METRANS RESEARCH PROJECT Project 01-10 PARAMETRIC FREQUENCY DOMAIN IDENTIFICATION USING VARIABLE STIFFNESS AND DAMPING DEVICES
Introduction A two-bay by two-bay four story steel frame owned by the University of British Columbia has been selected as a benchmark structural model to test damage identification techniques. The structure is approximately in a 1:4 scale and has member sizes and details that may be found in Ventura et al. (1997). Testing to generate data for damage identification is scheduled to begin in the summer of 2000. Before addressing the full complexity associated with real experimental data, however, it was considered appropriate to examine a number of cases using simulated data. For this purpose, mathematical models of the test structure with various degrees of refinement have been formulated and used to generate data for various damage scenarios. This paper documents the damage identification approach used by the authors and presents the results obtained for the cases considered thus far.
