APPLICATION OF DAMAGE DETECTION ALGORITHMS TO BRIDGE FIELD TEST DATA

Field data from experiments where damage has been introduced systematically to a structure are difficult to find yet essential for validation of damage detection algorithms used in structural health monitoring. Such an experiment was recently conducted by Vibration Consulting Engineers in Vienna, Austria and the data were made available to the authors. In this paper, the results from the analysis of the data are summarized and the efficacy of the damage detection algorithms is assessed. It is found that in most cases the algorithms are able to identify the damage. Good results are obtained when damage is quantified and localization can be explained
