
determining the dynamic properties as well as potential B?i # m^S
for liquefaction of soils. Parameters affecting the dynamic W faMu|
