The John A. Blume Earthquake Engineering Center was established to promote research and education in earthquake engineering. Through its activities our understanding of earthquakes and their effects on mankind’s facilities and structures is improving. The Center conducts research, provides instruction, publishes reports and articles, conducts seminar and conferences, and provides financial support for students. The Center is named for Dr. John A. Blume, a well-known consulting engineer and Stanford alumnus. Address: The John A.

ACKNOWLEDGMENTS
This report was originally published as the Ph.D. dissertation of the first author.
The authors wish to acknowledge the following: Luis Esteva supplied building
code information, subsurface investigation reports, and, most importantly,
facilitated our access to the Pino Suarez complex. Damage survey and technical
data on the office building at 77 Amsterdam Street were provided by Enrique
Martinez-Romero. The comments and observations of Oscar de Buen's office
regarding Pino Suarez were most helpful. Eduardo Miranda's first hand accounts of
building damage and assistance with building identification is greatly
appreciated. Hiroyuki Fuyama translated portions of the report prepared by the
Japanese reconnaissance teams, which made this excellent reference accessible.
The study upon which this dissertation is based was supported, in part, by the
National Science Foundation through the Grant ECE-8611054. The generous
support provided by the Northern California Chapter of the Achievement Rewards
for Col1age Scientists (ARCS) Foundation is greatly appreciated.
