Reports

 

Digital copies of the UC Berkeley Geotechnical Research Reports dating back through the 1960s are available online through the NISEE Earthquake Engineering Online Archive, at:

The Earthquake Engineering Online Archive NISEE e-Library (berkeley.edu) The database is searchable by keywords, authors and other methods to assist in locating desired publications.

Despite the location of the repository, these research reports cover a wide range of geotechnical topics, not just earthquake related topics, and typically served to document in detail the doctoral research of students studying under Profs. H.B. Seed, J. Mitchell, M. Duncan, T. Brekke, R. Goodman, J. Lysmer, W. Houston, N. Sitar, R.B. Seed, J. Pestana, S. Glaser and others, including the current Geosystems faculty.
