Design of geotechnical engineering problems that involve DV(^h$1_
dynamic loading of soils and soil–structure interaction j`Xe0U<
systems requires the determination of two important A3C#w J
parameters, the shear modulus and the damping ZCZY gf@
of the soils. The recent developments in the numerical n

analyses for the nonlinear dynamic responses of grounds 9:!<=r k
due to strong earthquake motions have increased the !dVth)UV
demand for the dynamic soil properties corresponding OE(Z)|LF
to large strain level also. Further, the most common cause

of ground failure during earthquakes is the liquefaction D<zgs2Ex
phenomenon which has produced severe damage all (q!tI* }
over the world. This paper summarizes the methods of 3rEBG0cf]

A simple procedure of obtaining the dynamic properties FbVdqO
