Design of geotechnical engineering problems that involve L.>`;`dmY
dynamic loading of soils and soil–structure interaction fxjs "rD5
systems requires the determination of two important g^=p)h3
parameters, the shear modulus and the damping [^#6.xH
of the soils. The recent developments in the numerical Sw Lul4V
analyses for the nonlinear dynamic responses of grounds KATt 9ox @
due to strong earthquake motions have increased the _Y=>^K]9K
demand for the dynamic soil properties corresponding geua8;
to large strain level also. Further, the most common cause 66 v6do7
of ground failure during earthquakes is the liquefaction ~h -0rE
phenomenon which has produced severe damage all @Kp2l<P

determining the dynamic properties as well as potential < f1 Pj
for liquefaction of soils. Parameters affecting the dynamic k\A8Z[
properties and liquefaction have been brought out. h60*=+vdJ
A simple procedure of obtaining the dynamic properties t
