N2 - In this paper, a general method for probabilistic model and reliability updating using response measures is presented. The prior probability density functions for model parameters are derived according to the principle of Maximum Entropy (MaxEnt) when partial information is available. A posterior is formulated using the principle of Minimization of Discrimination Information (MDI) to perform probabilistic model and reliability updating when new inspection data are available. Simulation-based approaches are adopted to calculate the asymptotic solutions for the prior and posterior densities. A realistic fatigue crack growth example with experimental data is presented for illustration and validation of the proposed method.
