Design of geotechnical engineering problems that involve 'cNKjL;
dynamic loading of soils and soil–structure interaction $T<}y_nHl
systems requires the determination of two important T@%m 7 |P
parameters, the shear modulus and the damping e4I^!5)N
of the soils. The recent developments in the numerical O:#+ %
analyses for the nonlinear dynamic responses of grounds y<XlRTy[}
due to strong earthquake motions have increased the ~|wos-nM
demand for the dynamic soil properties corresponding `o79g"kxe
to large strain level also. Further, the most common cause XJ!(F#zc
of ground failure during earthquakes is the liquefaction iqhOi|!
phenomenon which has produced severe damage all :Vg}V"QR

for liquefaction of soils. Parameters affecting the dynamic _ nP;Fx
properties and liquefaction have been brought out. !3oKmL5
A simple procedure of obtaining the dynamic properties Wk^RA _
