Background and Purpose
The UC Berkeley - CUREE Symposium in Honor of Ray Clough and Joseph Penzien was the occasion for recognizing the notable contributions made by two of the most influential researchers and educators in earthquake engineering.
The symposium featured a technical program that was of broad appeal to engineers in practice and academia. It combined historical perspectives with state-of-the art discussions by prominent experts on topics deriving from the seminal works of Professors Clough and Penzien. Social functions provided opportunities for young engineers and long-time friends alike to meet with these prominent figures in the fields of structural and earthquake engineering.
Ray Clough, professor emeritus of structural engineering at UC Berkeley, has made major contributions in computational structural mechanics, earthquake engineering, and dynamic experimentation of structures. In 1960, Clough coined the term “Finite Element Method.” His co-development of the method stemmed back to 1953 in research he conducted with engineers at Boeing. He was an early visionary of the capability of increasingly powerful computers in conducting structural analyses that would have been impossible only a few years before.
A director of UC Berkeley’s Earthquake Engineering Research Center in the 1970s, Professor Clough earned election to the National Academies of Engineering and Sciences. He received the National Medal of Science from the President of the United States in 1994.
Joseph Penzien served 35 years as a professor of structural engineering at UC Berkeley, “retiring” as a professor emeritus in 1988 to take up a busy career as Senior Principal of International Civil Engineering Consultants of Berkeley, California. Founding Director in 1968 of the UCB Earthquake Engineering Research Center, Penzien co-authored with Ray Clough the classic textbook, Dynamics of Structures.
Like his colleague, Penzien received his doctoral degree from MIT, obtained aeronautical structural analysis experience in the early 1950s, and is a member of the National Academy of Engineering. Dr. Penzien has had extensive design and seismic criteria consulting experience in the USA, Japan, Taiwan, and Korea for major transportation system projects.
