Design of geotechnical engineering problems that involve #}nDX4jI
dynamic loading of soils and soil–structure interaction j: J7
systems requires the determination of two important Wg=4 `&F^
parameters, the shear modulus and the damping Ec eD\ }
of the soils. The recent developments in the numerical KA]5tVQA
analyses for the nonlinear dynamic responses of grounds bqm%@*fZo
due to strong earthquake motions have increased the :stA]JB#
