This report summarizes available data on the dynamic shear moduli and damping factors for cohesive soils under cyclic loading conditions and presents results in a form which will provide a useful guide in the selection of soil characteristics for analysis purposes. Emphasis will be placed mostly on clays, though limited data for offshore samples and mudstone are also included.
