He was born February 6, , in Kiev, then part of the Russian Empire. He and his family escaped to Manchuria in during the Bolshevik Revolution, and from there went to Shanghai before emigrating to the United States in His family settled in San Francisco, and in Popov entered the University of California, Berkeley, where he studied civil engineering and graduated with honors in He received a scholarship for graduate studies at the Massachusetts Institute of Technology and obtained his MS degree in civil engineering in He was then awarded a scholarship to the California Institute of Technology and moved to Pasadena to pursue his doctoral degree.
He was advised, however, that his approach to engineering was more mathematical than practical and that he would be better suited to study under Stephen Timoshenko at Stanford University. He left Caltech and worked for eight years in southern California, doing structural analysis and design for numerous public and private concerns. Memorial Tributes: Volume Using the latter credentials, he constructed his own house in San Gabriel. In he contacted Timoshenko and explained that he wanted to pursue a dissertation in civil engineering.
The Stanford faculty accepted his graduate course work at MIT and Caltech as sufficient, and Popov immediately began work on his dissertation under Timoshenko. He received his PhD degree in civil engineering and applied mechanics in the summer of and was offered and accepted a position as assistant professor at UC Berkeley. Popov was instrumental in establishing a PhD program in civil engineering at Berkeley. Mihran Agbabian was the first PhD graduate in civil structural engineering in and founded his own consulting engineering company and become chair of civil engineering at the University of Southern California.
Popov was promoted to professor in and mentored 34 PhD students during his tenure at UC Berkeley. In his early efforts developing engineering course material, Popov perceived that available textbooks were not sufficient in engineering mechanics, so he wrote and published Mechanics of Materials Prentice Hall in It was adopted as an engineering textbook at many universities in the United States and was translated into several languages for use in foreign engineering programs.
A second edition was published in Burgeoning interest in structural mechanics education prompted the Civil Engineering Department at UC Berkeley to create a new division in for structural engineering and structural mechanics, of which Popov was the first chair.
He was also the director of the Structural Engineering Laboratories in the Civil Engineering Department, indicating his interest in evaluating theoretical results using test structures. He developed theoretical methods to predict the behavior of shell structures, particularly for buckling failures, and these methods led to advances in the design and construction of water storage tanks and airplane hangars.
His work on shell buckling prompted the National Aeronautics and Space Administration to ask him to resolve buckling problems related to its large ft tall, 60 ft diameter vacuum chamber in Houston in the s. The chamber was designed to mimic conditions expected during a moon landing and to test equipment that would be used in that effort.
At the time, finite element solutions were not available for three-dimensional curved structures, but Popov achieved a solution using a finite element analysis for a flat surface with ribs and calculating the equivalent forces for a curved surface with ribs. NASA implemented the solution and the vacuum chamber performed as required. He also published numerous technical papers on nonlinear mechanics and constitutive properties. Popov continued applied research on nonlinear response of structures, initially studying the cyclic, nonlinear behavior of reinforced concrete structural members and systems, and then steel structural members and systems.
For the latter he conducted experiments and analyzed the connections of steel beams and columns, both welded and bolted. He also developed methods to use friction devices to retrofit existing structures, thereby increasing their seismic safety. His methods to avoid structural failures were adopted in the design of the Alaska pipeline and the San Francisco—Oakland Bay Bridge.
The American Iron and Steel Institute supported much of his research and published his results in its Bulletins. Popov was one of the few faculty members at UC Berkeley who was a registered structural engineer in California in addition to being a registered civil engineer and mechanical engineer.
Through these contacts, Popov developed an interest in analyzing and testing eccentrically braced frames EBFs and applied that knowledge to evaluate and improve the seismic design of numerous structures. He recognized that EBFs had been used for many years in structures to provide lateral resistance to wind loads, but those applications required the braces to perform elastically.
The use of EBFs to resist lateral loads from earthquake shaking was first investigated by Popov and Charles Roeder, one of his PhD students, in the s. They recognized that EBFs had an advantage over other methods of lateral-load resistance by both absorbing energy through inelastic response and reducing nonstructural damage by limiting interstory displacements. One was that testing specimens using numerous low-strain nonlinear tests did not give good predictability of structural behavior during large-strain, limited cycle motions.
Another was that large-scale, not just small-scale, specimens needed to be tested in the laboratory. A third was that steel beam-column assemblages need to be joined with full-penetration welds. These lessons provided insights into how real structures perform when subjected to high loading conditions inducing large strains, conditions that were not well understood.
Popov participated in a joint US-Japan research effort, with US funding from the National Science Foundation, in which full-scale testing was conducted at a test laboratory in the Japanese city of Tsukuba. There, a full-scale EBF connection was constructed where the brace was attached to the beam using a welded T-connector. Popov predicted that the web of the T-connector would fail under compression and thus would be the weak link in the EBF.
Popov retired from UC Berkeley in and was subsequently recognized with the title Professor of the Graduate School, which allowed him to continue research with funding from the university. He studied methods to improve the behavior of steel and reinforced concrete structures during earthquakes, using improved design of both structural connections by welding and high-strength bolts for steel structures, and details of steel reinforcing for concrete structures and structural bracing.
He published his third book, Engineering Mechanics of Solids, in , with a 2nd edition in both published by Prentice Hall. Popov in — while a graduate student in the SESM Department at UC Berkeley, and was impressed with his friendly, caring approach toward all graduate students, even those not studying under him.
All who knew Egor Popov remarked on his strong marriage with Irene, whom he met in Los Angeles and married in Irene provided personal support as well as secretarial services for Egor, typing his manuscripts for books and papers. Egor and Irene Popov raised two successful children, Kathy and Alex. Irene passed away in Popov was survived by a brother, Nicholas Popov of Santa Rosa, California recently deceased ; daughter Katherine Crabtree of Medford, Oregon; son Alexander Popov of Anna, Illinois; six grandchildren; and eleven great-grandchildren there are now 16 great-grandchildren.
