Design of geotechnical engineering problems that involve j H( &oV
dynamic loading of soils and soil–structure interaction DTPay1]6
systems requires the determination of two important wcwQj Hwd
parameters, the shear modulus and the damping A1Ka(3"
of the soils. The recent developments in the numerical {wcO[bN
analyses for the nonlinear dynamic responses of grounds "t=UX

due to strong earthquake motions have increased the juH wHt
