From October 5 to 11, the 16th Russian National Conference on Earthquake-Resistant Construction and Seismic Zoning was held in Sochi. The conference addressed such topical issues as seismic design standards in different countries, seismic protection, software calculations, and more. The earthquake that occurred in Kamchatka on July 30 became a high-profile topic. Experts discussed the results of seismic stations during the earthquake, the minute-by-minute occurrence of events, and concluded that the seismic event had been successfully managed.
The conference was attended by scientists and engineers from across Russia, as well as from Pakistan, India, New Zealand, Iran, Nepal, Belarus, Kyrgyzstan, Uzbekistan, and Kazakhstan. SPbGASU was represented by faculty from the Faculty of Civil Engineering.
Nadezhda Ostrovskaya, PhD, Associate Professor of the Structural Mechanics Department, spoke at the "Seismic Isolation and Other Innovative Systems and Technologies for Seismic Protection" session, where she discussed the design and calculation methods for plastic dampers. She noted the enormous scientific contribution to the development of structural mechanics made by Professor Yuri Rutman, who recently passed away: "Yuri Lazarevich was a very gifted and prolific scientist. Within the walls of SPbGASU, he nurtured more than ten PhD candidates and specialists in earthquake engineering. He established a scientific school on seismic isolation, specifically plastic dampers of various configurations, which I will strive to continue. Yuri Lazarevich's contribution cannot be overestimated." The presentation was dedicated to the publication of the monograph "Plastic Dampers: Design, Calculation, Experiment" in 2025.
Olga Nesterova, PhD, Associate Professor of the Department of Structural Mechanics, presented a paper at the "Application of CAD and Computational Modeling in the Design of Buildings and Structures" section on the consideration of vibration mode correlation in seismic impact analysis. "As part of my research on dynamic vibration dampers for seismic protection of buildings and structures, I discussed an important factor that must be considered in earthquake impact analysis: vibration mode correlation. This is the influence of vibration modes on each other, and failure to consider this can lead to incorrect conclusions when assessing the seismic resistance of buildings and structures." The main conclusion of the study was that there are a number of structures for which consideration of correlation is essential in the analysis. It was proposed to introduce recommendations on how to consider correlation into standards.
Professor Sergey Savin, Doctor of Engineering, Department of Reinforced Concrete and Masonry Structures at St. Petersburg State University of Architecture and Civil Engineering, moderated the section "New Design Solutions, Reinforced Concrete, Metal, and Steel Structures. Design, Construction, and Design of Earthquake-Resistant Buildings and Structures, Earthquake-Resistant High-Rise Buildings. Features, Problems, and Challenges of Safe Design and Construction." He also presented his own paper on "Verification of Design Models for Large-Span Shell Roofs Based on Their Dynamic Parameters Determined During Free-Vibration Testing." Sergey Nikolaevich focused on the A.P. Chekhov Sakhalin International Theatre Center, located in the earthquake-prone city of Yuzhno-Sakhalinsk. During the discussion, the experts concluded that this method is highly effective.
This section also featured Sergey Tetushkin, an assistant professor in the Department of Structural Mechanics, who presented a paper on "Improving the Analytical Method for Calculating the First Mode of Natural Vibrations of Building Structures Using a Correction Factor." In his paper, Sergey shared some experimental and theoretical results from studies of a cantilever model of building structures with five concentrated masses, which, according to the regulatory document SP 14.13330.2018, is required for seismic impact analysis. These studies were conducted jointly with the Center for Integrated Seismic Testing.
Another participant in this section affiliated with our university was Sergei Mikhailenko, a graduate of the Leningrad Civil Engineering Institute (LISI, now SPbGASU), who presented a paper titled "Design of Facade and Window Structures." He shared his experience using translucent structures in Canada and presented SPbGASU representatives with his monograph, "The Practice of Constructing Translucent Facades and Other Glass Building Structures Based on Experience in North America."
At the "Fire Safety of Buildings and Structures. Seismic and Fire Safety of Building Structures and Materials" section, Don State Technical University Professor Lyubov Morgun, in her report "Foam Concrete for Improving the Seismic and Fire Safety of Buildings," paid tribute to "outstanding LISI scientist" Professor Igor Aleksandrovich Lobanov and presented the author's certificate "Raw Material Mix for Obtaining Cellular Concrete," obtained by I. A. Lobanov and Yu. V. Pukharenko in 1981.
Tatyana Belash, Doctor of Engineering, Advisor to the Russian Academy of Architecture and Construction Sciences, and Consulting Professor of the Department of Metal and Wood Structures at St. Petersburg State University of Civil Engineering (SPbGASU), served as one of the conference organizers. As is traditional, the conference concluded with a roundtable discussion of pressing issues related to seismic impact design standards, highlighting the undeniable relevance of the issues discussed and the importance of the results obtained through the research presented at the event.
