Design of geotechnical engineering problems that involve 1) K<x
dynamic loading of soils and soil–structure interaction ] Tb?z&
systems requires the determination of two important qLN\>Z,3;
parameters, the shear modulus and the damping L-)ZjXzk
of the soils. The recent developments in the numerical +,,dsL
analyses for the nonlinear dynamic responses of grounds EcX7wrl9x
due to strong earthquake motions have increased the xOPQ~J|z
demand for the dynamic soil properties corresponding 34X]b[^
to large strain level also. Further, the most common cause cLp_\ \
of ground failure during earthquakes is the liquefaction jygUf|

determining the dynamic properties as well as potential t\LE\[XM>
for liquefaction of soils. Parameters affecting the dynamic %TR J

A simple procedure of obtaining the dynamic properties C$ K?4$
