There is a need to determine the dynamic properties of soil in order to be able to do accurate numerical modelling of the response of soil to earthquake loading. The response of soil to dynamic loading is generally defined by one dimensional analyzes therefore shear modulus and damping ratio properties of soil are required. Even though there are curves in  the  literature  defined  by  various  researchers  for  the  relationship  between  dynamic  properties of soil and shear strain it would be more accurate and ideal if we use curves  which represents real site conditions. In this study it is aimed to determine the dynamic  properties of a large scale engineering fill by series of cyclic simple shear experiment in the  laboratory. In accordance with this purpose samples obtained by drilling from construction  site  of  an  embankment  were  used.  In  the  laboratory  constant  volume  controlled  cyclic  simple  shear  tests  were  conducted  on  these  samples  for  various  cyclic  stress  ratios  (CSR= τ/σv’) in order  to determine  the effect of plasticity index on  relationship between  dynamic properties and shear strain to be used in seismic response analysis.   Keywords: Compacted Soil, Dynamic Simple Shear, Shear Modulus, Damping Ratio
