Operational Modal Analysis

About the Authors

Mohammad Noori is an Emeritus Professor of Mechanical Engineering at Cal Poly, San Luis Obispo, and a Visiting Professor at the School of Civil Engineering, University of Leeds, UK where he also serves as a founding director of Intelligent and Resilient Infrastructure Center, (https://www.iri-center.org/). Noori is a Fellow and Life Member of the American Society of Mechanical Engineers. His work in modelling the complex hysteretic behavior of structural systems, including pinching phenomenon, cited in the literature as the Bouc-Wen-Baber-Noori (BWBN) model, has been widely utilized in nonlinear random vibrations; for seismic response analysis of concrete structures and has been incorporated in Open Sees seismic analysis program. His work in non-zero mean, non-Gaussian response analysis of hysteretic systems are also original contributions. Noori has also carried out pioneering work in seismic isolation of secondary systems and holds 2 US patents in that area and has been a pioneer in the application of artificial intelligence methods for structural health monitoring. He has authored over 300 refereed papers, 7 scientific books, 32 book chapters and has edited 25 technical and special journals, and archival volumes. Noori has supervised over 100 graduate students and post-doc scholars and has presented over 100 keynotes, plenaries, and invited talks. He is the founding Executive Editor of an international journal, has served on the editorial boards of as the associate editor of over 12 other journals and as a member of numerous scientific and advisory boards. Noori directed the Sensors Program at the National Science Foundation in 2014. He served as the dean of engineering at Cal Poly, as the Higgins professor and head of mechanical engineering at WPI and as the Reynolds Professor and head of mechanical and aerosphere engineering at NC State University. Noori also served as the Chair of the national committee of mechanical engineering department heads and was one of 7 co-founders of the National Institute of Aerospace, in partnership with NASA Langley Research Center.

Carlo Rainieri is currently senior researcher at the National Research Council of Italy. His research interests are in the fields of civil Structural Health Monitoring, Operational Modal Analysis, and smart materials. He has joined several research projects focused on civil Structural Health Monitoring. He is Member of the Scientific committee of the IOMAC Association since 2015. In 2019 he received the IOMAC scientific Award for his contribution to the development of Operational Modal Analysis. He was Chair of the 8th Civil Structural Health Monitoring Workshop (2021) and of the 10th International Operational Modal Analysis Conference (2024). In 2021 he was also appointed as Council Member of the International Society for Structural Health Monitoring of Intelligent Infrastructure. He is author of the first book on Operational Modal Analysis appeared in the literature ("Operational Modal Analysis of Civil Engineering Structure: An Introduction and Guide for Applications") and of about 200 scientific papers published on international peer-reviewed Journals and National and International conference proceedings. His main achievements in the field of Operational Modal Analysis and civil Structural Health Monitoring concern the development of data processing methods for vibration-based Structural Health Monitoring applications, including original automated Operational Modal Analysis procedures and novel methods for compensation of environmental/operational influence on modal properties. He is also founder and former CEO of S2X s.r.l. (www.s2x.it), a spin-off company of the University of Molise aimed at providing highly qualified solutions and services in the fields of Civil Structural Health Monitoring and Operational Modal Analysis.

Carmelo Gentile is a full professor of Structural Engineering at the Department of Architecture, Built environment and Construction engineering (DABC), Technical University of Milan (Politecnico di Milano), Italy. He has been the author or co-author of more than 300 technical and scientific papers. His main research expertise and interests are Bridge engineering, Cultural Heritage structures, Dynamic tests and continuous monitoring of bridges and historic structures, Earthquake engineering, Modal and structural identification, Structural Dynamics, Vibration-based damage assessment, Microwave Remote Sensing. Dr. Gentile serves as a member of the Scientific Committee of the main international conferences on Structural and Experimental Dynamics (e.g., EURODYN, EVACES, IOMAC, SMART, etc). He is also a member of the Scientific Committee of the Laboratory of Testing Materials and Structures (LPM), Politecnico di Milano, since 2019. He has been the Scientific consultant of the Laboratory of Vibrations and Dynamic Monitoring of Structures (section of LPM) since 2006. He is also responsible for the the Laboratory of Vibrations and Dynamic Monitoring of Structures, for the full-scale testing and/or continuous dynamic monitoring of more than 200 bridges, including several arch bridges and cable-stayed bridges and the viaducts of the new A58 motorway. He is also the coordinator and responsible for several projects of vibration-based SHM, such as the dynamic monitoring of the historic San Michele bridge (2011-2015), the structural monitoring of the Milan Cathedral since 2018, the continuous dynamic monitoring of the Brivio arch bridge (1917) since 2020 and the dynamic monitoring of a steel-concrete composite bridge overpassing the A4 motorway (since late January 2021). Dr. Gentile also serves as a member of the Scientific Committee and of the Board of the FABRE Consortium, involved in research in the field of structural assessment and monitoring of existing bridges. He has delivered invited keynote lectures at various international conferences (e.g., SF&R 2022, JISDM2019, IOMAC 2019, ICEM 2018, SF&R 2018, EVACES 2013, IABSE Conference Rotterdam 2013, EURODYN 2011).
