Structural health monitoring is a topic of interest due to its impact on infrastructure maintenance programs. It is necessary to consider whether or not there is damage, where it is located, its magnitude and the estimated residual useful life. The methodology implemented is to propose “damage scenarios” in a numerical model of the system, including uncertainties in the physical characteristics through random fields. For each damage scenario, the statistics of the dynamic properties, modes and frequencies are performed on the random variables by applying Monte Carlo. Once an acceleration-time measurement is recorded and the dynamic parameters are identified, the “a priori” probability of obtaining these dynamic parameters for each damage scenario is calculated with the statistics. Applying Bayesian inference, the “a posteriori” probability is calculated given the recorded measurement. The process is repeated until convergence. The final result indicates the probability of occurrence of each damage scenario. It is applied to a slab bridge model and it is concluded that the best option is to use the frequency vector as dynamic parameters.
