Abstract

A Bayesian framework for model assessment, including an analysis of uncertainties due to small sample size, model inexactness and measurement error, was described in a paper by the first author in the previous IFIP Conference [1]. In this paper, we present computational methods for numerical evaluation of the statistical properties of the model parameters. These include efficient integration and simulation methods aimed at computing the marginal distributions and marginal and joint moments of the uncertain parameters. In the second part of the paper, the proposed methods are employed in evaluating several models recommended by the American Concrete Institute for design of concrete structures. To the authors’ knowledge, these applications are first attempts at rigorous evaluation of some widely used models in structural engineering.
