Design of geotechnical engineering problems that involve k< RaC=
dynamic loading of soils and soil–structure interaction @B! gxW\C
systems requires the determination of two important w8F`RRHEE
parameters, the shear modulus and the damping &Y3ZG RT
of the soils. The recent developments in the numerical %0vWyU:K9
analyses for the nonlinear dynamic responses of grounds H- eHX3c7
due to strong earthquake motions have increased the 4W=fQx]
demand for the dynamic soil properties corresponding $p*.[)
to large strain level also. Further, the most common cause M2nUY`%#v
of ground failure during earthquakes is the liquefaction -X-sykDm
phenomenon which has produced severe damage all '@ 1C$0tx
over the world. This paper summarizes the methods of )GOio+{ H
determining the dynamic properties as well as potential C%#u2C2
for liquefaction of soils. Parameters affecting the dynamic xF*i+'2
properties and liquefaction have been brought out. 8& CQx*
A simple procedure of obtaining the dynamic properties 2` Ihrz6
