- Abstract
- The forms of the relationships expressing shear modulus and damping ratio as a function of shear strain play an important role in determining the results of ground response analyses. The report summarizes available data on the dynamic shear moduli and damping factors for cohesive soils under cyclic loading conditions and presents the results in a form which will provide a useful guide in the selection of soil characteristics for analysis purposes. Emphasis is placed mostly on clays, though limited data for offshore samples and mudstone are also included.
