Design of geotechnical engineering problems that involve ST KL
dynamic loading of soils and soil–structure interaction NvK9L.K
systems requires the determination of two important K<JzIuf&
parameters, the shear modulus and the damping uvys>]+
of the soils. The recent developments in the numerical 7ZcF0h

due to strong earthquake motions have increased the 1 ZdB6U0

to large strain level also. Further, the most common cause WQ|:TLQ
of ground failure during earthquakes is the liquefaction ]a3$hAcj6"
