Design of geotechnical engineering problems that involve D0\*WK $
dynamic loading of soils and soil–structure interaction [)} `w;#
systems requires the determination of two important =WF @S1
parameters, the shear modulus and the damping `?&C5*P
of the soils. The recent developments in the numerical QBmARQ
analyses for the nonlinear dynamic responses of grounds aIT0t0.
due to strong earthquake motions have increased the LB7 $&.m'B
demand for the dynamic soil properties corresponding hRKJKQ@7
to large strain level also. Further, the most common cause CZy!nR!
of ground failure during earthquakes is the liquefaction Q_/UC#I 8
phenomenon which has produced severe damage all u YFy4E3
over the world. This paper summarizes the methods of JWu0VLo
determining the dynamic properties as well as potential 9XUYy2{G
for liquefaction of soils. Parameters affecting the dynamic .4 NcaMj
