National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Soil Moduli and Damping Factors for Dynamic Response Analyses.

PB197869

Publication Date	1970
Personal Author	Seed, H. B.; Idriss, I. M.
Page Count	48
Abstract	The report summarizes the available data concerning the shear moduli and damping ratios for soils. Clearly more data on these dynamic characteristics is required, particularly for silts, clays and gravelly soils. However it is hoped that the data presented will serve as a useful guide in the selection of soil properties for dynamic response analyses and that other engineers might be encouraged to make available any additional data which would supplement that presented above.
