Enrico Spacone is Professor of Structural Engineering at the University of Chieti. He is also member of the Faculty of Engineering at the University of Colorado, Boulder. His main research interests are: nonlinear modelling of building and bridges, bond-slip problems in reinforced concrete and steel-concrete mixed structures, strengthening/retrofitting of existing structures with Fiber Reinforced Polymers (FRP), computational methods in nonlinear frame analysis, application of nonlinear analysis in seismic design codes. He has published over 60 papers in international journals and conferences. He is an Associate Editor for the ASCE Journal of Structural Engineering. He has carried out research work in collaboration with several international and national research groups. He is involved in the National Science Foundation George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES).

Izuru Takewaki is a President of Kyoto Arts and Crafts University and Professor emeritus of Kyoto University. He was the 56th President of Architectural Institute of Japan (AIJ) during 2019-2021.  He is the Field Chief Editor of Frontiers in Built Environment.  His main interests are passive structural control, robust and resilient structural design of buildings, structural optimization, inverse problem in vibration, soil-structure interaction, critical excitation method for worst-case analysis, etc. He has published over 330 International Journal Papers and six monographs in English. The recent one is ‘An Impulse and Earthquake Energy Balance Approach in Nonlinear Structural Dynamics, CRC Press, 2021’ based on an innovative energy approach.  He was awarded numerous prizes, e.g. Research Prize of AIJ (2004), 2008 Paper of the Year in J. of The Structural Design of Tall and Special Buildings, Prize of AIJ for Book (2014), Papers of the Year 2022 (Japan Architectural Review (JAR), Wiley), Most Cited Paper Award 2024 (JAR).

He graduated from Istanbul Technical University (ITU), Department of Civil Engineering in 1987. He completed his Ph.D. in 1998 at the ITU Institute of Science and Technology. He was a visiting researcher at the University of Tokyo and Building Research Institute (BRI) in Japan in 1993 and New York State University at Buffalo in the United States in 2004. His main study subjects are energy-based analysis of structural systems, energy dissipative systems in earthquake engineering, and precast concrete structures. He has conducted many experimental studies in the laboratory on structural members and systems subjected to static, dynamic, and fatigue loads. He was a researcher in TÜBİTAK, JICA, NATO, and European Community projects. He continues to serve as Türkiye's representative of UNESCO IPRED (International Platform for Earthquake Damage Reduction). He has many papers in structural and earthquake engineering. He co-authors textbooks on structural analyses and handbooks on precast concrete structures. Currently, he is the director of the Structural and Earthquake Engineering Laboratory of ITU.
