Paper Abstract
This paper presents the development of a Bayesian framework for optimizing the design of a structural health monitoring
(SHM) system. Statistical damage detection techniques are applied to a geometrically-complex, three-story structure
with bolted joints. A sparse network of PZT sensor-actuators is bonded to the structure, using ultrasonic guided waves in
both pulse-echo and pitch-catch modes to inspect the structure. Receiver operating characteristics are used to quantify
the performance of multiple features (or detectors). The detection rate of the system is compared across different types
and levels of damage. A Bayesian cost model is implemented to determine the best performing network.
