Gian Michele Calvi: The Art of Seismic Design
Thursday, July 4th, MiCo Auditorium

Abstract:
At the WCEE 2004 in Vancouver, Tsuneo Katayama raised the importance of placing an appropriate balance between science and experience, or science and art, in earthquake disaster mitigation. This vision inspired this monograph, in which the evolution of the approaches for seismic design is critically revisited. In the book's first part, seismic design is reviewed, considering its objectives and then discussing the dawn of structural dynamics, the lessons learned from some earthquakes of the XX century and the development from force-based to displacement-based design. Buildings, bridges, and isolated structures are considered, in principle, applications to simple examples, facilitating comparisons and conclusions. In the second part, seismic action is considered from an engineer's point of view, summarising and simplifying the process of probabilistic seismic hazard analysis (a mystery for most engineers) to obtain sound and effective representations of spectra for design and assessment. An approach for loss–based design is then presented to minimise seismic loss, including investments and progressive costs over time. In the appendix, the hand calculations for the assessment, repair and strengthening of the Anatolian Viaduct following the 1999 Düzce earthquake are presented in detail as an example of an ante litteram application of comprehensive design principles and capacity design to the real world.

Bio:
Gian Michele Calvi is a professor at the IUSS Pavia, director of science at the Eucentre Foundation in Italy, and executive vice president of the IAEE. He graduated at the University of Pavia and received a Master of Science from the University of California, Berkeley, a PhD from the Politecnico di Milano and an Honorary Doctorate from the University of Cujo, Mendoza, Argentina. He has founded the Eucentre Foundation and the ROSE School (with M.J.N. Priestley). In 1996 he created the Journal of Earthquake Engineering (Taylor and Francis), with A.S. Elnashai and N.N. Ambraseys, where he still serves as associate editor. He is the author of hundreds of publications and of a few books, including: Seismic Design and Retrofit of Bridges (with M.J.N. Priestley and F. Seible, 1996), Displacement-Based Seismic Design of Structures (with M.J.N. Priestley and M.J. Kowalsky, 2007), Seismicdesignandanalysisoftanks (withR. Nascimbene, 2023). On the occasion of the WCEE 2024, he published a “Master Series” monograph, The Art of Seismic Design, by invitation of the IAEE President and Past President. He has been invited keynote speakers in tens of conferences, including two World and four European Conferences on Earthquake Engineering. He has been a designer, consultant or checker for hundreds of structural projects, including the Rion-Antirion cable-stayed bridge (1999-2004, 2883 m, in Greece); the Anatolian Viaduct (2000-2003, 119 spans, in Turkey); the new housing system after L’Aquila earthquake (2009-2010, with 185 buildings seismically isolated with more than 7,000 devices, completed in about six months); the construction of 103 schools in Costa Rica (2013-2018, for the IAD bank); the assessment and strengthening program in the area of Groningen, in The Netherlands (2013-2024, due to problems of induced seismicity). He has been consistently active in conceptual innovation in seismic design, focusing on masonry in his early days, bridges, displacement-based design and seismic isolation from the nineties.
