| Abstract: | Dynamic testing of constructed systems was initiated in the 1960’s by civil engineers
interested in earthquake hazards mitigation research. During the 1970’s, mechanical engineers
interested in experimental structural dynamics developed the art of modal analysis. More
recently in the 1990’s, engineers from different disciplines have embarked on an exploration of health monitoring as a research area. The senior writer started research on dynamic testing of
buildings and bridges during the 1970’s, and in the 1980’s collaborated with colleagues in mechanical
engineering who were leading modal analysis research to transform and adapt modal
analysis tools for structural identification of constructed systems. In the 1990’s the writer and his associates participated in the applications of the health monitoring concept to constructed systems. In this paper, the writers are interested in sharing their experiences in dynamic testing
of large constructed systems, namely, MIMO impact testing as well as output-only modal analysis, in conjunction with associated laboratory studies. The writers will try to contribute to answering some questions that have been discussed in the modal analysis and health monitoring community for more than a decade: (a) What is the reliability of results from dynamic testing of
constructed systems, (b) Can these tests serve for health monitoring of constructed systems? (c) Are there any additional benefits that may be expected from dynamic testing of constructed systems?
(d) Best practices, constraints and future developments needed for a reliable implementation of MIMO testing and output-only modal analysis of constructed systems for health monitoring and other reasons. |
