Design of geotechnical engineering problems that involve ! _] Y~[
dynamic loading of soils and soil–structure interaction oA7tE u
systems requires the determination of two important n$MO4s8)
parameters, the shear modulus and the damping O40?{v'
of the soils. The recent developments in the numerical KB3Htw%W[+
analyses for the nonlinear dynamic responses of grounds SB;&GHq"n
due to strong earthquake motions have increased the e/KDw
