From damage identification to reliability assessment.
Original language description
The analysis of damage and variability of material properties (stiffness) along the structure is essential to capture the stage of the structure and to predict a future behavior including reliability assessment. Two identification methods are used: artificial neural network (ANN) combined with stochastic analysis and sensitivity based method. The proposed methodology utilizes the dynamic response of structures when results of modal analysis are the input parameters (frequencies, modeshapes, etc.). Moreover, a logically complex and systematic treatment of concrete bridges is suggested in the paper. A statistical simulation of the Monte Carlo type is utilized twice in our approach: (i) at the stage of preparation of the training set for ANN and/or in sensitivity based identification and, once the model parameters are identified, (ii) to obtain the statistics of the response and for reliability calculations. The procedure can be outlined as follows: Experiment/health monitoring of bridge;
