- Abstract
- Application of system identification techniques in earthquake engineering research is described with emphasis on the damage evaluation of existing structures. Two recent developments have increased motivation to use structural identification for locating transducers for strong motion recording: the changing approach to instrumenting structures to determine their earthquake response; and the increasing development of more accurate earthquake forecasts which can result in prediction of at least some earthquakes. The report considers use of identification in the following situations involving existing structures: (1) analysis of dynamic test data; (2) analysis of strong-motion earthquake response data; and (3) analysis of post-earthquake data. Problems common to each of these applications are reviewed. An approach to resolve the uncertainty problem in analysis is suggested.
