Design of geotechnical engineering problems that involve I$ )9T^Ra
dynamic loading of soils and soil–structure interaction TaKHr$h
systems requires the determination of two important SrOv*

parameters, the shear modulus and the damping d{(Rs.GuP
of the soils. The recent developments in the numerical 6W7,EIf
