Design of geotechnical engineering problems that involve yuEOQ\!(u
dynamic loading of soils and soil–structure interaction GK?R76d
systems requires the determination of two important tY'QQN||
parameters, the shear modulus and the damping P1 stL,
of the soils. The recent developments in the numerical mX@* 2I
analyses for the nonlinear dynamic responses of grounds K- C-+RB
due to strong earthquake motions have increased the I?Fa
demand for the dynamic soil properties corresponding f*{;\n (.t
to large strain level also. Further, the most common cause )O C[;>F7
