Design of geotechnical engineering problems that involve RU7!U mf
dynamic loading of soils and soil–structure interaction J,9%%S8/C
systems requires the determination of two important ;|;iCaD a+
parameters, the shear modulus and the damping 1b8c67j[
of the soils. The recent developments in the numerical wz h. $?~
analyses for the nonlinear dynamic responses of grounds fwy"w
due to strong earthquake motions have increased the ;KL9oV!<f
demand for the dynamic soil properties corresponding \<=IMa0
