Three Experimental Applications of Health Algorithms to Improve Infrastructure Inspection

Abstract : This paper presents three applications of structural health evaluation from data collection to damage location. The first test setup was a standard railway track with an adjustable sleeper to allow for artificial defects. The second test setup was a student-built reinforced concrete bridge with various rubber bearings to represent joint softening. The third test location was a skewed on-campus highway bridge built in 1940 with no maintenance record. The obtained data sets were analyzed with an in-house structural health evaluation program, performing modal decomposition and applying twelve different damage detection algorithms.
