Design of geotechnical engineering problems that involve !GVxQll[f
dynamic loading of soils and soil–structure interaction h'G8@j;
systems requires the determination of two important Yy0m &3[
parameters, the shear modulus and the damping cV )~%e/
of the soils. The recent developments in the numerical Z7R+'OC
analyses for the nonlinear dynamic responses of grounds YyR~pT#ffT
