Design of geotechnical engineering problems that involve BUEV+SZ4
dynamic loading of soils and soil–structure interaction J)=Ts({
systems requires the determination of two important "eKM<S
parameters, the shear modulus and the damping 'jU ;.vZex
of the soils. The recent developments in the numerical B+=Xb;p8
analyses for the nonlinear dynamic responses of grounds N*>&XJ#
