| Abstract | This IREE Supplement provided funds for travel and subsistence for the authors to spend 3-4 months in Liège, Belgium, working with the Vibration and Structural Identification group in the Aerospace and Mechanical Engineering department of the University of Liège (ULg). This research group has developed expertise in system identification and nonlinear dynamics. Prof. Johnson was at ULg for 3 months in the January-May 2007 timespan, and Mr. Fu was there for 3 months in April-July 2007 (the partial but not complete overlap was intentional so that Mr. Fu would have a smoother transition but not complete overlap so that he would experience working directly with the Belgian researchers). The particular focus of the collaborative research was two-fold: exploring the performance-robustness trade offs in various linear and nonlinear structural control strategies, and applying the concept of a nonlinear energy absorber to civil engineering structures subjected to earthquake hazards. This research, which is of larger scope than could be accomplished in a few short months, is ongoing and will form the basis for long-term collaboration with the Belgian colleagues: Prof. Gatan Kerschen, Mr. Régis Viguié and Prof. Jean-Claude Golinval. In addition to the research benefits, the authors had significant opportunities to learn about the people, culture and history of Belgium - partially through weekend sightseeing trips, but particularly through communicating with people (partially in French, partially in English) at the University and in the community. |

| Bio | Erik A. Johnson completed his B.S. in Aeronautical and Astronautical Engineering at the University of Illinois at Urbana-Champaign in 1988, graduating with highest University honors, and a minor in French Studies. In graduate school at Illinois, he focused on structural control, structural system identification, and computational stochastic dynamics, receiving the Jefferson Goblet award from the American Institute of Aeronautics and Astronautics for best student-authored paper at the 1994 AIAA SDM conference. Dr. Johnson completed his M.S. and Ph.D. degrees in Aero/Astro Engineering, in 1993 and 1997, respectively. From 1997-1999, he was a visiting assistant professor at the University of Notre Dame. In 1999, Dr. Johnson joined the faculty of the University of Southern California as an assistant professor of Civil Engineering, where he teaches mechanics, structural dynamics and uncertainty quantification; he was promoted to associate professor with tenure in 2005, and appointed as associate chair of the department in 2007. He is the recipient of an NSF Early Faculty Career Development (CAREER) Award, has authored or co-authored numerous journal and conference papers, is the co-editor of Stochastic Structural Dynamics, published in 1999, and currently serves as the Chair of the ASCE EMD Technical Committee on Structural Health Monitoring and Control and as an Associate Editor of the ASCE Journal of Engineering Mechanics. Tat S. Fu completed his B.S. in Civil Engineering at the University of Southern California (USC) in 2003, with a minor in mathematics. He then stayed at USC for his graduate studies and completed his M.S. in Civil Engineering and M.S. in Electrical Engineering in 2004 and 2006, respectively. His research interests include a tool for computing the response of simple stochastic dynamical systems, wireless structural health monitoring strategies and distributed damping of structures using architectural elements. Mr. Fu will complete his Master of Building Science in the School of Architecture in December 2007 and his Ph.D. in Civil Engineering in May 2008. |
