Design of geotechnical engineering problems that involve h 8e757z
dynamic loading of soils and soil–structure interaction >vbY<HGt
systems requires the determination of two important :G5uocVk
parameters, the shear modulus and the damping o@bNpflb`
of the soils. The recent developments in the numerical ^ |MjJsn
analyses for the nonlinear dynamic responses of grounds 3)=c]@N0
due to strong earthquake motions have increased the x_#-tB
demand for the dynamic soil properties corresponding fbvbz3N
to large strain level also. Further, the most common cause 9uk<&nqx
of ground failure during earthquakes is the liquefaction @Xp~2@I=ls
phenomenon which has produced severe damage all \]4v _!
over the world. This paper summarizes the methods of ;]s Yf
determining the dynamic properties as well as potential *QGm/ /b
for liquefaction of soils. Parameters affecting the dynamic ` `U^COD
properties and liquefaction have been brought out. Jc6R{C
A simple procedure of obtaining the dynamic properties m Lk(y*
of layered ground has been highlighted. Results of a ?.=}pAub
